The term "Western Allies" refers to the coalition of countries that opposed the Axis powers during World War II, primarily consisting of the United States, United Kingdom, and Soviet Union. These nations worked together to defeat the common enemy, which included Germany, Italy, and Japan. Their collaboration involved military strategies, resource sharing, and coordinated efforts on various fronts. After the war, the Western Allies played a significant role in shaping the post-war world. They established organizations like the United Nations to promote peace and cooperation. The Western Allies also helped rebuild war-torn Europe through initiatives such as the Marshall Plan, which aimed to restore economic stability and prevent the spread of communism.
