The main objective of the Allied forces in World War II was the unconditional surrender of the Axis powers, primarily Germany, Japan, and Italy. The Allies aimed to defeat these nations to restore peace and security, as well as to address the widespread atrocities committed during the war. Key strategic decisions included collaborating on military operations, engaging in major battles, and coordinating economic resources. Significant milestones toward achieving this objective included the D-Day invasion in 1944 and the use of atomic bombs on Japan in 1945. The Allies’ victory culminated in the establishment of a new world order and paved the way for international peacekeeping efforts.
