President Trump said that Iran appears "to be standing down" after Tuesday night's missile attack in Iraq and that "the American people should be extremely grateful and happy no Americans were harmed."
Trump, in a nationally televised address from the White House, also announced a new round of what he termed "punishing economic sanctions" against the Iranian government. And he called on NATO to become "much more involved in the Middle East process."
