1. Japanese attack on Pearl Harbor.
2. Germany and Italy declare war on USA 4 days later.
3. Extensive assistance given to the British by the US before the US formally entered World War Two. These aid programs and activities, like Lend Lease, supplied the British with desperately needed supplies, including oil, warships, weapons, food, and countless other items without which Great Britain might have been defeated by Germany before the US was able to overcome domestic resistance to getting involved in a European conflict. These aid programs were a violation of neutrality which the Germans ignored, not wanting the US to enter the war through subterfuge and misdirection, as it had in WW1. When Japan attacked Pearl Harbor, Germany was compelled by treaty obligations to declare war on the US, which in any case had been covertly engaging in limited hostilities against Germany for the previous two years.

American involvement in World War I significantly shifted the balance of power in favor of the Allies. With fresh troops and substantial resources, the U.S. helped to replenish weary forces and bolster morale among Allied nations. The entry of American forces in 1917 accelerated the war's conclusion, leading to the eventual defeat of the Central Powers. Furthermore, the U.S. played a crucial role in shaping the post-war peace process, including the Treaty of Versailles.
