What were the superpowers in WW2?

During World War II, the primary superpowers were the United States, the Soviet Union, the United Kingdom, and China, collectively known as the Allies. They opposed the Axis powers, which included Germany, Italy, and Japan. The U.S. and the Soviet Union emerged as the dominant global superpowers by the war's end, leading to a significant shift in international relations and the onset of the Cold War. The conflict fundamentally reshaped political, economic, and military dynamics worldwide.
