During World War II, which countries comprised the Allies?

The countries that comprised the Allies during World War II were primarily Great Britain, the United States, and the Soviet Union. These nations formed a coalition in response to the Axis Powers, which included Germany, Italy, and Japan.

Great Britain played a crucial role in the early years of the war, particularly in Europe, while the United States provided significant military, economic, and logistical support, especially following its entry into the war after the attack on Pearl Harbor in December 1941. The Soviet Union was pivotal on the Eastern Front, enduring massive initial losses before turning the tide against the Nazis.

Together, these three nations coordinated their efforts in various military campaigns across Europe, Asia, and the Pacific, ultimately leading to the defeat of the Axis Powers. This coalition was characterized by a spirit of collaboration despite significant ideological differences, which played a vital role in their shared victory.

The other options provided do not reflect the major Allied powers that fought against the Axis in World War II: Germany, Italy, and Japan were the main Axis nations, while France, China, and Canada were also parts of the Allied struggle but not the core leaders of the movement. Similarly, Spain, Portugal, and Switzerland remained neutral during the conflict.
