About this source
What it is
This is the speech President Franklin D. Roosevelt delivered to a joint session of Congress on December 8, 1941, the day after the Japanese attack on Pearl Harbor. The U.S. National Archives holds the typed draft, which shows Roosevelt's own handwritten edits, including his change of the opening line to call December 7 'a date which will live in infamy.'
Why it matters
The attack killed and wounded thousands of Americans and shocked the nation. Roosevelt dictated the speech himself rather than accepting a longer draft proposed by Secretary of State Cordell Hull, choosing a short, direct appeal. Congress responded almost unanimously by declaring war, and the United States entered World War II that same day.
Look closer
- Why do you think Roosevelt changed 'world history' to 'infamy' in the opening line?
- What can the handwritten edits on the draft tell you about how speeches are made?
- Why might Roosevelt have chosen a short, simple speech instead of a long explanation?
