The speech was before the U.S. Congress, in Washington, D.C., December 8, 1941. Background: The President of the United States does not have the power to "declare war." The U.S. Constitution reserves that power to the Congress. As Commander in Chief, the President has some powers -- or has assumed some powers -- to use military action, but a "declaration of war" is in the hands of the Congress. In that famous speech, FDR asked Congress for a declaration of war: "I ask that the Congress declare that since the unprovoked and dastardly attack by Japan on Sunday, December 7th, a state of war has existed between the United States and the Japanese Empire." When Congress issued the declaration, FDR, as President, signed it.
The Potsdam Declaration warned Japan that if it did not surrender it would face "prompt and utter destruction".
