Chapter 13 synthesizes the book’s core claim: American constitutional war powers are not a single “start” switch but an interlocking system of authorities that shapes whether wars occur, who fights them, how and where force is used, how war aims evolve, and how wars end. It outlines how a possible future war with China would involve or test all of these powers. The chapter argues that powers to initiate hostilities are inseparable from powers for organizing forces, posturing and threatening, setting objectives, funding, oversight, and defining the terms of peace. It reframes the “imperial presidency” narrative by showing that while presidential initiative has expanded, Congress’s capacities have grown as well – especially through force-building, appropriations, and peacetime institutional design – and that many of the most consequential shifts were joint. It explains why originalism is inadequate: later military capacity, alliances, covert action, and technology forced constitutional accommodations the Founding generation could not specify. At the same time, it rejects the view that war-powers law is merely politics or necessity, emphasizing how law constrains strategy. Finally, it argues that durable reform lies less in rigid restrictions on the use of force than in strengthening Congress’s strategic guidance and oversight, especially as future conflicts further blur the line between peace and war.

Chapter 1 asks how the Framers thought about war and security – and how those concerns shaped the Constitution’s approach to military power. It shows that the Constitution does not vest a single, all-purpose “war power” in any one branch. Instead, it divides authority horizontally among Congress, the President, and the courts, and vertically between the national government and the states. These choices reflected anxieties about executive overreach, legislative inertia, standing armies, and the domestic dangers of concentrated military power, alongside a desire to preserve state control over local defense and militias. They also reflected differing views and assumptions about American grand strategy. Drawing on Convention debates, ratification-era writings, and early commentary, the chapter explains how war powers were distributed across multiple functions, including creating and organizing forces, going to war, commanding operations, regulating military conduct, deploying troops domestically, and deciding how wars end. This multidimensional design aimed to prevent any single institution from dominating military power while still enabling effective national defense. In doing so, the Founding settlement established a system of shared control grounded in institutional rivalry, overlapping authority, and political accountability rather than rigid rules.

This book reframes U.S. constitutional war powers by looking beyond the familiar question of which branch may start a conflict. Conventional accounts focus on moments when U.S. forces enter combat – most notably President Truman’s decision to fight in Korea without congressional approval in 1950 – and treat those episodes as the central test of constitutional limits. This book argues that such moments capture only part of how war powers operate in practice. Decisions to go to war are rarely isolated acts; they are shaped by earlier choices about force structure, troop deployments, alliances, and threats, often made jointly by Congress and the Executive. The book opens by pairing Truman’s Korea intervention with a less examined but equally consequential decision: the stationing of large U.S. forces in Western Europe to deter Soviet aggression. That peacetime deployment sparked constitutional debate and helped establish practices that continue to underpin American alliances. From there, the book traces how war powers evolved alongside American strategy from the early republic through the Cold War, the Global War on Terror, and today’s security challenges. Rather than offering a fixed constitutional formula, the book treats war powers as an adaptive system shaped by law, strategy, and institutional practice.

The epilogue, written in late 2025 during the opening year of Donald Trump’s second term, reflects the unease of finishing a book on war powers as presidential authority is asserted aggressively at home and abroad. Trump’s use of military force, emergency statutes, and National Guard deployments tests constitutional boundaries and revives fears – familiar to the Framers – that war powers can erode democratic self-government. Yet the epilogue resists both normalization and panic. By situating Trump’s actions alongside earlier episodes from Washington to Biden, it shows that many controversial uses of military power have precedents or precursors, even as red lines remain uncrossed. It emphasizes that constitutional checks often reemerge slowly – through legislation, litigation, and political pressure – and that their effects are often felt through the strategic environments created by the exercise of war powers.

Chapter 5 examines how the United States’ emergence as an overseas and imperial power at the turn of the twentieth century reshaped constitutional war powers, reinforcing the book’s claim that war powers are structured by strategic context and institutional practice. In the Spanish–American War, Congress’s power to declare war again proved a weak constraint; the central constitutional questions instead concerned expansion – who controlled the scope, geography, and ends of a conflict that quickly outgrew its initial justification. The chapter traces how presidential control over diplomacy, command, and military operations enabled decisions that transformed a limited war with Spain into an overseas empire, driven less by theories of unchecked executive power than by fast-moving military and geopolitical events beyond Congress’s reach. At the same time, the chapter challenges conventional accounts of presidential unilateralism by highlighting Congress’s most consequential role: sweeping legislative reforms of the Army and state militias. Statutes enacted between 1903 and 1916 fundamentally altered the federal–state balance of military authority by integrating the National Guard into the national war-powers system. Taken together, these developments demonstrate how American war powers adapted to imperial ambition through executive initiative abroad and legislative reengineering at home.

Considers whether Congress has any direct power to limit the scope of the president’s pardon power generally or in particular cases, and whether, if not, it might have some power to create procedural rules or administrative institutions that could improve the exercise of the presidential pardon power and its transparency.

Concludes that presidential pardon power should be abolished in its current form, either by removing pardon power entirely from the Constitution or conferring pardon power on Congress or giving Congress a veto over pardons. Contends that this should be done because pardons no longer serve their original purposes in the federal criminal justice system, because they should not be used as instruments of law reform, and because pardons have now been repeatedly proven to be dangerous to the constitutional rule-of-law order.

From the founding era to the turn of the twentieth century, Congress has at times asserted its power over elections robustly and creatively, even in periods of judicial obstruction, and its role in shaping the nation’s electoral landscape has always been pivotal – even when contested, uneven, or ineffective. This period invokes a rich and overlooked history that reveals a repository of federal authority over elections that was triggered (or ignored) less for reasons of federalism, and more so due to pragmatic, principled, or partisan considerations.

With Reconstruction in its death throes, Congress sporadically used its power under Article I, Section 5, to review the elections of its members and, in the process, police racial discrimination in voting, even though much of the disenfranchisement written in law was ostensibly race neutral. As illustrated in Chapter 9, Congress fought back against these disenfranchising regimes, which were adopted across the South over the course of the 1890s and set the tone for the exclusion of Black voters from American politics for almost a century. Congress’s efforts during this period bring this book back to a reoccurring theme: that political limitations, rather than constitutional constraints like federalism, were more of a barrier to the broad implementation of federal power over elections.

This chapter defines two key concepts in the book: “careerist bureaucrats” and “foreign affairs agencies.” After defining these terms, it traces the evolution of federal employees’ job protections in the United States over time and concludes that there is no longer a monolithic, one-size-fits-all merit system governing the contemporary federal civil service. The chapter then introduces variations in bureaucrats’ employment contracts within the civil service, outlining different classifications within both the federal bureaucracy and the foreign service. The president, Congress, and federal employee unions are presented as the three actors with vested interests in the design of these employment contracts. Based on this discussion, the chapter identifies three features that generate uncertainty in the employment contracts and thereby weaken bureaucratic job protections: removal, renewal, and conditional tenure.

This chapter explores the constitutional foundations, institutional role, and evolving powers of the United States Congress within the framework of separation of powers. Rooted in Article I, Congress holds enumerated powers such as taxation, spending, regulating commerce, and declaring war, but its authority is shaped by interactions with the executive and judiciary. Historical struggles between the British monarchy and parliament informed the Framers’ vision of legislative supremacy, tempered by checks against tyranny. The analysis focuses on four areas of congressional–executive conflict: delegation to regulatory agencies, appointment and removal powers, the impact of executive orders and signing statements, and investigatory and impeachment functions. Key Supreme Court cases – including Schechter Poultry, INS v. Chadha, Mistretta v. United States, and Bowsher v. Synar – illustrate how the Supreme Court mediates the limits of congressional authority. Although designed as the dominant branch, Congress’ ability to check the executive now depends on judicial interpretation, partisanship, and the challenges of the administrative state.

Richard L. Fox analyzes the historical evolution of women running for seats in the US Congress. The fundamental question he addresses is why women continue to be so underrepresented in the congressional ranks. Fox examines the experiences of female and male candidates for Congress by comparing fundraising totals and vote totals through the 2024 elections. While acknowledging the historic number of women candidates in 2022 and 2024, his analysis also explores the subtler ways that gender dynamics manifest in the electoral arena, examining regional variation in the performance of women and men running for Congress, the difficulty of change in light of the incumbency advantage, and gender differences in political ambition to serve in the House or Senate. The chapter concludes with an assessment of the degree to which gender still plays an important role in congressional elections and the prospects for gender parity in the future.

This chapter defends the nondelegation doctrine, arguing that the Constitution’s text, structure, and history prohibit Congress from delegating legislative power to the President or subordinate agencies. Textually, the Vesting Clause is an exclusive grant of legislative power to Congress and the Constitution omits any clause permitting delegation. Structurally, each branch is institutionally designed to performs its function effectively, a design disrupted if Congress cedes lawmaking authority to the executive. Historically, Madison’s warnings against power accumulation and other early statutes, discussions, and adjudications align with an “intelligible principle” or “important subjects” test, which refutes revisionist claims of broad delegations. The chapter critiques the Supreme Court’s lenient modern standard for upholding vague delegations, and proposes a reinvigorated doctrine requiring Congress to set major policies, preserving its deliberative function and preventing executive overreach.

From the founding of the Constitution, there has been a steady expansion of national power and an erosion of state powers. Notwithstanding the enumeration of its powers, Congress has enacted legislation impacting almost every aspect of American life. The Supreme Court has, with rare exceptions, accommodated the Congress’ intrusions on the powers of the state governments.

Failure to adequately constrain factions is reflected most prominently in partisan gridlock in Congress, Congressional abdication of constitutional authorities and responsibilities, the political divide in the appointment of federal judges, the perception of partisan influence on judicial decisions, and the growth of the administrative state.

Chapter 5 returns to discussions of the law at the federal level. It reconstructs debates over defunding the law in Congress and in the federal agencies, arguing that the Children’s Bureau leadership learned from their trouble administering Sheppard-Towner programs through the states. Giving states ultimate authority over programming had meant that each state director documented their Sheppard-Towner work differently – if they did so at all. When it came time to renew federal appropriations in Congress, the Bureau staff found itself unable to create and present national statistics on the workings of state programs. Children’s Bureau leaders recognized that they would have to take more control over state-level accounting in subsequent legislation if they hoped to maintain their claim to expertise through accurate reporting. In the meantime, without reliable national data, the Bureau had little ability to defend its use of federal dollars when conservatives swept Washington in the 1926 election and the law came under attack. A few years later, in a political climate much more friendly to federal intervention, the Bureau staff was able to implement the oversight they learned they needed in their administration of Title V of the Social Security Act.
