The USA

The United States was one of the major players in World War 2, significantly contributing to the success of the Allies. While its agricultural sector could feed the military populace, its manufacturing sector could generate large quantities of weapons and other supplies. Following the Japanese attack on Pearl Harbor on December 7, 1941, the nation entered the war. About 16 million Americans served in the military throughout the conflict. They engaged in combat with Nazi Germany, Italy, and Japan in both Europe and Asia. The US made a significant contribution to the war effort by supplying weapons and other supplies.

More than two-thirds of all Allied aircraft throughout the war were built at the nation's factories. They possessed 1,200 navy vessels, including more than 100 carriers, and around 320,000 aircraft. The world's most devastating force was once a very weak power that became stronger through time. Whether it was using high explosives to destroy Panzer Lehr, destroying Tokyo with fire, or destroying vital German industrial infrastructure, it was a powerful force. Japan was defeated thanks only to the efforts of the United States.

The two main Axis Powers were outwitted by them in every aspect of the war that had led to so many of their early wins over Germany and Japan (armored mobile warfare, close air support, air supremacy, naval aviation, submarine warfare, and amphibious warfare). The Allies' victory was largely attributed to advancements in radar, anti-submarine technology, and anti-aircraft gunnery, particularly the proximity fuse. The US was able to produce tanks, aircraft, and other military weaponry at a record-breaking rate because of industrial mass manufacturing techniques. Japan, on the other hand, eventually submitted unconditionally as a result of its nuclear arsenal.
