The United States, with the consent of the United Kingdom as laid down in the Quebec Agreement, dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki in August 1945, during the final stage of World War II.<br/><br/> The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.
On Monday, August 6, 1945, at 8:15 am, the nuclear bomb 'Little Boy' was dropped on Hiroshima by an American B-29 bomber, the Enola Gay, directly killing an estimated 80,000 people.<br/><br/> By the end of the year, injury and radiation brought the total number of deaths to 90,000–166,000. The population before the bombing was around 340,000 to 350,000. Approximately 70% of the city's buildings were destroyed, and another 7% severely damaged.
'Fat Man' was the codename for the type of atomic bomb that was detonated over the Japanese city of Nagasaki by the United States on 9 August 1945. It was the second of the only two nuclear weapons ever used in warfare, the first being 'Little Boy', and its detonation marked the third ever man-made nuclear explosion in history.<br/><br/> It was built by scientists and engineers at Los Alamos Laboratory using plutonium from the Hanford Site and dropped from the Boeing B-29 Superfortress Bockscar.
China established the Lop Nur Nuclear Test Base on 16 October 1959 with Soviet assistance in selection of the site, with its headquarters at Malan, about 125 km (78 mi) northwest of Qinggir.<br/><br/> The first Chinese nuclear bomb test, codenamed '596', was tested at Lop Nur in 1964. The PRC detonated its first hydrogen bomb on June 17, 1967. Until 1996, 45 nuclear tests were conducted.
The Great Proletarian Cultural Revolution, commonly known as the Cultural Revolution, was a socio-political movement that took place in the People's Republic of China from 1966 through 1976. Set into motion by Mao Zedong, then Chairman of the Communist Party of China, its stated goal was to enforce socialism in the country by removing capitalist, traditional and cultural elements from Chinese society, and impose Maoist orthodoxy within the Party. <br/><br/> The Cultural Revolution damaged the country on a great scale economically and socially. Millions of people were persecuted in the violent factional struggles that ensued across the country, and suffered a wide range of abuses including torture, rape, imprisonment, sustained harassment, and seizure of property. A large segment of the population was forcibly displaced, most notably the transfer of urban youth to rural regions during the Down to the Countryside Movement. Historical relics and artifacts were destroyed. Cultural and religious sites were ransacked.
The Enola Gay is a Boeing B-29 Superfortress bomber named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945;, during the final stages of World War II, it became the first aircraft to drop an atomic bomb.<br/><br/> The bomb, code-named 'Little Boy', was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction. Enola Gay participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki being bombed instead.

Teller immigrated to the United States in the 1930s, and was an early member of the Manhattan Project charged with developing the first atomic bombs. During this time he made a serious push to develop the first fusion-based weapons as well, but these were deferred until after World War II.<br/><br/> After his controversial testimony in the security clearance hearing of his former Los Alamos colleague J. Robert Oppenheimer, Teller was ostracized by much of the scientific community. He continued to find support from the U.S. government and military research establishment, particularly for his advocacy for nuclear energy development, a strong nuclear arsenal, and a vigorous nuclear testing program.<br/><br/> He was a co-founder of Lawrence Livermore National Laboratory (LLNL), and was both its director and associate director for many years.

Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity in July 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945.<br/><br/> The purpose of the tests was to investigate the effect of nuclear weapons on warships.

'Little Boy' was the codename for the atomic bomb dropped on the Japanese city of Hiroshima on 6 August 1945.<br/><br/> It was the first atomic bomb to be used in warfare. The Hiroshima bombing was the second artificial nuclear explosion in history, after the Trinity test, and the first uranium-based detonation. It exploded with an energy of approximately 15 kilotons of TNT. The bomb caused significant destruction to the city of Hiroshima.
Julius Robert Oppenheimer(April 22, 1904 – February 18, 1967) was an American theoretical physicist and professor of physics at the University of California, Berkeley. He is among the persons who are often called the 'father of the atomic bomb' for their role in the Manhattan Project, the World War II project that developed the first nuclear weapons. The first atomic bomb was detonated on July 16, 1945, in the Trinity test in New Mexico; Oppenheimer remarked later that it brought to mind words from the Bhagavad Gita: 'Now I am become Death, the destroyer of worlds'.<br/><br/> After the war he became a chief advisor to the newly created United States Atomic Energy Commission and used that position to lobby for international control of nuclear power to avert nuclear proliferation and an arms race with the Soviet Union. After provoking the ire of many politicians with his outspoken opinions during the Second Red Scare, he had his security clearance revoked in a much-publicized hearing in 1954, and was effectively stripped of his direct political influence; he continued to lecture, write and work in physics. Nine years later President John F. Kennedy awarded (and Lyndon B. Johnson presented) him with the Enrico Fermi Award as a gesture of political rehabilitation.
