Former Israeli ambassador to the United Nations Dan Gillerman reacted this afternoon to President Obama's latest speech touting the Iran nuclear deal. 

In an address at American University, Obama likened critics of the agreement to those who pushed for the invasion of Iraq more than a decade ago. 

"Many of the same people who argued for the war in Iraq are now making the case against the Iran nuclear deal," Obama said, declaring that every country in the world, except Israel, supports the deal. 

"The same mindset, in many cases offered by the same people - who seem to have no compunction with being repeatedly wrong - led to a war that did more to strengthen Iran, more to isolate the United States, than anything we have done before or since," the president said.

Gillerman said he believes the biggest applause and celebration tonight are coming from Tehran. 

"Here's the President of the United States, the greatest country on earth, the leader of the free world, apologizing for American foreign policy over the years," said Gillerman, questioning Obama's claim that every nation except Israel supports the deal. 

Gillerman said it's a fact that Israel is the only country that the Iranian regime has repeatedly threatened. He asked what will happen if Obama is wrong about Iran, arguing that Obama has been wrong previously on Iraq, Syria, Egypt and Libya.

"What if he's wrong? For him, it's another speech that maybe didn't go so well. For Israel, it's existential," he said. 

He acknowledged that Obama has a done a lot for Israel's security during his time in office, but if Iran goes nuclear, "then all that help will be of absolutely no use and Israel will be the target."

Gillerman called on the American people to listen to the Iranian regime when they say "death to America," talk about wiping out Israel and deny the Holocaust "while preparing the next one."
