The Iran nuclear deal is not a moment for euphoria but a moment for cautious optimism, said Carnegie’s Karim Sadjapour on CNN. While the deal provides minor sanctions relief and unfreezes about 10 billion dollars’ worth of Iranian assets, the reality is that if six months from now Iran decides to renege on some of the agreements, the sanctions will remain intact. “If it took marathon diplomacy to reach only an interim deal, to reach a final resolution to this conflict, it’s going to resemble an ultra-marathon through mine fields,” Sadjapour explained. “It’s going to be very difficult to reach a final resolution.”

“We have to have realistic expectations about what this deal is. The United States and Iran are not going to be allies tomorrow. The United States, Saudi Arabia, and Israel are going to remain allies,” Sadjapour noted. “This is very much potential nuclear détente. We are not on the verge of a U.S.-Iran rapprochement.”
