President Donald Trump is expected to pull the United States out of the Iran nuclear agreement on May 12. Tehran signed the Joint Comprehensive Plan of Action, with China, France, Germany, Russia, Britain, and the United States in 2015.
Iran agreed to curbs on its nuclear program in exchange for the lifting of some sanctions. But the withdrawal of the United States will probably sink the deal. If that happens, Iran could retaliate by undermining the interests of Washington and its allies in the Middle East.
