Hours after Iran announced that it had shot down a U.S. drone, President Trump told journalists at the White House, "You'll soon find out" if the U.S. is planning a strike on Iran in retaliation.
"They're going to find out they made a very big mistake," Trump added, in comments that came as he met with Canadian Prime Minister Justin Trudeau.
But Trump also said he suspects that Iran's taking out the drone was not intentional, saying he finds it hard to believe.
