Iran will go back on the nuclear agreement it just signed with the United States and other world powers if Congress imposes new sanctions, Iran’s foreign minister told NBC News after the deal was announced.

“If there are new sanctions, then there is no deal. It’s very clear. End of the deal. Because of the inability of one party to maintain their side of the bargain,” Foreign Minister Javad Zarif said during an exclusive interview with NBC News…

Rep. Ed Royce, R-Calif., chairman of the House Foreign Affairs Committee, warned that the deal does not meet the standards necessary to protect the United States and its allies.

“Instead of rolling back Iran’s program, Tehran would be able to keep the key elements of its nuclear weapons-making capability. Yet we are the ones doing the dismantling – relieving Iran of the sanctions pressure built up over years,” Royce said in a statement.
