Trump: U.S. will respond with 'great force' if Iran attacks interests

President Donald Trump warned on Monday Iran would be met with “great force” if it attacked U.S. interests in the Middle East, and government sources said Washington strongly suspects Shi’ite militias with ties to Tehran were behind a rocket attack in Baghdad’s Green Zone. “I think Iran would be making a very big mistake if they did anything,” Trump told reporters as he left the White House on Monday evening for an event in Pennsylvania. “If they do something, it will be met with great force but we have no indication that they will.” His comments came as two U.S. government sources said the United States strongly suspects Shi’ite militias with ties to, and possibly encouragement from, Iran fired a rocket on Sunday into Baghdad’s heavily fortified Green Zone.
