Chile since the September 11 coup is a study in contrasts. There is the striking difference between the tensions and polarization of the last months of the Allende regime and the apparent calm and renewed sense of purpose of Chile under military rule. There is the contrast between the return to normalcy during the daytime and the repressive and chilling atmosphere during the nighttime curfew hours, when shots ring out periodically, helicopters fly overhead and armored cars patrol streets where only the occasional stray dog is moving freely.
