Answer:
The "Day of Infamy" speech refers to the address delivered by U.S. President Franklin D. Roosevelt on December 8, 1941, the day after the Japanese attack on Pearl Harbor. In this speech, President Roosevelt famously declares December 7, 1941, as "a date which will live in infamy." The speech is a call to Congress to declare war on Japan and marked the United States' entry into World War II.
