Source-derived summary

The "Day of Infamy" speech, sometimes referred to as the Infamy speech, was a speech delivered by Franklin D. Roosevelt, the 32nd president of the United States, to a joint session of Congress on December 8, 1941. The previous day, the Empire of Japan attacked United States military bases at Pearl Harbor and declared war on the United States and the British Empire. The speech is known for its famed first line, which opened with Roosevelt saying, "Yesterday, December 7, 1941—a date which will live in infamy..."

On Sunday, December 7, 1941, the United States Navy base at Pearl Harbor in the Territory of Hawaii was attacked by 353 Imperial Japanese Navy Air Service aircraft in a surprise military strike, destroying various American ships and aircraft, and killing over 2,400 civilians and military personnel. After consulting his cabinet, Roosevelt decided to deliver an address before the joint session of Congress the next day.

Roosevelt's speech was worded to reinforce his portrayal of the United States as a victim of unprovoked Japanese aggression and appealed to patriotism rather than to idealism. Roosevelt's choice to speak promptly helped make the speech rhetorically powerful. According to author Sandra Silberstein, the speech followed a well-established tradition of how "through rhetorical conventions, presidents assume extraordinary powers as the commander in chief, dissent is minimized, enemies are vilified, and lives are lost in the defense of a nation once again united under God".

The speech had an immediate positive response and long-lasting impact. It is one of the most famous speeches of American politics. It was broadcast live by radio and attracted the largest audience in American radio history, with over 81% of adult American listeners tuning in to hear the speech.
