Other major 1930s legislation and agencies implemented under Roosevelt include the Securities and Exchange Commission, the National Labor Relations Act, the Federal Deposit Insurance Corporation, Social Security, and the Fair Labor Standards Act.
Roosevelt was re-elected in 1940 for his third term, making him the only U.S. president to serve for more than two terms. By 1939 another World War was on the horizon which prompted the United States to respond by passing a series of laws affirming neutrality and rejecting intervention. Despite this, President Roosevelt gave strong diplomatic and financial support to China, the United Kingdom, and eventually the Soviet Union. Following the Japanese attack on Pearl Harbor on December 7, 1941, an event he called "a date which will live in infamy", Roosevelt obtained a congressional declaration of war against Japan. On December 11 Japan's allies, Nazi Germany and Fascist Italy declared war on the United States. In response, the US formally joined the Allies and entered the European theater of war.
