George Packer believes foreign policy will largely define it:
If Obama loses—a possibility that’s become the wisdom of the week—I think he’ll be remembered most for his foreign-policy achievements. And if he wins, the same will be true, except that he’ll have a chance of being a great foreign-policy President. [Ben Rhodes, speechwriter and deputy national security advisor] is right: foreign policy defines every President more than he expects coming in, and it does so in completely unexpected ways. It’s both more out of the President’s control than domestic issues and more under his control. It’s played to all of Obama’s strengths. In this sense, a one-term Obama Presidency would look less like the one that’s often held up as a spectre of failure, Jimmy Carter’s, and more like the one that’s increasingly considered a success, that of George H. W. Bush, the living President about whom Obama has had the most nice things to say.
My support for Obama is primarily because of foreign policy. And thus far, he has exceeded my expectations.
