President Barack Obama said that the Iran nuclear deal met the national security interests of the United States and its allies. According to him, Iran obtaining a nuclear weapon could be “the most serious threat.” He heavily defended the nuclear deal during a press conference Wednesday, telling reporters at the White House that the deal had made the country and the world safer and more secure.

"It is incumbent on the critics of this deal to explain how an American president is in a worse position -- 12, 13, 14, 15 years from now -- if, in fact, at that point, Iran says, 'We're going to back out of the (deal), kick out inspectors and go for a nuclear bomb,'" CNN quoted the U.S. president, who demanded a better solution from the critics of the nuclear deal.

While Obama was aware that he is going to face a debate on the deal at Congress, he said that he expected a “robust” debate. American lawmakers have been deeply skeptical about the nuclear deal and its effect on the political situation in the Middle East.

New York Democratic Rep. Steve Israel said that he would use the 60-day review period to decide if he should support the Iran deal. He said that he had been skeptical about the deal since the very beginning. “I read the Joint Comprehensive plan of action last night, and there was nothing in it to relieve my skepticism,” NBC News quoted Israel.

Obama indicated that he was open to any form of conversation regarding the issue. During the press conference, the U.S. president said that his goal was to make sure that Iran did not achieve a nuclear weapon.
