Nuclear warfare, also known as atomic warfare, is a military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result. A major nuclear exchange would likely have long-term effects, primarily from the fallout released, and could also lead to secondary effects, such as "nuclear winter", nuclear famine, and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including the extinction of the human species.
Building on major scientific breakthroughs made during the 1930s, the United Kingdom began the world's first nuclear weapons research project, codenamed Tube Alloys, in 1941, during World War II. The United States, in collaboration with the United Kingdom, initiated the Manhattan Project the following year to build a weapon using nuclear fission. The project also involved Canada. In August 1945, the atomic bombings of Hiroshima and Nagasaki were conducted by the United States, with British consent, against Japan at the close of that war, standing to date as the only use of nuclear weapons in hostilities.
Lewis Lichtenstein Strauss was an American government official, businessman, philanthropist and naval officer. He was one of the original members of the United States Atomic Energy Commission (AEC) in 1946 and he served as the commission's chair in the 1950s. Strauss was a major figure in the development of nuclear weapons after World War II, nuclear energy policy and nuclear power in the United States.
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 USAAF 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.
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.
Hiroshima is a 1995 Japanese-Canadian war drama film directed by Koreyoshi Kurahara and Roger Spottiswoode about the decision-making processes that led to the dropping of the atomic bombs by the United States on the Japanese cities of Hiroshima and Nagasaki toward the end of World War II. The three-hour film was made for television and had no theatrical release.
Martin Jay Sherwin was an American historian. His scholarship mostly concerned the history of nuclear weapons and nuclear proliferation. He served on the faculty at Princeton University, the University of Pennsylvania, the University of California, Berkeley, and as the Walter S. Dickson Professor of English and American History at Tufts University, where he founded the Nuclear Age History and Humanities Center.
Substantial debate exists over the ethical, legal, and military aspects of the atomic bombings of Hiroshima and Nagasaki on 6 August and 9 August 1945 at the close of World War II (1939–45).
Herbert Feis was an American historian, author, and economist who was the Advisor on International Economic Affairs in the US Department of State during the Herbert Hoover and Franklin Roosevelt administrations.
American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer is a 2005 biography of theoretical physicist J. Robert Oppenheimer, the leader of the Manhattan Project which produced the first nuclear weapons, written by Kai Bird and Martin J. Sherwin over a period of 25 years. It won numerous awards, including the 2006 Pulitzer Prize for Biography or Autobiography.
This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons. The availability of intelligence on recent advancements in nuclear weapons of several major countries is limited because of the classification of technical knowledge of nuclear weapons development.
Rose Eilene Gottemoeller is an American diplomat who served as Deputy Secretary General of NATO from October 2016 to October 2019 under Secretary General Jens Stoltenberg. Before then she was the Under Secretary of State for Arms Control and International Security at the U.S. State Department.

He is a graduate of Harvard College, Columbia University and Tufts University. Hershberg is a leading scholar on Cold War history and a former Director of the Cold War International History Project at the Woodrow Wilson Center in Washington, DC. His first book was on the life of former Harvard President James Bryant Conant.
The Manhattan Projects is a science fiction comic book series co-created by writer Jonathan Hickman and artist Nick Pitarra published by Image Comics. The premise is an alternate history near the end of World War II in which the Manhattan Project was a front for other more esoteric science fiction ideas. The series is a monthly ongoing and began in March 2012 to much critical acclaim.
Brian Knappenberger is an American documentary filmmaker, known for The Internet's Own Boy: The Story of Aaron Swartz, We Are Legion: The Story of the Hacktivists, and Turning Point: 9/11 and the War on Terror and his work on Bloomberg Game Changers.
The Bomb is a 2015 American documentary film about the history of nuclear weapons, from theoretical scientific considerations at the very beginning, to their first use on August 6, 1945, to their global political implications in the present day. The film was written and directed by Rushmore DeNooyer for PBS. The project took a year and a half to complete, since much of the film footage and images were only recently declassified by the United States Department of Defense.
Oppenheimer is a 2023 epic biographical thriller film written, directed, and produced by Christopher Nolan. It follows the life of J. Robert Oppenheimer, the American theoretical physicist who helped develop the first nuclear weapons during World War II. Based on the 2005 biography American Prometheus by Kai Bird and Martin J. Sherwin, the film chronicles Oppenheimer's studies, his direction of the Los Alamos Laboratory, and his fall from grace after his 1954 security hearing. Cillian Murphy stars as Oppenheimer, alongside Robert Downey Jr. as the United States Atomic Energy Commission member Lewis Strauss. The ensemble supporting cast includes Emily Blunt, Matt Damon, Florence Pugh, Josh Hartnett, Casey Affleck, Rami Malek and Kenneth Branagh.
During the Russian invasion of Ukraine, several senior Russian politicians, including president Vladimir Putin, former president and prime minister Dmitry Medvedev, and foreign minister Sergey Lavrov, have made a number of statements widely seen as threatening the use of nuclear weapons. The possibility of Russia using tactical nuclear weapons, and the risk of broader nuclear escalation, has been widely discussed by commentators and in the media. Additionally, the Russian occupation of the Zaporizhzhia Nuclear Power Plant has led to a crisis over the safety of the plant and the risk of a nuclear disaster.
