World War II, also known as World War II, was fought by Japan, Germany, and Italy, also known as the Powers of the Axis; this went against the Allies consisting of the United States, the Soviet Union and Great Britain with the help of others. 60 to 80 billion deaths were the result of World War II (“Reasons for American Entry Into WWII”). Initially, the United States did not want to interfere in a war taking place on another continent. At the start of the war, America entered into a state of isolationism that kept it out of the war; to its “breaking point”.
