While the Japanese attack on Pearl Harbor (December 7, 1941) is recognized as the event that caused the United States to join the war, it is not as widely known that America was engaged in a massive rearmament program, provided military aid to the British and their allies and generally provoked German, Italian and Japanese retaliation before their official entry into the war.

June 13, 1940: The first surplus stocks of American rifles and artillery weapons were shipped to the UK in response to prior requests made by Churchill to Roosevelt during the Battle of France. The Neutrality Act was circumvented by first selling the arms to a steel company and then reselling them to the British government.

January 29, 1941: Secret staff talks began in Washington between British and American representatives. One of the results of these talks, which continued until March 27, 1941, was agreement that defeat of Germany should receive priority in the event of a war with both Germany and Japan.
