The day after the attack, President Roosevelt's delivered his "date which will live in infamy" speech to a Joint Session of Congress. He said: "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."
That day, Congress voted to declare war against Japan.
