The United States, who had, since December 1941, primarily focused on the conflict with the Japanese Empire, eventually established an Atlantic front in order to support their European allies, beginning in November 1942 with an amphibious landing in North Africa, later to continue the campaign in Sicily and on the Italian peninsula and invade France on the beaches of Normandy in 1944. Their colossal military strength and favorable strategic position in between two oceans without territorial borders to any of the Axis powers allowed the US forces to safely wage an offensive two-front war by maintaining the initiative in the Pacific War, contain and defeat Japan and also increase American presence in Europe that ensures Allied victory over Nazi Germany.
