Arms controlArms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Historically, arms control may apply to melee weapons (such as swords) before the invention of firearm. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country.
Nuclear peaceNuclear peace is a theory of international relations which argues that the presence of nuclear weapons may in some circumstances decrease the risk of crisis escalation, since parties will seek to avoid situations that could lead to the use of nuclear weapons. Proponents of nuclear peace theory therefore believe that controlled nuclear proliferation may be beneficial for global stability. Critics argue that nuclear proliferation increases the chance of nuclear war through either deliberate or in-deliberate use of nuclear weapons, as well as the likelihood of nuclear material falling into the hands of violent non-state actors.
Nuclear-free zoneA nuclear-free zone is an area in which nuclear weapons (see nuclear-weapon-free zone) and nuclear power plants are banned. The specific ramifications of these depend on the locale in question. Nuclear-free zones usually neither address nor prohibit radiopharmaceuticals used in nuclear medicine even though many of them are produced in nuclear reactors. They typically do not prohibit other nuclear technologies such as cyclotrons used in particle physics. Several sub-national authorities worldwide have declared themselves "nuclear-free".
Peace symbolsA number of peace symbols have been used many ways in various cultures and contexts. The dove and olive branch was used symbolically by early Christians and then eventually became a secular peace symbol, popularized by a Dove lithograph by Pablo Picasso after World War II. In the 1950s the "peace sign", as it is known today (also known as "peace and love"), was designed by Gerald Holtom as the logo for the British Campaign for Nuclear Disarmament (CND), a group at the forefront of the peace movement in the UK, and adopted by anti-war and counterculture activists in the US and elsewhere.
Arms raceAn arms race occurs when two or more groups compete in military superiority. It consists of a competition between two or more states to have superior armed forces, concerning production of weapons, the growth of a military, and the aim of superior military technology. Unlike a sporting race, which constitutes a specific event with winning interpretable as the outcome of a singular project, arms races constitute spiralling systems of on-going and potentially open-ended behavior.
Debate over the atomic bombings of Hiroshima and NagasakiSubstantial 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). On 26 July 1945, United States President Harry S. Truman, British Prime Minister Winston Churchill and President of China Chiang Kai-shek issued the Potsdam Declaration, which outlined the terms of surrender for the Empire of Japan as agreed upon at the Potsdam Conference.
Aldermaston MarchesThe Aldermaston marches were anti-nuclear weapons demonstrations in the 1950s and 1960s, taking place on Easter weekend between the Atomic Weapons Research Establishment at Aldermaston in Berkshire, England, and London, over a distance of fifty-two miles, or roughly 83 km. At their height in the early 1960s they attracted tens of thousands of people and were the highlight of the Campaign for Nuclear Disarmament (CND) calendar. Similar demonstrations also took place around the world.
Stability–instability paradoxThe stability–instability paradox is an international relations theory regarding the effect of nuclear weapons and mutually assured destruction. It states that when two countries each have nuclear weapons, the probability of a direct war between them greatly decreases, but the probability of minor or indirect conflicts between them increases. This occurs because rational actors want to avoid nuclear wars, and thus they neither start major conflicts nor allow minor conflicts to escalate into major conflicts—thus making it safe to engage in minor conflicts.
Bulletin of the Atomic ScientistsThe Bulletin of the Atomic Scientists is a nonprofit organization concerning science and global security issues resulting from accelerating technological advances that have negative consequences for humanity. The Bulletin publishes content at both a free-access website and a bi-monthly, nontechnical academic journal. The organization has been publishing continuously since 1945, when it was founded by Albert Einstein and former Manhattan Project scientists as the Bulletin of the Atomic Scientists of Chicago immediately following the atomic bombings of Hiroshima and Nagasaki.
Bikini AtollBikini Atoll (ˈbɪkᵻˌniː or bᵻˈkiːni; Marshallese: Pikinni, pikinniy, meaning "coconut place"), known as Eschscholtz Atoll between the 1800s and 1946, is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. The Atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. After the Second World War, the atoll was chosen by the United States as a nuclear weapon testing site.
