Over the past few years, a loose coalition of activist groups, think tanks, and policy-makers dedicated to ending the post-9/11 forever war has asserted itself in foreign policy debates. As recently as February, when Bernie Sanders appeared to be the front-runner for the Democratic presidential nomination, it seemed possible that US foreign policy was on the verge of turning toward a less militarized and interventionist approach. Sanders and the other major progressive candidate in the race, Elizabeth Warren, had foreign policy advisers who advocated slashing defense budgets and reinvesting in diplomacy to confront nonmilitary threats.
