How did the United States enter World War II?
The United States resisted entering World War II until the attack on Pearl Harbor, December 7 1941. While the citizenry and media were openly (if not overtly) hostile towards Germany and Japan, the Roosevelt administration took a deliberate position of neutrality, citing, among other things, expenditure of money and men during World War I; however, they did offer supply support to British forces as well as Naval enforcement of ocean borders. However, with the surprise attack on Pearl Harbor, the U.S. officially entered the war as a supported of the Allied Forces. The U.S. Military needed increased numbers and training because of lax policies after WWI, and the War Effort in the U.S. became the primary drive of both the economy and the culture for the next four years.
