“Pearl Harbor, known to Hawaiians as Puʻuloa, is a lagoon harbor on the island of Oʻahu, Hawaiʻi, west of Honolulu. Much of the harbor and surrounding lands is a United States Navy deep-water naval base. It is also the headquarters of the U.S. Pacific Fleet. The attack on Pearl Harbor by the Empire of Japan on December 7, 1941, brought the United States into World War II”. – Wikipedia
