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.
67-499: The result may be a nuclear peace , in which the presence of nuclear weapons decreases 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 inadvertent use of nuclear weapons, as well as
134-508: A US nuclear attack, Moscow might make rash moves (such as putting its forces on alert) that would provoke a US preemptive strike. An outline of current US nuclear strategy toward both Russia and other nations was published as the document " Essentials of Post–Cold War Deterrence " in 1995. In November 2020, the US successfully destroyed a dummy ICBM outside the atmosphere with another missile. Bloomberg Opinion writes that this defense ability "ends
201-471: A destructive agent so terrible that War shall mean annihilation and men's fears will force them to keep the peace." The concept was also described in 1863 by Jules Verne in his novel Paris in the Twentieth Century , though it was not published until 1994. The book is set in 1960 and describes "the engines of war", which have become so efficient that war is inconceivable and all countries are at
268-652: A follow-up article in the same publication, others criticized the analysis, including Peter Flory , the US Assistant Secretary of Defense for International Security Policy, who began by writing "The essay by Keir Lieber and Daryl Press contains so many errors, on a topic of such gravity, that a Department of Defense response is required to correct the record." Regarding reductions in Russian stockpiles, another response stated that "a similarly one-sided examination of [reductions in] U.S. forces would have painted
335-467: A full-scale Soviet retaliatory strike ( massive retaliation ). Thus it was generally assumed that any combat in Europe would end with apocalyptic conclusions. MIRVed land-based ICBMs are generally considered suitable for a first strike (inherently counterforce ) or a counterforce second strike , due to: Unlike a decapitation strike or a countervalue strike , a counterforce strike might result in
402-509: A guaranteed second-strike capability because of their stealth and by the number fielded by each Cold War adversary—it was highly unlikely that all of them could be targeted and preemptively destroyed (in contrast to, for example, a missile silo with a fixed location that could be targeted during a first strike). Given their long-range, high survivability and ability to carry many medium- and long-range nuclear missiles, submarines were credible and effective means for full-scale retaliation even after
469-542: A massive first strike. This deterrence strategy and the program have continued into the 21st century, with nuclear submarines carrying Trident II ballistic missiles as one leg of the US strategic nuclear deterrent and as the sole deterrent of the United Kingdom. The other elements of the US deterrent are intercontinental ballistic missiles (ICBMs) on alert in the continental United States, and nuclear-capable bombers. Ballistic missile submarines are also operated by
536-558: A new arms race, forcing the USSR to spend an increasing proportion of GDP on defense—something which has been claimed to have been an indirect cause of the eventual collapse of the Soviet Union. Gorbachev himself in 1983 announced that “the continuation of the S.D.I. program will sweep the world into a new stage of the arms race and would destabilize the strategic situation.” Proponents of ballistic missile defense (BMD) argue that MAD
603-414: A nuclear war relatively unharmed. The true second-strike capability could be achieved only when a nation had a guaranteed ability to fully retaliate after a first-strike attack. The United States had achieved an early form of second-strike capability by fielding continual patrols of strategic nuclear bombers, with a large number of planes always in the air, on their way to or from fail-safe points close to
670-399: A perpetual stalemate. MAD has been invoked by more than one weapons inventor. For example, Richard Jordan Gatling patented his namesake Gatling gun in 1862 with the partial intention of illustrating the futility of war. Likewise, after his 1867 invention of dynamite , Alfred Nobel stated that "the day when two army corps can annihilate each other in one second, all civilized nations, it
737-517: A post-MAD environment. Russian refusal to accept invitations to participate in NATO BMD may be indicative of the lack of an alternative to MAD in current Russian war-fighting strategy due to the dilapidation of conventional forces after the breakup of the Soviet Union .

Though the Minuteman III of the mid-1960s was MIRVed with three warheads, heavily MIRVed vehicles threatened to upset the balance; these included the SS-18 Satan which was deployed in 1976, and was considered to threaten Minuteman III silos, which led some neoconservatives to conclude a Soviet first strike was being prepared for. This led to the development of
871-503: A practical nuclear weapon, anticipated deterrence as the principal means of combating an enemy with nuclear weapons. In August 1945, the United States became the first nuclear power after the nuclear attacks on Hiroshima and Nagasaki . Four years later, on August 29, 1949, the Soviet Union detonated its own nuclear device . At the time, both sides lacked the means to effectively use nuclear devices against each other. However, with

In the event of a Soviet conventional attack on Western Europe , NATO planned to use tactical nuclear weapons . The Soviet Union countered this threat by issuing a statement that any use of nuclear weapons (tactical or otherwise) against Soviet forces would be grounds for
1005-545: A safe way to deter continued even farther with the thought that nuclear weapons intended on being used for the winning of a war, were impractical, and even considered too dangerous and risky. Even with the Cold War ending in 1991, deterrence from mutually assured destruction is still said to be the safest course to avoid nuclear warfare. A study published in the Journal of Conflict Resolution in 2009 quantitatively evaluated
1072-481: A sane regard for the consequences, presents a strong case for proponents of BMD who seek a policy which both protect against attack, but also does not require an escalation into what might become global nuclear war . Russia continues to have a strong public distaste for Western BMD initiatives, presumably because proprietary operative BMD systems could exceed their technical and financial resources and therefore degrade their larger military standing and sense of security in
1139-473: A similarly dire portrait". A situation in which the United States might actually be expected to carry out a "successful" attack is perceived as a disadvantage for both countries. The strategic balance between the United States and Russia is becoming less stable, and the objective, the technical possibility of a first strike by the United States is increasing. At a time of crisis, this instability could lead to an accidental nuclear war. For example, if Russia feared
1206-443: A sole strategy, and that this form of deterrence was seen as one of numerous options in US nuclear policy. Former officers have emphasized that they never felt as limited by the logic of MAD (and were prepared to use nuclear weapons in smaller-scale situations than "assured destruction" allowed), and did not deliberately target civilian cities (though they acknowledge that the result of a "purely military" attack would certainly devastate
1273-457: A state with limited nuclear capability and was not planned to alter the nuclear posture between Russia and the United States. While relations have improved and an intentional nuclear exchange is more unlikely, the decay in Russian nuclear capability in the post–Cold War era may have had an effect on the continued viability of the MAD doctrine. A 2006 article by Keir Lieber and Daryl Press stated that

In 1959, the journal was run by the Center for Research on Conflict Resolution at the University of Michigan in Ann Arbor. When

As such, this type of weapon

The concept of MAD had been discussed in the literature for nearly a century before the invention of nuclear weapons. One of the earliest references comes from the English author Wilkie Collins , writing at the time of the Franco-Prussian War in 1870: "I begin to believe in only one civilizing influence—the discovery one of these days of

Had such systems been able to effectively defend against a retaliatory second strike , MAD would have been undermined. However, multiple scientific studies showed technological and logistical problems in these systems, including

If the United States had a guarantee against Soviet nuclear attacks, its critics argued, it would have first-strike capability, which would have been a politically and militarily destabilizing position. Critics further argued that it could trigger a new arms race, this time to develop countermeasures for SDI. Despite its promise of nuclear safety, SDI was described by many of its critics (including Soviet nuclear physicist and later peace activist Andrei Sakharov ) as being even more dangerous than MAD because of these political implications. Supporters also argued that SDI could trigger

2144-523: The MAD doctrine continues to be applied. Proponents of MAD as part of the US and USSR strategic doctrine believed that nuclear war could best be prevented if neither side could expect to survive a full-scale nuclear exchange as a functioning state. Since the credibility of the threat is critical to such assurance, each side had to invest substantial capital in their nuclear arsenals even if they were not intended for use. In addition, neither side could be expected or allowed to adequately defend itself against
2211-401: The MAD doctrine was and still is expected to be a tense but stable global peace. However, many have argued that mutually assured destruction is unable to deter conventional war that could later escalate. Emerging domains of cyber-espionage , proxy-state conflict, and high-speed missiles threaten to circumvent MAD as a deterrent strategy. The primary application of this doctrine started during

Relations between the United States and Russia were, at least for a time, less tense than they had been with the Soviet Union. While MAD has become less applicable for the US and Russia, it has been argued as a factor behind Israel's acquisition of nuclear weapons . Similarly, diplomats have warned that Japan may be pressured to nuclearize by

It was only with the advent of nuclear-powered ballistic missile submarines , starting with the George Washington class in 1959, that a genuine survivable nuclear force became possible and a retaliatory second strike capability guaranteed. The deployment of fleets of ballistic missile submarines established
2479-476: The United States and Soviet Union started to become a reality, theorists began to think that mutual assured destruction would be sufficient to deter the other side from launching a nuclear weapon. Kenneth Waltz , an American political scientist, believed that nuclear forces were in fact useful, but even more useful in the fact that they deterred other nuclear threats from using them, based on mutually assured destruction. The theory of mutually assured destruction being
2546-430: The United States could carry out a nuclear first strike on Russia and would "have a good chance of destroying every Russian bomber base, submarine, and ICBM." This was attributed to reductions in Russian nuclear stockpiles and the increasing inefficiency and age of that which remains. Lieber and Press argued that the MAD era is coming to an end and that the United States is on the cusp of global nuclear primacy. However, in

The doctrine of MAD was officially at odds with that of the USSR , which had, contrary to MAD, insisted survival was possible. The Soviets believed they could win not only a strategic nuclear war, which they planned to absorb with their extensive civil defense planning, but also

These findings led to theory that MAD would still occur with many fewer weapons than were possessed by either the United States or USSR at the height of the Cold War. As such, nuclear winter was used as an argument for significant reduction of nuclear weapons since MAD would occur anyway. After the fall of

The tactic was expensive and problematic because of the high cost of keeping enough planes in the air at all times and the possibility they would be shot down by Soviet anti-aircraft missiles before reaching their targets. In addition, as the idea of a missile gap existing between

MAD may not apply to the situation in North Korea because the theory relies on rational consideration of the use and consequences of nuclear weapons, which may not be the case for potential North Korean deployment. Whether MAD was the officially accepted doctrine of the United States military during the Cold War is largely a matter of interpretation. The United States Air Force , for example, has retrospectively contended that it never advocated MAD as

3216-442: The era of nuclear stability". MAD does not entirely apply to all nuclear-armed rivals. India and Pakistan are an example of this; because of the superiority of conventional Indian armed forces to their Pakistani counterparts, Pakistan may be forced to use their nuclear weapons on invading Indian forces out of desperation regardless of an Indian retaliatory strike. As such, any large-scale attack on Pakistan by India could precipitate

3350-837: The inability to distinguish between real and decoy weapons. The multiple independently targetable re-entry vehicle (MIRV) was another weapons system designed specifically to aid with the MAD nuclear deterrence doctrine. With a MIRV payload, one ICBM could hold many separate warheads. MIRVs were first created by the United States in order to counterbalance the Soviet A-35 anti-ballistic missile systems around Moscow. Since each defensive missile could be counted on to destroy only one offensive missile, making each offensive missile have, for example, three warheads (as with early MIRV systems) meant that three times as many defensive missiles were needed for each offensive missile. This made defending against missile attacks more costly and difficult. One of

The multiple warheads made defense untenable with the available technology, leaving the threat of retaliatory attack as the only viable defensive option. MIRVed land-based ICBMs tend to put

The term "mutual assured destruction", commonly abbreviated "MAD", was coined by Donald Brennan, a strategist working in Herman Kahn 's Hudson Institute in 1962. Brennan conceived the acronym cynically, spelling out the English word " mad " to argue that holding weapons capable of destroying society was irrational.
