Israelis wouldn't have to be marched to ovens. The ovens would come to them. They would come in the form of an atomic bomb, which burns hotter than an oven.
On today's Morning Joe, Eugene Robinson said that he was "offended" by Mike Huckabee's remark that President Obama's Iran deal would "take the Israelis and march them to the door of the oven." Huckabee said the comment runs counter to the purpose of Israel, which is that "nobody is going to be marched towards any ovens."
