Choosing to Intervene: US Domestic Politics and Moral Imperatives

The end of the Cold War meant fewer constraints on humanitarian intervention, and the third pillar of the nascent R2P norm suggests at least a moral imperative to intervene when another country's population is threatened. Yet US leaders continue to shy away from protecting innocents outside of the United States from harm - despite the fact that presidential candidates often campaign on restoring America's moral lead in the world and, in particular, on US responsibilities to avert mass atrocities. This paper investigates the extent to which US military intervention abroad is driven by domestic considerations. Using logistic regression analysis, we aim to explain decisions by Presidents Bush Sr., Clinton and Bush Jr. to send troops into harms way.
