Question: Pearlridge overlooks an historic lagoon, the attack on which, caused the United States to enter into which war?

<P0-S0> The Indo-Pakistani War of 1965 was a culmination of skirmishes that took place between April 1965 and September 1965 between Pakistan and India. <P0-S1>  The conflict began following Pakistan's Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against Indian rule. <P0-S2>  India retaliated by launching a full-scale military attack on West Pakistan. <P0-S3>  The seventeen-day war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II. <P0-S4>  Hostilities between the two countries ended after a United Nations mandated ceasefire was declared following diplomatic intervention by the Soviet Union and the United States, and the subsequent issuance of the Tashkent Declaration. <P0-S5>  Much of the war was fought by the countries' land forces in Kashmir and along the border between India and Pakistan. <P0-S6>  This war saw the largest amassing of troops in Kashmir since the Partition of British India in 1947, a number that was overshadowed only during the 2001–2002 military standoff between India and Pakistan. <P0-S7>  Most of the battles were fought by opposing infantry and armoured units, with substantial backing from air forces, and naval operations. <P0-S8>  The war exposed Pakistan's inadequate standards of military training, its misguided selection of officers, poor command and control arrangements, poor intelligence gathering and bad intelligence procedures. <P0-S9>  In spite of these shortcomings, the Pakistan Army managed to fight the larger Indian Army. <P0-S10>  Many details of this war, like those of other Indo-Pakistani Wars, remain unclear. <SEP> <P1-S0> Japan–United States relations (日米関係 ) began in the late 18th and early 19th century, with the diplomatic but force-backed missions of U.S. ship captains James Glynn and Matthew C. Perry to the Tokugawa shogunate being of particular importance. <P1-S1>  The countries maintained relatively cordial relations after that, and Japanese immigration to the United States was prominent until the 20th century, up until the 1930s, when Japanese actions during the Second Sino-Japanese War caused the United States to impose harsh sanctions against Japan, ultimately leading to the Japanese surprise attack against the US naval base at Pearl Harbor, opening the Pacific War theater of World War II. <P1-S2>  The United States and its Allies ultimately defeated Japan, and war ended with the American atomic bombings of the Japanese cities of Hiroshima and Nagasaki. <P1-S3>  Japan surrendered, and was subjected to seven years of military occupation by the United States, during which the American occupiers helped rebuild the country, shared American technology, and carried out widespread political and economic reforms so as to transform Japan into a democracy and a potential bulwark against Communism. <P1-S4>  Following the end of the occupation, the countries' relationship prospered again. <P1-S5>  A new military alliance treaty, an exchange of technology and culture produced a strong alliance. <P1-S6>  The countries' trade relationship has particularly prospered since then, with Japanese automobiles and consumer electronics being especially popular. <SEP> <P2-S0> Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. <P2-S1>  Much of the harbor and surrounding lands is a United States Navy deep-water naval base. <P2-S2>  It is also the headquarters of the United States Pacific Fleet. <P2-S3>  The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. <P2-S4>  The attack on Pearl Harbor by the Empire of Japan on December 7, 1941, was the immediate cause of the United States' entry into World War II. <SEP> <P3-S0>  Opened in 1972 and expanded in 1976, the enclosed mall is split up into three "phases" (Uptown, Downtown, & Phase Three) and overlooks historic Pearl Harbor and the USS Arizona Memorial. <P3-S1> Pearlridge (formerly Pearlridge Center) is the second largest shopping center in Hawaiʻ i, after Ala Moana, and is Hawaiʻ i's largest enclosed shopping center, located in ʻ Aiea. <P3-S2>  The property includes the only monorail in Hawaiʻ i, the only emergency clinic located on mall property (Pali Momi Medical Center), and an eight story office complex (Pearlridge Office Center).
