who won ww2

World War II was won by the Allied powers, which included the United States, the United Kingdom, and the Soviet Union, among others. The victory was a collective effort of these nations against the Axis powers led by Germany, Italy, and Japan. The Soviet Union played a crucial role on the Eastern Front by inflicting massive losses on the German military, while the US and UK contributed heavily through industrial capacity, military campaigns in Western Europe, and the Pacific theater. The war ended in Europe with Germany's unconditional surrender on May 8, 1945, and in the Pacific with Japan's surrender in August 1945 after atomic bombings and military defeat.
