Comedy from Henry Farrell in 2007.

The paper tries to answer the question of why America invaded Iraq and, more broadly, what the invasion of Iraq says about America’s strategic position, foreign policy choices and public opinion over foreign policy. Snyder, Shapiro and Bloch-Elkon (henceforth S,S,B-E for convenience) argue that one needs to understand both international and domestic factors in order to answer this question. Unipolarity – the US’s unchallenged position as the most powerful state in the international system – explains why the US could consider engaging in imperial policies.

that also... means that the crazies are much less likely to exert meaningful political influence than they were in 2001-2004.
