Trump quips about Pearl Harbor when asked if Japan given advanced notice on Iran attacks: 'Wanted surprise'

President Donald Trump made a quip about Pearl Harbor Thursday when asked if Japan and other American allies were given advance notice about attacking Iran, saying the U.S. "wanted surprise." 

Trump made the comment while sitting across from Prime Minister of Japan Sanae Takaichi during a bilateral meeting at the White House. 

"Japan and the U.S. are very good friends, but one question, why didn't you tell U.S. allies in Europe and Asia, like Japan, about the war before attacking Iran? So we are very confused about, we Japanese citizens," a reporter asked Trump. 

"Well, one thing, you don't want to signal too much," the president responded. "You know, when we go in, we went in very hard, and we didn't tell anybody about it because we wanted surprise. Who knows better about surprise than Japan? Okay? Why didn't you tell me about Pearl Harbor? Okay? Right?"

"You know, he's asking me, ‘Do you believe in surprise?’ I think much more so than us. And we had to surprise them. And we did," Trump continued. "And because of that surprise, we knocked out the first two days, we probably knocked out 50% of what we — and much more than we anticipated doing. So, if I go and tell everybody about it, there's no longer a surprise, right?"

Earlier in the meeting, Trump told reporters, "We're doing this excursion. And when it's completed, we're going to have a much safer world. And the Prime Minister agrees with me on this."

"Iran is a serious threat to the world, to the Middle East and to the world. And everybody agrees with me," Trump said. "I think virtually every country agrees with me on that. So I wanted to put out that fire."
