WASHINGTON (AP) — The U.S. and Iran stepped back from the brink of possible war Wednesday, as President Donald Trump indicated he would not respond militarily after no one was harmed in Iran’s missile strike on two Iraqi bases housing U.S. troops. Trump says Iran appeared to be “standing down. The Iranian strikes had come days after Trump authorized the targeted killing of Gen. Qassem Soleimani, the head of Iran’s elite Quds Force. Trump said Americans should be “extremely grateful and happy” with the outcome. Speaking from the White House, Trump announced that the U.S. will immediately place new sanctions on Iran “until Iran changes its behavior.”
