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. [1] 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. [1] To present a credible deterrent, there must be the assurance that any attack would trigger a retaliatory strike. [2] 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.
While the United States and the Soviet Union each developed robust first- and second-strike capabilities during the Cold War, the People's Republic of China pursued a doctrine of minimal nuclear deterrence. Assuming that decision-makers make cost-benefit analyses when deciding to use force, China's doctrine calls for acquiring a nuclear arsenal only large enough to destroy an adversary's "strategic points" in such a way that the expected costs of a first strike outweigh the anticipated benefits. [3] India has also adopted this strategy, which they term Minimum Credible Deterrence. [4]
The "minimum credible deterrence" (also known as N-deterrence) policy of Pakistan is a defence and strategic principle on which the country's nuclear weapons program is based. This doctrine is not a part of the nuclear doctrine, which is designed for the use of the atomic weapons in a full-scale declared war if the conditions of the doctrine are surpassed. Instead, the policy of the Minimum Credible Deterrence falls under minimal deterrence as an inverse to the Mutually Assured Destruction (MAD), which is widely regarded as designed to dissuade India from taking any military actions against Pakistan, as it did during the Indo-Pakistani War of 1971.
Minimal deterrence represents one way of solving the security dilemma and avoiding an arms race. Decision-makers often feel pressured to expand their arsenals when they perceive them to be vulnerable to an adversary's first strike, especially when both sides seek to achieve the advantage. [5] Eliminating this perceived vulnerability reduces the incentive to produce more and advanced weapons. For example, the United States’ nuclear force exceeds the requirements of minimal deterrence, and is structured to strike numerous targets in multiple countries and to have the ability to conduct successful counterforce strikes with high confidence. [6] In response to this, China continues to modernize its nuclear forces because its leaders are concerned about the survivability of their arsenal in the face of the United States’ advances in strategic reconnaissance, precision strike, and missile defense. [7]
One disadvantage of minimal deterrence is that it requires an accurate understanding of the level of damage an adversary finds unacceptable, especially if that understanding changes over time so that a previously credible deterrent is no longer credible. [8] A minimal deterrence strategy must also account for the nuclear firepower that would be "lost" or "neutralized" during an adversary's counterforce strike. [9] Additionally, a minimal deterrence capability may embolden a state when it confronts a superior nuclear power, as has been observed in the relationship between China and the United States. [10] Finally, while pursuing minimal deterrence during arms negotiations allows states to make reductions without becoming vulnerable, further reductions may be undesirable once minimal deterrence is reached because they will increase a state's vulnerability and provide an incentive for an adversary to secretly expand its nuclear arsenal. [11]
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.
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. 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.
Nuclear strategy involves the development of doctrines and strategies for the production and use of nuclear weapons.
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 blackmail is a form of nuclear strategy in which one of states uses the threat of use of nuclear weapons to force an adversary to perform some action or make some concessions. It is a type of extortion that is related to brinkmanship.
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 of using 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. Deterrence in an international relations context is the application of deterrence theory to avoid conflict.
India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 172 nuclear weapons and has produced enough weapons-grade plutonium for up to 200 nuclear weapons. In 1999, India was estimated to have 800 kilograms (1,800 lb) of separated reactor-grade plutonium, with a total amount of 8,300 kilograms (18,300 lb) of civilian plutonium, enough for approximately 1,000 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II.
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. It is associated with the U.S. national security policy of the Eisenhower administration during the early stages of the Cold War.
The Nuclear Posture Review (NPR) is a process “to determine what the role of nuclear weapons in U.S. security strategy should be.” NPRs are the primary document for determining U.S. strategy for nuclear weapons and it outlines an overview of U.S. nuclear capabilities, changes to current stockpiles and capabilities, plans for deterrence, and plans for arms control policy with other nations.
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.
The Nuclear doctrine of Pakistan is a theoretical concept of military strategy that promotes deterrence by guaranteeing an immediate "massive retaliation" to an aggressive attack against the state.
Credible minimum deterrence is the principle on which India's nuclear strategy is based.
In nuclear strategy, 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".
The following outline is provided as an overview of and topical guide to nuclear technology:
The "Schlesinger Doctrine" is the name, given by the press, to a major re-alignment of United States nuclear strike policy that was announced in January 1974 by the US Secretary of Defense, James Schlesinger. It outlined a broad selection of counterforce options against a wide variety of potential enemy actions, a major change from earlier SIOP policies of the Kennedy and Johnson eras that focused on Mutually Assured Destruction and typically included only one or two "all-out" plans of action that used the entire U.S. nuclear arsenal in a single strike. A key element of the new plans were a variety of limited strikes solely against enemy military targets while ensuring the survivability of the U.S. second-strike capability, which was intended to leave an opening for a negotiated settlement.
Hans Møller Kristensen is director of the Nuclear Information Project at the Federation of American Scientists. He writes about nuclear weapons policy there; he is coauthor of the Nuclear Notebook column in the Bulletin of the Atomic Scientists, and the World Nuclear Forces appendix in Stockholm International Peace Research Institute's annual SIPRI Yearbook.
In nuclear strategy, a counterforce target is one that has a military value, such as a launch silo for intercontinental ballistic missiles, an airbase at which nuclear-armed bombers are stationed, a homeport for ballistic missile submarines, or a command and control installation.
The Full spectrum deterrence (previously known as Minimum Credible Deterrence is the defence and strategic principle on which the atomic weapons programme of Pakistan is based. This doctrine is not a part of the nuclear doctrine, which is designed for the use of the atomic weapons in a full-scale declared war if the conditions of the doctrine are surpassed. Instead, the policy of the Minimum Credible Deterrence falls under minimal deterrence as an inverse to the Mutually Assured Destruction, which is widely regarded as designed to dissuade India from taking any military actions against Pakistan, as it did in 1971. Pakistan has adopted No first use policy, like the other regional powers, India and China, have.
