Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945) also known by his initials, FDR) was the 32nd President of the United States and a central figure in world events during the mid-20th century, leading the United States during a time of worldwide economic crisis and world war. The only American president elected to more than two terms, he forged a durable coalition that realigned American politics for decades.
As World War II loomed after 1938, with the Japanese invasion of China and the aggressions of Nazi Germany, FDR gave strong diplomatic and financial support to China and Britain, while remaining officially neutral. His goal was to make America the "Arsenal of Democracy"—supplying the munitions while others did the fighting. In March 1941, Roosevelt, with Congressional approval, provided Lend-Lease aid to the countries fighting against Nazi Germany with Great Britain. He secured a near-unanimous declaration of war against Japan after the Japanese attack on Pearl Harbor on December 7, 1941, calling it a "date that will live in infamy".
