A well regulated Militia, being necessary to the security of a free State, the right of the people to bear Arms, shall not be infringed.
The Second AmendmentINTRODUCTION
For most of its existence, the Second Amendment was “virtually ignored” by Constitutional scholars and the US Supreme Court.Footnote 1 Recently, however, a veritable cottage industry has developed over the meaning and origin of the right to bear arms. Two distinct camps have surfaced, largely following the lines drawn in the contemporary gun control debate. First are the so-called “Standard Modelers,” who argue that individuals have a right to bear arms for self-defense, the defense of the state, and, in the most extreme examples, to overthrow the government should it become tyrannical.Footnote 2 Second are those who view the Second Amendment as a collective right vested in the state militias for the purposes of law enforcement,Footnote 3 to protect against foreign aggression, to quell domestic insurrection,Footnote 4 and as a check against the overreach of the power of the federal government.Footnote 5 This debate sheds more heat than light and has, therefore, appropriately been termed “the Great American Gun War.”Footnote 6 Advocates of gun rights typically emphasize the individualist view of the Second Amendment while proponents of gun control tend to emphasize the collective-rights interpretation.Footnote 7
Despite the enormous gulf between them, however, both sides agree that the right to bear arms was adopted in order to supplement domestic policing powers, provide a defense against foreign aggression, and offer a powerful counterbalance against the new federal government. This paper focusses on the latter point, which has been at risk of being lost in the ongoing debate. Freedom from arbitrary authority was a major motivation underlying the American Revolutionary War and it remained a prevalent concern as the former British colonies came together to create a new union. Under the proposed Constitution, the former colonies would lose much of the independent military power they previously enjoyed to a new federal government, which would have the power to create and maintain a professional army, call forth the state militias, and pay for them by raising taxes. The fear that this new government might, if not properly checked, assume the worst aspects of British colonial rule, which had just been shed, set the stage for the adoption of the Second Amendment. Advocates of the Second Amendment argued that the right to bear arms would help ensure that the states would remain free from tyranny, whether the source was foreign or domestic.
This paper uses a game-theoretic analysis to shed light on the Second Amendment. Game theory is the study of strategic interactions. It is particularly useful for understanding the incentives for conflict and cooperation between rational actors, and modeling the strategies they employ to manipulate them. Game theory has been used extensively in the study of international relations to model the interaction between states under the prevailing conditions of international anarchy.Footnote 8 While most extant research on the postcolonial period approaches the United States as a “cohesive and fixed ‘nation’,” a growing body of literature has come to consider the former colonies as lacking an overarching authority capable of binding commitments, arbitrating disputes, or providing for their collective security.Footnote 9 Totten writes that they “often acted like those on the European continent: they clashed over commerce and territory, formed economic ‘pacts’ with one another against other parts of the union, gathered their own armies, chartered their own navies, and pursued separate foreign policies.”Footnote 10 Indeed, much like states in the international system, the former colonies were largely independent actors operating in conditions of anarchy. The proposed Constitution, however, planned to change this by binding them together in a union with a strong central authority. Seen in this way, the founding of the United States can be viewed as a type of contracting problem to which game theory is well suited.
In game-theoretic terms, the former colonies suffered a “commitment problem.” They wanted to create a government in order to arbitrate disputes amongst them and provide for their collective security (amongst other things), but feared that it might turn against them, tyrannizing them much as the British had done.Footnote 11 In other words, they wished to cooperate, but worried about the possibility of defection. If they could not overcome this problem, ratification of the proposed Constitution would prove a challenge, perhaps even leading the newfound union to unravel.Footnote 12 In enshrining a Constitutional right to bear arms, the former colonies adopted a balancing strategy (amongst other things) to overcome their fear of defection.Footnote 13 It did so in two distinct ways. First, it enabled the states to retain their militias for the purposes of defense (indeed it precluded the federal government from disbanding them), thereby militating against the need for a large standing federal army, which could be used for the purposes of domestic repression. Second, it created a balance of power between the former colonies and federal government, deterring overreach by the federal government.Footnote 14 Some authors argue that the right to bear arms vested the states with the offensive means with which to directly confront a tyrannical government by force. The resulting government was then a novel form of federalism, sharing authority between multiple levels. In this way, it departed from the Weberian ideal type of statehood, characterized by the “monopoly over the legitimate use of physical force within a given territory.”Footnote 15 Indeed, the Second Amendment created an oligopoly over the use of force, diffusing coercive power through the population, the states, and the federal government in a deliberate attempt to weaken the power of the federal government.Footnote 16
This article proceeds as follows: I begin by discussing the credible-commitment problem from a game-theoretic perspective and the various solutions in the prevailing literature that have been proposed to resolve it. I then proceed to examine the decision to adopt the Second Amendment. I rely extensively on historical justifications, which were widely circulated in the Federalist Papers penned by Alexander Hamilton (“Publius”), the countervailing anti-Federalist essays of Robert Yates (“Brutus”), and others. I also make reference to the early modern writings of Machiavelli and the works of various seventeenth- to nineteenth-century anti-absolutist English writers (so-called Whigs), whom numerous Constitutional scholars cite as a driving intellectual influence for the Second Amendment.Footnote 17 I offer a novel game-theoretic reading of the Second Amendment. Drawing insights from the study of international security, I argue that the right to bear arms can be understood as a rational strategy adopted by actors operating under conditions approximating anarchy to help overcome their commitment problems. Finally, I discuss the evolution of the coercive apparatus in the United States, which has come to more closely resemble other states over time. In response to external forces, the federal government gradually developed a more robust and centralized coercive capacity, and, while the states continue to maintain powerful checks against federal overreach, they let their militias decline as the fear of tyranny receded.
This paper proposes to shed new light on one of the more idiosyncratic chapters of the Constitution. While recent research has tended to emphasize the socioeconomic and ideological aspects of the founding of the United States, it would not likely have succeeded without addressing the underlying security concerns. Totten writes, “Without the survival of the parts of the union the founders most likely could not have realized other motivations that they may have had for forming a new government. By necessity, security was one of if not the primary reason for constitutional reform.”Footnote 18 In creating a government capable of addressing the prevailing security concerns, however, the founders created a new problem. A government powerful enough to arbitrate disputes between the former colonies and provide security against external threats would also be strong enough to tyrannize them. In other words, they had turned an external security problem into a domestic commitment problem. Insights from game theory allow us to understand the Second Amendment as a partial solution. The right to bear arms reduced the likelihood of federal overreach by eliminating the need for a large standing army and deterred any incentive the federal government might have to defect by providing a counterbalance to federal forces, which could be used in the event that defection did occur. In sum, the Second Amendment mitigated the fear of defection and provided an insurance policy if those mitigation efforts failed. In so doing, the Second Amendment helped alleviate the states’ commitment problems in part, thereby facilitating the timely passage of the Constitution. However, the utility of using a game-theoretic approach promises to extend beyond the particularities of eighteenth-century America. Insights from this case can enhance our understanding of contemporary examples of supra-national contracting, such as the European Union.Footnote 19 States jealously guard their sovereignty. Voluntary unions are, therefore, quite rare. Indeed, few states have willingly contracted away their sovereignty as the former American colonies did.Footnote 20 The American case affords insights not only into the potential reasons for contracting, but also into the limits of contracting, which is of particularly vital importance now that so much international contracting appears to have stalled.Footnote 21 Though often considered less salient than other aspects of the Constitution, the Second Amendment is therefore worthy of thorough scrutiny.Footnote 22
WEAPONS AND THE PROBLEM OF CREDIBLE COMMITMENTS
The main hypothesis of credible-commitment theory is that actors will tend to have difficulty contracting (i.e. making agreements) unless they are able to convince each other that they will to adhere to an agreement in the future.Footnote 23 In the absence of an authority that can bind commitments, cooperation tends to break down, even if actors wish to cooperate. In other words, actors experience a prisoner's-dilemma-like scenario: despite their desire to cooperate, the fear of future defection will prevent them from reaching mutually beneficial agreements.Footnote 24 This may be because they are cynical (i.e. they don't believe the other side) or because of “time-inconsistent preferences” (i.e. they fear that their interlocutor's interests may change in the future).Footnote 25 This problem is said to be particularly acute where defection might imperil survival, for example during armed conflict. Indeed, the credible-commitment problem often leads violence to persist even when actors wish to terminate it.Footnote 26
However, the credible-commitment problem is not indelible. Indeed, cooperation is possible even when trust is low and the future uncertain. Scholars describe several strategies that actors employ to alter the prevailing incentive structures in order to mitigate the credible-commitment problem, several of which I will outline. First, they can introduce domestic audience costs. In other words, actors can make public statements such that they would be open to criticism from their constituents or lose public support if they reversed themselves, thereby raising the price of reneging on an agreement.Footnote 27 Political and business leaders, for example, often make public promises that would be damaging to their reputation to go back on. Second, actors can send costly signals of their desire to cooperate.Footnote 28 Kydd defines costly signals as “unilateral cooperative gestures that … involve some vulnerability on the part of the side that makes them.”Footnote 29 Costly signals generally consist of some form of self-binding. For example, states may unilaterally reduce weapons stocks or lower their military readiness in order to signal their benign intent or deescalate tensions. Costly signals work by “persuading the other side that one is trustworthy by virtue of the fact that they are so costly that one would hesitate to send them if one were untrustworthy.”Footnote 30 Third, actors can delegate enforcement to an external party. Third parties can provide robust guarantees if they have the necessary interest and sufficient resources to punish defection.Footnote 31 For example, states routinely enlist international organizations to enforce the rules of various treaties. Finally, actors can balance against the source of the commitment problem. Where there is no overarching authority capable of enforcing agreements, actors are said to turn to self-help mechanisms to ensure their survival. They do so, according to realists, by balancing. Balancing is the attempt to equalize power, making it more difficult and, therefore, less likely that others will take advantage of an actor or otherwise defect from an agreement.Footnote 32 Balancing encompasses a range of activities, including diplomacy, alliance formation, and, most crucially, military preparation.Footnote 33 An armed population is one such example, and is the focus of this paper.
Arms can be used to protect actors against grave threats to their physical security by providing the material tools for their defense. They can be used to repel attacks, hold territory, and extract resources necessary for survival. Arms can be used to counter an attack or preempt a potential threat. Even small numbers of weapons may suffice for these purposes, particularly when they are organized, for example in the form of a militia. Contrary to the claims of offensive realists, who argue that actors require a preponderance of power in order to ensure their survival, actors may tolerate power asymmetries without compromising their security.Footnote 34 Indeed, the weak often prevail against more powerful actors. Small numbers of weapons used by highly motivated groups with sufficient knowledge of their surroundings regularly manage to repel and, in some cases, overcome much stronger adversaries, particularly when employing the so-called tactics of asymmetric or guerilla warfare.Footnote 35
In so doing, weapons help change the calculus of the credible-commitment problem. They mitigate the risk of defection by providing the means of defense and the ability to punish defections, thereby enabling groups to assume and manage risks and uncertainty about the future. An armed population, then, is not so much an alternative to domestic audience costs, costly signals, and third-party enforcement, as it is an insurance policy against their failure. And, unlike external enforcement, which delegates the commitment problem to a third party, weapons provide the means for self-help. In other words, should actors retain the ability to deter defection and defend themselves, they need not turn to a third party to enforce an agreement. While none of these strategies fully remediate the credible-commitment problem, they do help shift the prevailing incentive structure from one in which there may be an incentive to break a deal to one in which there is less incentive to do so, thereby increasing the likelihood of compliance and cooperation. They help shift the calculation involved in defecting from the positive to the negative side of the ledger, thereby allowing actors to make more credible commitments to each other. If actors can convince each other that they won't defect, or convince themselves that they will survive defection, they will be more likely to enter into commitments with each other.
THE SECOND AMENDMENT
During the American War of Independence, several colonies, now calling themselves “states,” organized a loose confederation for the purposes of “common defense” (amongst others). However, even before the conclusion of the war it had become increasingly evident that it was inadequate to that task.Footnote 36 The confederation struggled to fight effectively against the British;Footnote 37 it suffered persistent budgetary shortfalls, having been granted no central taxation mechanism;Footnote 38 and it was unable to arbitrate the increasing number of conflicts that arose between the states.Footnote 39 Even after winning independence from Britain, security threats loomed, particularly on the peripheries near the Spanish territories and the western frontier.Footnote 40 And, indeed, the states themselves posed potential security threats to each other.Footnote 41
In 1787 a constitutional convention was convened in an effort to strengthen the confederation and shore up the fledgling central government. After several false starts, a new Constitution was drafted with a particular eye towards the provision of security.Footnote 42 The Constitution created a more robust central government with the power to raise armies, and to organize, arm, discipline, and call forth the state militias (Article I, Section 8); declare wars and suppress domestic insurrections (Article I, Section 7); and, perhaps most importantly, pay for these through an effective taxation mechanism.Footnote 43 No longer would each state separately enjoy “sovereignty, freedom, and independence” as they had previously. Indeed, under the proposed Constitution the states would lose most of their independent military capacity, receiving little more than the power to appoint officers and train the militias according to the rules set out by Congress.Footnote 44
The new Constitution was not without criticism. Though it contained a then-novel tripartite system of checks and balances against the imposition of arbitrary authority (i.e. a separate executive, legislature, and judiciary), so-called Anti-Federalists grew concerned that a stronger federal government would come at the expense of, or even jeopardize, individual and state's rights.Footnote 45 They were concerned that a large standing army could be used as a vehicle for tyranny.Footnote 46 With its newfound ability to collect taxes and raise a large army and federalize the militias, some worried that the new federal government would be able to pursue unpopular or even unlawful polici.Footnote 47 Others were anxious that the federal government, with its expanded powers to equip the militias, would instead disarm or dismantle them, or otherwise let them fall into a state of disrepair, leaving the states altogether defenseless against arbitrary incursions into their authority (possibly even leading to their destruction at the hands of the federal government).Footnote 48 For example, Founding Father and Anti-Federalist George Mason argued that the new Constitution would give the federal government the power to destroy the state militias, “rendering them useless – by disarming them.”Footnote 49 Luther Martin, also a Founding Father and Anti-Federalist, argued in front of the Maryland legislature that “if the general government should attempt to oppress and enslave them, [the states] could not have any possible means of self-defense.”Footnote 50 The best-known Anti-Federalist tract, written by “Brutus” stated,
The liberties of a people are in danger from a large standing army, not only because the rulers may employ them for the purposes of supporting themselves in any usurpations of power, which they may see proper to exercise, but there is a great hazard, that an army will subvert the forms of the government, under whose authority, they are raised, and establish one, according to the pleasure of the leader.Footnote 51
Such feelings were no doubt colored by recent events (i.e. the use of a standing army by the British in an attempt to enforce unpopular legislation on the colonies and suppress the revolution that followed) as well as by the historic use of standing armies to suppress liberties in England (more on this below).Footnote 52
Some Federalists similarly feared government meddling. For example, Pennsylvania delegate to the Continental Congress Tench Coxe feared that “civil rulers, not having their duty to the people duly before them, may attempt to tyrannize, and as the military forces which must be occasionally raised to defend our country, might pervert their power to the injury of their fellow citizens.”Footnote 53 However, they generally had more faith that the checks and balances embedded in the Constitution would restrain the ambitions of the federal government.Footnote 54 Indeed, Hamilton dismissed Anti-Federalist concerns as “far fetched … and extravagant” and Madison called their fears “misguided exaggerations.”Footnote 55
Nevertheless, the work of the Anti-Federalists proved extremely effective: several states threatened to ratify the proposed Constitution only if changes were made. Madison proposed offsetting a standing army with the militias, while Anti-Federalists proposed limiting the size of a standing army or eliminating it altogether, instead relying on the militias for the purposes of defense.Footnote 56 In the end, a compromise was reached, enabling the timely passage of the Constitution. Rather than changing the text, which was itself a product of difficult compromise, the states agreed to draft a subsidiary document, “mollifying” the Anti-Federalists.Footnote 57 Twelve amendments were presented to Congress, ten of which were passed to become the core of the Bill of Rights. Where the Constitution increased the power of the federal government, these amendments acted to constrain it by enumerating separate individual and state rights, the right to bear arms being the second of these.Footnote 58 Kates argues that the Second Amendment was the most crucial component of the compromise necessary to ratify the Constitution. He writes,
only four states suggested that the rights to assemble, to due process, and against cruel and unusual punishment be guaranteed; only three states suggested that freedom of speech be guaranteed or that the accused be entitled to know the crime of which he would be tried, to confront his accuser, to present and cross-examine witnesses, to be represented by counsel, and to not be forced to incriminate himself; only two states proposed that double jeopardy be barred …
yet five states called for an amendment guaranteeing the right to bear arms.Footnote 59 In either case, the Bill of Rights, which included the right to bear arms, helped satisfy the holdout states, thereby shoring up the Constitutional process and stabilizing the fledgling union.
American Constitutional scholars cite two main intellectual sources for the Second Amendment: English WhigsFootnote 60 and Machiavelli, whom the Whigs made frequent references to.Footnote 61 According to Machiavelli, ancient Rome thrived when there wasn't a class of professional soldiers, but succumbed to tyrannical rule when a standing army persisted for an extended period.Footnote 62 For Machiavelli, military strength was essential for defensive purposes—ensuring the independence of one republic from another. However, when coercive power was centralized, Machiavelli argued, professional soldiers used their weapons to subordinate the general population, which was powerless to resist.Footnote 63 For Machiavelli, then, military strength is necessary to maintain the freedom of the state, but military strength concentrated in the hands of the few was anathema to freedom. An armed population, however, could defend against foreign aggression while preventing the emergence of a corrupt ruling class, which would likely result from the centralization of power in the hands of the few.Footnote 64 Though separated by hundreds of years, the Whigs draw similar conclusions to Machiavelli regarding standing armies and the virtue of an armed population.Footnote 65 Indeed, Whig writers made frequent reference to ancient Rome in arguing for an armed citizenry as a counterbalance to the federal government. It is for this reason that Pocock has called the founding of the new republic a “Machiavellian moment.”Footnote 66
DISCUSSION
In drafting the Constitution, the Federalists wished to strengthen the new republic in an effort to more effectively arbitrate the increasing number of disputes between them and better provide collective security.Footnote 67 At the same time, Anti-Federalists feared the consequences of doing so. In empowering the federal government, the states had created the means for their own dispossession. The Constitution created a standing army; placed the responsibility to equip the state militias in the hands of the federal government, which might neglect it; and created a federal right to take control of the militias. As a result, the states had created a credible-commitment problem. They could not trust the federal government not to use its newfound power to tyrannize them, as the British had done previously. There are, however, various strategies available to remediate commitment problems, many of which were adopted. The states sent costly signals of their desire to cooperate, introducing domestic audience costs through regularized elections, and they attempted to introduce third-party enforcement through the creation of the strong federal government to arbitrate disputes between them.Footnote 68 They were also particularly alive to the virtue of an armed population, an idea lent them from Machiavelli and the Whigs.
The argument that an armed population helps prevent a tyrannical government from arising comes in what might be considered a strong and weak variant, roughly corresponding to the debate between Standard Modelers and the advocates of collective rights. The weak variant, typically associated with collective-rights advocates, holds that the right to bear arms acts to limit the need for a strong centralized army.Footnote 69 “If standing armies are dangerous to liberty,” Alexander Hamilton writes,
an efficacious power over the militia, in the body to whose care the protection of the State is committed, ought, as far as possible, to take away the inducement and the pretext to such unfriendly institutions. If the federal government can command the aid of the militia in those emergencies which call for the military arm [it would] render a [federal] army unnecessary.Footnote 70
The federal government would have little need to raise a large standing army so long as the states retained their militias for the purposes of collective defense. As a result, the federal government would be limited in its ability to interfere in the affairs of the states. Moreover, the federal government was thought to be less likely to exceed its power because it would be reliant on the states for defense. “At the time of the framing,” Reynolds writes, “the primary means of executing the law or quelling insurrection was by calling out the militia, a simple refusal on the part of the militia to perform its duties would be enough to frustrate tyranny pretty thoroughly.”Footnote 71
The strong variant of the right to bear arms is often called the “insurrectionist” interpretation because it contends that the Second Amendment contains the right to rebel against arbitrary authority, much as the colonists rebelled against the British.Footnote 72 This view is most closely associated with the Standard Model. On this reading, the Second Amendment provides the citizenry with both the means (“arms”) and the justification (“the security of a free State”) to resist and even overthrow their government should it become tyrannical.Footnote 73 In other words, the right to bear arms is guaranteed by the government in order that they can be turned against the government. Standard Modelers cite numerous sources for this interpretation, including Thomas Jefferson,Footnote 74 Alexander Hamilton,Footnote 75 and James Madison. It is worth quoting Madison, who authored the Second Amendment, at length:
Let a regular army, fully equal to the resources of the country, be formed; and let it be entirely at the devotion of the federal government: still it would not be going too far to say that the State governments with the people on their side would be able to repel the danger. The highest number to which, according to the best computation, a standing army can be carried in any country does not exceed one hundredth part of the whole number of souls; or one twenty-fifth part of the number able to bear arms. This proportion would not yield, in the United States, any army of more than twenty-five or thirty thousand men. To these would be opposed a militia amounting to near half a million of citizens with arms in their hands, officered by men chosen from among themselves, fighting for their common liberties and united and conducted by governments possessing their affections and confidence. It may well be doubted whether a militia thus circumstanced could ever be conquered by such a proportion of regular troops. Those who are best acquainted with the late successful resistance of this country against the British arms will be most inclined to deny the possibility of it.Footnote 76
Unlike the other aspects of the Constitution and the Bill of Rights, which prohibit or proscribe government behavior, on this view the Second Amendment threatens implicit consequences should the government exceed its authority.
Perhaps not surprisingly, the view that the Constitution contains the seeds of its own destruction has inspired legions of detractors, particularly in light of Article I, Section 8, which provides the federal government with the power to call forth (i.e. federalize) the state militias for, amongst other things, the suppression of domestic insurrection.Footnote 77 However, even if one thinks the insurrectionist view overstated, or rejects it outright, the fact that citizens would remain armed even in the event of the federalization of the militias should act as a powerful constraint against government overreach. As Deudney notes, “the Constitution did not legalize rebellion, but it did legalize the instruments necessary to do so.”Footnote 78 Under Article 1, Section 8, the federal government had the responsibility to organize, arm, and discipline the militias. However, the states would be free to keep up an armed population if the federal government chose to neglect the militias.Footnote 79 Dunlap writes, “the Second Amendment reflects the Framers’ desire to ensure that the federal government could never deprive the state of sufficient armed manpower … the people would not be obliged to seek weapons from a federally-controlled armory, instead they would equip themselves.”Footnote 80 Indeed, the Uniform Militia Act, adopted less than a year later, required militia-eligible men to acquire weapons for this purpose. The states would retain a counterbalancing force even if the federal government sought to deprive them of one.
Where the Constitution increased the power of the federal government, the Bill of Rights acted to constrain it by enumerating separate individual and state rights.Footnote 81 The Second Amendment, however, is singular in that it appears, on its face, both as an individual right (“the right of the people to bear Arms, shall not be infringed.”)Footnote 82 and as a state right (“A well regulated Militia”), fueling the ongoing debate between Standard Modelers and collective-rights advocates.Footnote 83 However, both sides agree that the Second Amendment was intended to ensure that the newfound republic would not succumb to arbitrary rule (amongst other things). In other words, the Second Amendment is a check on federal power, in particular its coercive power, that helps ensure that the republic remains free (“the security of a free state”). In game-theoretic terms, the Second Amendment helped mitigate the prevailing commitment problem in several ways. First, it diminished the need for a large standing federal army, which could be used for the purposes of domestic repression. Second, it created a counterbalance to the federal army in the form of the state militias and an armed population.Footnote 84 The right to bear arms diffused the power of the federal government by putting the entirety of the coercive apparatus beyond its control. Finally, in the most extreme interpretation, the Second Amendment provided the right to confront a tyrannical government by force. In so doing, the Second Amendment helped alter the prevailing incentive structures, reducing the incentive to defect by devolving the coercive power of the federal government, in both absolute and relative terms, to the states.Footnote 85 A weaker federal government would be less capable of tyrannizing the states, particularly if counterbalancing forces largely independent of the federal government were maintained.
From a game-theoretic perspective, then, an armed population should have a deterrent effect on the abuse of power.Footnote 86 In guaranteeing a right to bear arms, the states enlisted a strategy of self-enforcement to overcome their fear of defection. Unlike the other checks and balances, the Second Amendment allowed the states themselves to enforce the bargain struck in confederation. By maintaining their own counterbalancing coercive apparatus in the form of an armed citizenry, the states needed not rely exclusively on a third party, such as the Supreme Court, to keep the federal government in check.
In this sense, the Second Amendment is not simply a continuation of colonial arrangements, in which a militia – drawn from and comprising the population – ensured the internal security of the colonies.Footnote 87 Nor did it rest on the assumption that citizen–soldiers were expected to fight better than professional soldiers against external threats. The Second Amendment was a radical innovation designed to prevent the new government from squelching the liberty of the republic. Weapons, then, were not so much an alternative to the other Constitutional checks and balances, as they were an insurance policy against their failure, allowing the states to take the risks necessary to construct a more robust republic.Footnote 88 Coupled with the other limits in the Constitution,Footnote 89 and the cumbersome process required to federalize the militias, the result was a central authority with little capacity to assert its writ without the consent of the governed.
Indeed, the states as well as individual citizens have, on several occasions, used their independent coercive power to defy the federal government.Footnote 90 In at least two examples – the disputed presidential election of 1800Footnote 91 and the Nullification Crisis of 1832Footnote 92 – the threat of a violent confrontation between state and federal governments helped motivate the leadership to reach a compromise, thus defusing the situation. Armed uprisings are messy affairs and are, therefore, best avoided. Whether or not such examples qualify as unwise, illegitimate, or even treasonous is beyond the scope of this paper. What is certain is that had there been no Second Amendment, such examples of the states counterbalancing the federal government by force would scarcely exist.
At the end of the Revolutionary War the federal government largely demobilized its military, “save 80 men to guard the stores.”Footnote 93 While proposals to strengthen the federal army were repeatedly presented, most notably by George Washington, who argued that the militias underperformed during the Revolutionary War, the new federal military remained underfunded and anemic. Despite being granted the authority to raise an army under Article I, Section 8, of the Constitution, the federal government took little interest in doing so. The poor economic health of the new country, distrust of standing armies, and long-standing faith in the militias at first precluded the development of a strong national force. The government instead relied on the patchwork of state militias to confront security threats, both at home and abroad. However, these too had mostly fallen into a state of disrepair. Persistent bickering between the federal government and the states over whose responsibility it was to pay for the militias led most states to neglect them.Footnote 94
Over time, domestic and international threats would give rise to the need for a more robust centralized coercive apparatus. The Militia Act of 1792, passed in response to the Shays Rebellion, made it considerably easier for the President to call forth (i.e. federalize) the state militias to suppress domestic unrest.Footnote 95 And, by the end of the Second World War, the US had amassed amongst the most powerful standing national armies in the world. “As war became total in intensity and global in scope,” Deudney explains, “constraints on the central state were weakened and compromised in the rush to mobilize and coordinate the economy and populace … the need for grand strategic and civil–military integration conflicted with the elaborate system of constraints upon executive war-making.”Footnote 96 As a result, the United States has gradually come to more closely resemble other states with a centralized coercive apparatus (i.e. a monopoly over the use of force). Deudney concludes that this was “probably inevitable” given the threats posed by opponents of the United States. In this way, the United States offers an example of institutional isomorphism.Footnote 97
CONCLUSION
The purpose of this paper has not been to overstate the role of the Second Amendment in the founding of the United States. Instead, it has been to shed light on one of its more unusual aspects. Unlike other in countries, the Second Amendment created an oligopoly over the use of force. Various interpretations have been offered on how the Second Amendment would help mitigate the monopolization of power: the strong variant holds that an armed citizenry would have the means to overthrow the government should it exceed its authority, thus providing a powerful disincentive for federal overreach. The weak variant holds that the militias counterbalance the power of the federal government and limit the necessity of a strong centralized army with which the federal authorities might interfere in the workings of the states.
In exploring this peculiar feature of the Constitution from a game-theoretic perspective, the paper helps partially reconcile Standard Modelers with those who view the Second Amendment as a collective right. In game-theoretical terms, the Second Amendment can be viewed as a (partial) solution to the credible-commitment problem. It not only limits federal power by preventing the federal government from disarming state militias; it also constrains the federal government by providing a counterbalancing force, thereby disincentivizing defection. In both readings, the right to bear arms provides a self-enforcement tool against the potential defection of the federal government. Unlike other checks and balances, the Second Amendment allowed the states to enforce the Constitutional bargain themselves. As such, the Second Amendment helped create a measure of certainty in the uncertainty of the Revolutionary period. Though considerably less important than other checks and balances, the novelty of the Second Amendment makes it a worthy subject of study.
As the Revolutionary period passed, the states let their militias decline; over time, the coercive apparatus has coalesced in the hands of the federal government, growing in size and strength. Nevertheless, the right to bear arms remains as a lingering feature of the states’ fear of arbitrary and coercive authority. Though individuals and the states have, on occasion, used the coercive power afforded them by the Second Amendment against the central government (sometimes illegally), what is remarkable is how rare these incidents are. The republic has held together not by some centripetal force, but instead through its unique system of power sharing and checks and balances, which include the Second Amendment.
