"President Trump announced the United States was "pulling out" of the Iran nuclear agreement Tuesday. As many have pointed out, the more accurate language would be that the U.S. violated the agreement, since we abandoned it without cause. There is no evidence at this point that Iran was in violation of the agreement by restarting its nuclear program. Our closest European allies have said as much, denouncing Trump's decision and declaring they will remain in the accord."
