President Trump should have never dragged the United States into war with Iran in the first place, and the American people have paid the price for the dumbest foreign policy decision in a generation. Fourteen brave servicemembers were killed and hundreds more have been injured, families have suffered higher gas and groceries bills, and countless innocent civilians, including children at an Iranian school for girls, were killed. I am glad the conflict has halted as the result of negotiations. But no one in the Trump administration or his Republican enablers in Congress–who repeatedly voted to continue military action–can explain how people in Massachusetts and across our nation are safer or better off because of the war. Trump’s war is a failure by his administration's own metrics: Iran is now a more extreme regime with greater leverage over the Strait of Hormuz. I hope this deal means his war is over. The only way to prevent Iran from having a nuclear weapon is through a diplomatic agreement–which Trump ripped up, went to war instead, and then negotiated worse terms. The burden is now on the Trump administration to inform Congress and the public on the details of the U.S.-Iran deal, explain its sanctions approach, and ensure we end this destructive and costly war.(Elizabeth Warren)
