The nuclear weapons debate refers to the controversies surrounding the threat, use and stockpiling of nuclear weapons.
 Even before the first nuclear weapons had been developed, scientists involved with the Manhattan Project were divided over the use of the weapon.
 The only time nuclear weapons have been used in warfare was during the final stages of World War II when United States Army Air Forces B-29 Superfortress bombers dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in early August 1945.
 The role of the bombings in Japan's surrender and the U.S.'s ethical justification for them have been the subject of scholarly and popular debate for decades.
During the final stage of World War II, the United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively.
 The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement.
 The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.
Hiroshima Castle (広島城 , Hiroshima-jō ) , sometimes called Carp Castle (鯉城 , Rijō ) , was a castle in Hiroshima, Japan that was the home of the "daimyō" (feudal lord) of the Hiroshima han (fief).
 The castle was constructed in the 1590s, but was destroyed by the atomic bombing on August 6, 1945.
 It was rebuilt in 1958, a replica of the original that now serves as a museum of Hiroshima's history before World War II.
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.
 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.
 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.
 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.
 Following the end of the occupation, the countries' relationship prospered again.
 A new military alliance treaty, an exchange of technology and culture produced a strong alliance.
 The countries' trade relationship has particularly prospered since then, with Japanese automobiles and consumer electronics being especially popular.
The United States is known to have possessed three types of weapons of mass destruction: nuclear weapons, chemical weapons, and biological weapons.
 The U.S. is the only country to have used nuclear weapons in combat, when it detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki during World War II.
 It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project".
 The United States pioneered the development of both the nuclear fission and hydrogen bombs (the latter involving nuclear fusion).
 It was the world's first and only nuclear power for four years (1945–1949), until the Soviet Union managed to produce its own nuclear weapon.
 The United States has the second largest number of deployed nuclear weapons in the world, after Russia.
Hiroshima Peace Memorial Park (広島平和記念公園 , Hiroshima Heiwa Kinen Kōen ) is a memorial park in the center of Hiroshima, Japan.
 It is dedicated to the legacy of Hiroshima as the first city in the world to suffer a nuclear attack, and to the memories of the bomb's direct and indirect victims (of whom there may have been as many as 140,000).
 The Hiroshima Peace Memorial Park was planned and designed by the Japanese Architect Kenzō Tange at Tange Lab.
