World War II was won by the Allied powers, primarily including the United States, the United Kingdom, the Soviet Union, and their allies. The major countries on the losing side were the Axis powers, primarily Germany, Italy, and Japan. The war ended in 1945 with Germany surrendering in May and Japan surrendering in September following atomic bombings by the United States and the Soviet declaration of war against Japan.
The Allies included major powers like the UK, USA, Soviet Union, France, and to a lesser extent China, while the Axis was led by Germany, Italy, and Japan. The victory by the Allies shaped the post-war world, establishing the United Nations and the Cold War rivalry between the US and the Soviet Union.
In summary:
- Winners: Allied powers (USA, UK, Soviet Union, France, China, and others)
- Losers: Axis powers (Germany, Italy, Japan).
