Republican presidential candidate Donald Trump said on Sunday that the Iran nuclear deal concluded in Vienna last month will result in a nuclear Holocaust.

“They are going to be such a wealthy, such a powerful nation, they are going to have nuclear weapons,” the 2016 hopeful said of Iran in an appearance on NBC’s Meet the Press. “They are going to take over parts of the world that you wouldn’t believe. And I think it’s going to lead to nuclear Holocaust.”

The bombastic business tycoon went on to describe the negotiators of the accord, including Secretary of State John Kerry “and his friends,” as “incompetent.”

In contrast to other Republican candidates, Trump told Meet the Press host Chuck Todd that he wouldn’t discard the nuclear deal on day one of his presidency, but, he said, he would “police that contract so tough that they don’t have a chance, as bad as the contract is. I will be so tough on that contract.”

If Congress votes next month to reject the nuclear accord, Iran will still receive billions in funds that were formerly frozen and unavailable to the regime, Trump pointed out. He said the windfall will put Israel in harm’s way and slammed President Obama for allowing Israel to face such threats.

“Iran is going to be unbelievably powerful, and unbelievably rich and Israel is in big trouble,” he said. “Israel is in big trouble. Obama has really let Israel down.”
