full_context: Document 1: Naval Station Pearl Harbor: Naval Station Pearl Harbor is a U.S. naval base adjacent to Honolulu, in the U.S. state of Hawaii. In 2010, along with the United States Air Force's Hickam Air Force Base, the facility was merged to form Joint Base Pearl Harbor–Hickam.
Document 2: Hawaii: The Kingdom of Hawai ʻi was sovereign from 1810 until 1893 when the monarchy was overthrown by resident American and European capitalists and landholders.

Document 3: Pacific War: Nishimura's force consisted of two battleships, one cruiser and four destroyers. Because they were observing radio silence, Nishimura was unable to synchronize with Shima and Kurita. Nishimura and Shima had failed to even coordinate their plans before the attacks – they were long-time rivals and neither wished to have anything to do with the other. When he entered the narrow Surigao Strait at about 02:00, Shima was 22 miles (40 km) behind him, and Kurita was still in the Sibuyan Sea, several hours from the beaches at Leyte. As they passed Panaon Island, Nishimura's force ran into a trap set for them by the U.S.-Australian 7th Fleet Support Force. R. Adm. Jesse Oldendorf had six battleships, four heavy cruisers, four light cruisers, 29 destroyers and 39 PT boats. To pass the strait and reach the landings, Nishimura had to run the gauntlet. At about 03:00 the Japanese battleship Fusō and three destroyers were hit by torpedoes and Fusō broke in two. At 03:50 the U.S. battleships opened fire. Radar fire control meant they could hit targets from a much greater distance than the Japanese. The battleship Yamashiro, a cruiser and a destroyer were crippled by 16-inch (406 mm) shells; Yamashiro sank at 04:19. Only one of Nishimura's force of seven ships survived the engagement. At 04:25 Shima's force of two cruisers and eight destroyers reached the battle. Seeing Fusō and believing her to be the wrecks of two battleships, Shima ordered a retreat, ending the last battleship-vs-battleship action in history.
Document 4: Pacific War: President Franklin Roosevelt ordered General Douglas MacArthur in the Philippines to formulate a Pacific defence plan with Australia in March 1942. Curtin agreed to place Australian forces under the command of MacArthur who became Supreme Commander, South West Pacific.

Document 5: Wake Island: With the annexation of Hawaii in 1898 and the seizure of Guam and the Philippines during the Spanish -- American War that same year, the United States began to consider unclaimed and uninhabited Wake Island, located approximately halfway between Honolulu and Manila, as a good location for a telegraph cable station and coaling station for refueling warships of the rapidly expanding United States Navy and passing merchant and passenger steamships. On July 4, 1898, United States Army Brigadier General Francis V. Greene of the 2nd Brigade, Philippine Expeditionary Force, of the Eighth Army Corps, stopped at Wake Island and raised the American flag while en route to the Philippines on the steamship liner SS China.

Long term basing at Pearl Harbor was so strongly opposed by the commander, Admiral James O. Richardson, that he personally protested in Washington. Political considerations were thought sufficiently important that he was relieved by Admiral Husband E. Kimmel, who was in command at the time of the attack on Pearl Harbor.
