What would be the Sanders Doctrine?

WASHINGTON, DC: Is Bernie Sanders a closet foreign policy “realist”? Reading his few pronouncements on foreign policy, you sense that he embraces the realists’ deep skepticism about American military intervention. But he has said so little about foreign policy that it’s hard to be sure.

Foreign policy is the hole in Sanders’ political donut. We know what he doesn’t like -- the 2003 invasion of Iraq, which he mentions, in nearly every debate, almost robotically, describing it as “one of the worst foreign policy blunders in the modern history of the United States.” But there’s far less clarity about what he does favor.
