The United States entered both World War I and World War II a few years after each war began. Our entrance into each war was a major factor in determining the outcome of both wars.

In World War I, both sides were fighting each other in a long war of attrition. Even though Germany believed it was close to winning the war, they weren’t as close to winning as they thought they were. When we joined World War I, we brought fresh troops to the Allies. We also provided needed supplies. In World War I, the entrance of the United States into the war on the side of the Allies was the deciding factor in the result of the war. Our entrance into World War I enabled the Allies to win this war.

In World War II, we had no choice in joining the war. After we were attacked at Pearl Harbor, we had to join the war. Our entrance into World War II was also a significant factor. We could now openly help Great Britain fight against Germany and Italy. After many Axis victories in Europe, Great Britain was the only major country remaining in the fight against Germany and Italy. With the United States entering the war and providing troops, weapons, and supplies, we were able to help Great Britain stop the Axis advance in North Africa and Europe. We also were able to stop the Japanese advance in the Pacific Ocean and in Asia after we recovered from the attack at Pearl Harbor. Our war industries helped to rebuild our military in the Pacific region very quickly. As a result, our military was able to stop the Japanese advance, and then it began to pursue the Japanese as they retreated.

The entrance of the United States into both World War I and World War II was a huge factor in helping the Allies win both of these wars.
