International law presents a conceptual riddle. Why comply with it when there is no world government to enforce it? The United States has long history of skepticism towards international law, but 9/11 ushered in a particularly virulent phase of American exceptionalism. Torture became official government policy, President Bush denied that the Geneva Conventions applied to the war against al-Qaeda, and the US drifted away from international institutions like the International Criminal Court and the United Nations. Although American politicians and their legal advisors are often the public face of this attack, the root of this movement is a coordinated and deliberate attack by law professors hostile to its philosophical foundations, including Eric Posner, Jack Goldsmith, Adrian Vermeule, and John Yoo. In a series of influential writings they have claimed that since states are motivated primarily by self-interest, compliance with international law is nothing more than high-minded talk.
