Abstract

Scholars have long debated the relative influence of domestic and international factors on the presidential use of force. On one matter, however, consensus reigns: the U.S. Congress is presumed irrelevant. This presumption, we demonstrate, does not hold up to empirical scrutiny. Using a variety of measures and models, we show a clear connection between the partisan composition of Congress and the quarterly frequency of major uses of force between 1945 and 2000; we do not find any congressional influence, however, on minor uses of force. We recommend that the quantitative use-of-force literature in international relations begin to take seriously theories of domestic political institutions, partisanship, and interbranch relations that have been developed within American politics. a
