Did Japan Attack Pearl Harbor for Oil? | History

Summary

The 1941 Pearl Harbor attack by Japan marked a devastating shift in US-Japan relations. Despite being allies in World War I, Japan's aggressive expansionism and resource needs, exacerbated by the Great Depression, led to escalating tensions with the US. Economic sanctions, including an oil embargo, provoked Japan, leading to their surprise attack on December 7, 1941. The strike crippled the US fleet, but failed to deliver a decisive blow, ultimately leading to Japan’s defeat after key losses like the Battle of Midway. The incident drastically shifted the balance of power in the Pacific during World War II.
