The United States implemented its first peacetime military draft through the Selective Training and Service Act, requiring all men aged 21-45 to register for potential military service. This historic decision strengthened America's military capabilities before entering World War II.
The United States implemented its first peacetime military draft in September 1940, more than a year before the bombing of Pearl Harbor. This historic decision came through the Selective Training and Service Act, which required all men between ages 21 and 45 to register for potential military service.
As World War II raged across Europe and Asia, President Franklin D. Roosevelt recognized the growing need to strengthen America's military capabilities. The draft initially called for 900,000 men to serve for one year, marking a significant shift in U.S. military preparation strategy. By the time Japan attacked Pearl Harbor on December 7, 1941, the draft system was already well-established and ready to support America's full entry into World War II.
