Mike Huckabee continues to reiterate and build on his controversial remark from earlier in the week when he said that President Obama's nuclear agreement with Iran "would take the Israelis and basically march them to the door of the oven."

In a Fox News interview Tuesday, that included a split-screen of Neville Chamberlain and Barack Obama, Huckabee said that when he was at Auschwitz and saw the oven door, 'He swore to God that I would not stand by and let it happen again.'

"I think we underestimate the radical nature of these animals who run Iran," Huckabee added. "Anything is better than allowing these terrorists to have nuclear capacity."
