Mushroom cloud from the 1954 explosion of Castle Bravo, the largest nuclear weapon detonated by the U.S.. A nuclear holocaust, also known as a nuclear apocalypse, nuclear annihilation, nuclear armageddon, or atomic holocaust, is a theoretical scenario where the mass detonation of nuclear weapons causes widespread destruction and radioactive fallout, with global consequences.
[7] [8] [9] A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including human extinction. [10] To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki.
The thermonuclear Tsar Bomba was the most powerful bomb ever detonated. [6] As thermonuclear weapons represent the most efficient design for weapon energy yield in weapons with yields above 50 kilotons of TNT (210 TJ), virtually all the nuclear weapons of this size deployed by the five nuclear-weapon states under the Non-Proliferation Treaty ...
One major change between Civilization V and Civilization VI is that both leaders and civilizations have a benefit. The Aztecs, led by Montezuma I, was a pre-order DLC until becoming free to all players on January 19, 2017. City improvements such as military installations are now built in separate tiles from the main city tile in Civilization VI.
Mutual assured destruction (MAD) is a doctrine of military strategy and national security policy which posits that a full-scale use of nuclear weapons by an attacker on a nuclear-armed defender with second-strike capabilities would result in the complete annihilation of both the attacker and the defender.

Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare. On July 20, 1956, at Bikini Atoll, the 5-megaton-yield thermonuclear weapon Redwing Tewa was detonated. [1]
Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction).
With the advent of nuclear technology and its increasingly global fallout an anti-nuclear movement formed and in 1963, three (UK, US, Soviet Union) of the then four nuclear states and many non-nuclear states signed the Limited Test Ban Treaty, pledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space.
