Trump Says He Stopped Iran Strike When Told 150 Would Likely Die

President Trump said the U.S. military was "cocked and loaded" to retaliate against Iran on three different sites Thursday night, but called off the operation after learning 150 people would likely die from the strike. Mr. Trump, explaining his decision on Twitter, said the response would have been "not proportionate to shooting down an unmanned drone."

As CBS News has reported, the president ordered the drone strike Thursday night, but backed down, avoiding — for now — a significant escalation of tensions between Iran and the U.S.
