President Obama hit back at Mike Huckabee this morning, calling the former Arkansas governor's remarks on the Iran nuclear deal "ridiculous."

Huckabee invoked the Holocaust this weekend to argue that the agreement is dangerous for Israel's security. 

“This president’s foreign policy is the most feckless in American history,” Huckabee said in an interview with Breitbart News.

“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.”

Huckabee made similar criticism in an interview on Fox and Friends Saturday, saying that one nuclear attack by Iran could "can kill six million Jews."

Obama, speaking at a news conference in Ethiopia, responded by lamenting the harsh rhetoric coming from Republicans. 

“The particular comments of Mr. Huckabee are, I think, part of just a general pattern that we’ve seen that would be considered ridiculous if it weren’t so sad,” Obama said.

He surmised that maybe Huckabee was trying to push Donald Trump "out of the headlines," but said that it is not the kind of leadership America needs right now.

“I mean, we’ve had a sitting senator call John Kerry Pontius Pilate. We had a sitting senator who also happens to be running for president suggesting that I’m the leading state sponsor of terrorism. These are leaders in the Republican party," said Obama. 

The president said that in the past, American politicians did not resort to these types of statements on issues of "war and peace."

“Part of what, historically, has made America great is particularly when it comes to foreign policy, there’s been a recognition that these issues are too serious, that issues of war and peace are of such grave concern and consequence that we don’t play fast and loose that way," said Obama.
