He revealed this in a tweet on Friday.
The US had planned attacks on three sites in Iran in response to the shooting down of an unmanned American drone.
He noted that he called off the attacks because he was told 150 people would die if he didn’t.
His tweet reads:
“10 minutes before the strike I stopped it, not proportionate to shooting down an unmanned drone”.
“I am in no hurry. Our military is rebuilt, new, and ready to go, by far the best in the world
