Pearl Harbor Day
When:On the morning of December 7, 1941, Japan launched a sneak attack on the U.S. Pacific Fleet’s base at Pearl Harbor in Hawaii, as part of a plan to eliminate any potential challenge to Japanese conquests in Asia. The attack compelled the United States to enter World War II as a combatant, and to wage a costly, bloody struggle to defeat the Japanese empire.
The events set in motion by the attack also led to the United States becoming a global superpower.
