Iranian Foreign Minister Javad Zarif warned that the Iranian nuclear deal would be dead if the U.S. Congress imposes new sanctions, even if they do not take effect for six months, Time Magazine said on Monday. According to the magazine, he replied: "The entire deal is dead." Zarif was referring to a November 24 interim agreement with six world powers under which Tehran would curb its nuclear program in exchange for limited relief from economic sanctions over the next six months. Zarif's comments had little effect on U.S. Senators who are preparing legislation to impose new sanctions on Iran in six months if the deal reached in Geneva goes nowhere. The Democratic chairman of the Senate Foreign Relations Committee, Robert Menendez, and Republican Senator Mark Kirk are close to agreeing on legislation that would target Iran's remaining oil exports, foreign exchange reserves and strategic industries, aides said on Monday.
