Final answer:
FDR indeed referred to December 7, 1941, as "a date which will live in infamy" in his speech requesting a declaration of war from Congress, a statement which is true.
Step-by-step explanation:
The statement that Franklin D. Roosevelt referred to December 7, 1941, as the date Japan surprise attacked the U.S. fleet in Pearl Harbor when requesting a declaration of war from Congress is true.
President Roosevelt delivered his famous "Day of Infamy" speech to a Joint Session of Congress on December 8, 1941, the day after the Pearl Harbor attack. In this speech, he condemned the attack by Japan as "a date which will live in infamy," and called on Congress to issue a declaration of war against Japan. The United States Congress responded quickly, formally declaring war on Japan, and therefore entering World War II. Shortly thereafter, Germany and Italy, Japan's allies, declared war on the United States, cementing the U.S. engagement in the global conflict.
