Earlier in the week, Graham criticized his presidential rival, former Arkansas Gov. Mike Huckabee (R), for using a Holocaust analogy to criticize the same deal.
"I don't question President Obama's motives. That's where Mike has gone down the wrong road," Graham said at the time. "I like Mike Huckabee, but this is about the most sensitive subject matter I can imagine."
But during his Thursday interview on Newsmax TV's "The Steve Malzberg Show," Graham went with a Hitler reference anyway.
"The Munich deal would have made sense if Hitler just wanted German-speaking people under the German umbrella. Munich partitioning Czechoslovakia, and giving him more power and reenforcing his belief that the West was weak, was a terrible deal. He in fact, wanted to kill the Jews and have a master race," Graham told the Newsmax host. "This is a bad deal because the Ayatollah gets more money and more weapons and a clearer path to the bomb. Here’s what the deal does: It gives him a bomb, a missile to deliver and the money to pay for it. What would he do with a missile and the bomb? Does he feel compelled by his religion to attack Israel and destroy democracies like ours? I say yes."
