And War Wasn't Even A Certainty

But the President actually did it right back then. He asked for a declaration of war. He just didn't go do it.

"I ask that the Congress declare that since the unprovoked and dastardly attack by Japan on Sunday, December 7th, 1941, a state of war has existed between the United States and the Japanese empire."

(Congress has never declared war on Iraq or Afghanistan.)

Edit: Some of you need to read one of the headlines.
