President Franklin Delano Roosevelt gives his famous speech to Congress following the Japanese attack on Pearl Harbor. At the end of his speech, he asks Congress to declare war against Japan, which officially brings the United States into World War II.
The three world leaders Joseph Stalin, Winston Churchill, and Franklin Roosevelt come together during the Yalta Conference to decide how Germany will be defeated, divided and punished.
