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.
In nuclear strategy, a first strike or preemptive strike is a preemptive surprise attack employing overwhelming force. First strike capability is a country's ability to defeat another nuclear power by destroying its arsenal to the point where the attacking country can survive the weakened retaliation while the opposing side is left unable to continue war. The preferred methodology is to attack the opponent's strategic nuclear weapon facilities, command and control sites, and storage depots first. The strategy is called counterforce.
In nuclear strategy, minimal deterrence, also known as minimum deterrence and finite deterrence, is an application of deterrence theory in which a state possesses no more nuclear weapons than is necessary to deter an adversary from attacking. Pure minimal deterrence is a doctrine of no first use, holding that the only mission of nuclear weapons is to deter a nuclear adversary by making the cost of a first strike unacceptably high. To present a credible deterrent, there must be the assurance that any attack would trigger a retaliatory strike. In other words, minimal deterrence requires rejecting a counterforce strategy in favor of pursuing survivable force that can be used in a countervalue second strike.
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 cause the complete annihilation of both the attacker and the defender. It is based on the theory of rational deterrence, which holds that the threat of using strong weapons against the enemy prevents the enemy's use of those same weapons. The strategy is a form of Nash equilibrium in which, once armed, neither side has any incentive to initiate a conflict or to disarm.
In nuclear ethics and deterrence theory, no first use (NFU) refers to a type of pledge or policy wherein a nuclear power formally refrains from the use of nuclear weapons or other weapons of mass destruction (WMD) in warfare, except for as a second strike in retaliation to an attack by an enemy power using WMD. Such a pledge would allow for a unique state of affairs in which a given nuclear power can be engaged in a conflict of conventional weaponry while it formally forswears any of the strategic advantages of nuclear weapons, provided the enemy power does not possess or utilize any such weapons of their own. The concept is primarily invoked in reference to nuclear mutually assured destruction but has also been applied to chemical and biological warfare, as is the case of the official WMD policy of India.
Nuclear utilization target selection (NUTS) is a hypothesis regarding the use of nuclear weapons often contrasted with mutually assured destruction (MAD). NUTS theory at its most basic level asserts that it is possible for a limited nuclear exchange to occur and that nuclear weapons are simply one more rung on the ladder of escalation pioneered by Herman Kahn. This leads to a number of other conclusions regarding the potential uses of and responses to nuclear weapons.
Deterrence theory refers to the scholarship and practice of how threats or limited force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties. The central problem of deterrence revolves around how to credibly threaten military action or nuclear punishment on the adversary despite its costs to the deterrer.
AirLand Battle was the overall conceptual framework that formed the basis of the US Army's European warfighting doctrine from 1982 into the late 1990s. AirLand Battle emphasized close coordination between land forces acting as an aggressively maneuvering defense, and air forces attacking rear-echelon forces feeding those front line enemy forces. AirLand Battle replaced 1976's "Active Defense" doctrine, and was itself replaced by "Full Spectrum Operations" in 2001.
The Single Integrated Operational Plan (SIOP) was the United States' general plan for nuclear war from 1961 to 2003. The SIOP gave the President of the United States a range of targeting options, and described launch procedures and target sets against which nuclear weapons would be launched. The plan integrated the capabilities of the nuclear triad of strategic bombers, land-based intercontinental ballistic missiles (ICBM), and sea-based submarine-launched ballistic missiles (SLBM). The SIOP was a highly classified document, and was one of the most secret and sensitive issues in U.S. national security policy.
Massive retaliation, also known as a massive response or massive deterrence, is a military doctrine and nuclear strategy in which a state commits itself to retaliate in much greater force in the event of an attack.
Flexible response was a defense strategy implemented by John F. Kennedy in 1961 to address the Kennedy administration's skepticism of Dwight Eisenhower's New Look and its policy of massive retaliation. Flexible response calls for mutual deterrence at strategic, tactical, and conventional levels, giving the United States the capability to respond to aggression across the spectrum of war, not limited only to nuclear arms.
Bernard Brodie was an American military strategist well known for establishing the basics of nuclear strategy. Known as "the American Clausewitz," and "the original nuclear strategist," he was an initial architect of nuclear deterrence strategy and tried to ascertain the role and value of nuclear weapons after their creation.
The New Look was the name given to the national security policy of the United States during the administration of President Dwight D. Eisenhower. It reflected Eisenhower's concern for balancing the Cold War military commitments of the United States with the nation's financial resources. The policy emphasised reliance on strategic nuclear weapons as well as a reorganisation of conventional forces in an effort to deter potential threats, both conventional and nuclear, from the Eastern Bloc of nations headed by the Soviet Union.
In military doctrine, countervalue is the targeting of an opponent's assets that are of value but not actually a military threat, such as cities and civilian populations. Counterforce is the targeting of an opponent's military forces and facilities. The Oxford English Dictionary, 2nd ed., records the first use of the word in 1660 and the first use in the modern sense in 1965 in which it is described as a "euphemism for attacking cities".
A strategic nuclear weapon (SNW) refers to a nuclear weapon that is designed to be used on targets often in settled territory far from the battlefield as part of a strategic plan, such as military bases, military command centers, arms industries, transportation, economic, and energy infrastructure, and heavily populated areas such as cities and towns, which often contain such targets. It is in contrast to a tactical nuclear weapon, which is designed for use in battle as part of an attack with and often near friendly conventional forces, possibly on contested friendly territory.
The following outline is provided as an overview of and topical guide to nuclear technology:
The "nuclear umbrella" is a guarantee by a nuclear weapons state to defend a non-nuclear allied state. The context is usually the security alliances of the United States with Australia, Japan, South Korea, and the North Atlantic Treaty Organization. Those alliances were formed because of the Cold War and the Soviet Union. For some countries, it was an alternative to acquiring nuclear weapons themselves; other alternatives include regional nuclear-weapon-free zones or nuclear sharing.
The military doctrine of Russia is a strategic planning document of Russia and represents a system of officially state adopted views of preparation for the armed protection of Russia. The most recent revision of the military doctrine was approved in 2014.
Nuclear escalation is the concept of a large conflict escalating from conventional warfare to nuclear warfare.
The Italian nuclear weapons program was an effort by Italy to develop nuclear weapons in the late 1960s and early 1970s. Italian scientists such as Enrico Fermi and Edoardo Amaldi had been at the forefront of the development of the technology behind nuclear weapons, but the country was banned from developing the technology at the end of the Second World War. After abortive proposals to establish a multilateral program with NATO Allies in the 1950s and 1960s, Italy launched a national nuclear weapons program. The country converted the light cruiser Giuseppe Garibaldi and developed and tested a ballistic missile called Alfa. The program ended in 1975 upon Italy's accession to the Non-Proliferation Treaty. Currently, Italy does not produce or possess nuclear weapons but takes part in the NATO nuclear sharing program, hosting B61 nuclear bombs at the Aviano and Ghedi Air Bases.
