An underlying cause of the war between the US and Japan from 1941 to 1945 was Japan's expansionist ambitions in Asia and the Pacific, driven by a desire for Natural Resources and territorial control. The US opposed Japanese aggression, particularly in China and Southeast Asia, and responded with economic sanctions and trade embargoes, notably cutting off oil exports to Japan. This escalating tension culminated in Japan's surprise attack on Pearl Harbor in December 1941, which prompted the US to enter the war.
