Hyperbolic analogies to Nazis or the Holocaust are hardly a new feature of American political rhetoric, but Republican presidential candidate Mike Huckabee got weirdly specific about concentration-camp crematoriums yesterday when denouncing the Obama administration’s nuclear deal with Iran. In a Breitbart interview, Huckabee declared, “This president’s foreign policy is the most feckless in American history. It is so naive that he would trust the Iranians. By doing so, he will take the Israelis and march them to the door of the oven.”
