President Trump says he will unilaterally reinstate international sanctions on Tehran, after the U.N. Security Council rejected a U.S. resolution to extend the embargo on Iran. Trump plans to claim the U.S. is still technically a “participant” in the 2015 Iran nuclear deal — even though Trump himself withdrew from it — and can therefore order an extension of sanctions if Iran violates the deal. Iran called the U.N. vote a humiliating defeat, and European countries expressed doubt as to whether Trump can unilaterally force such measures.
