When the leaders of the world's richest nations gather in Evian, France, one unasked question will dominate: what does America want in the world? So it may be helpful to outline the principles and ideas that guide US foreign policy.
First, inconsistency is no vice. Indeed, in foreign policymaking, inconsistency is often a virtue. I speak not of principles, but of policy. The US does not have a "one size fits all" approach to the world. What happened in Iraq should not be over‑interpreted as a rigid template for US policy toward countries that pursue weapons of mass destruction, support terrorism, or deny people liberty.
