Franklin D. Roosevelt was the 32nd president of the US. Before WWII, he dealt with the Great Depression and its economic impact. On December 7, 1941, Japan attacked Pearl Harbor, killing over 2,000 US soldiers and injuring 1,000 more. This prompted Roosevelt to declare war on Japan. The Atlantic Charter was an agreement between Roosevelt and Winston Churchill that outlined a vision for the post-war world, including disarmament and freedom from fear.
