President Barack Obama began his term defining his foreign policy very simply: Tone down the rhetoric of President George W. Bush, focus on humanitarian issues, and reduce American militarism. Analysts, commentators, and pundits have tried to codify this general approach into an Obama doctrine, a set of coherent ideas that define and explain the president's policies. Two years later, however, it's difficult to say what, exactly, Obama's doctrine actually is. It is even more difficult to see a departure from President Bush's foreign policy. None of this changes with Osama bin Laden's rather spectacular death in his mansion in Pakistan.
