Types of nuclear warfare
The possibility of using nuclear weapons in war is usually divided into two subgroups, each with different effects and potentially fought with different types of nuclear armaments.
The first, a limited nuclear war (sometimes ''attack'' or ''exchange''), refers to the controlled use of nuclear weapons, whereby the implicit threat exists that a nations can still escalate their use of nuclear weapons. For example, using a small number of nuclear weapons against strictly military targets could be escalated through increasing the number of weapons used, or escalated through the selection of different targets. Limited attacks are thought to be a more credible response against attacks that do not justify all-out retaliation, such as an enemy's limited use of nuclear weapons.
The second, a full-scale nuclear war, could consist of large numbers of nuclear weapons used in an attack aimed at an entire country, including military, economic, and civilian targets. Such an attack would almost certainly destroy the entire economic, social, and military infrastructure of the target nation, and would likely have a devastating effect on Earth's biosphere.

). Some predict, however, that a limited war could potentially " escalate" into a full-scale nuclear war. Others have called limited nuclear war "global nuclear holocaust in slow motion", arguing that—once such a war took place—others would be sure to follow over a period of decades, effectively rendering the planet uninhabitable in the same way that a "full-scale nuclear war" between superpowers would, only taking a much longer (and arguably more agonizing) path to the same result.
Even the most optimistic predictions of the effects of a major nuclear exchange foresee the death of many millions of victims within a very short period of time. Such predictions usually include the breakdown of institutions, government, professional and commercial, vital to the continuation of civilization. The resulting loss of vital affordances (food, water and electricity production and distribution, medical and information services, etc.) would account for millions more deaths. More pessimistic predictions argue that a full-scale nuclear war could potentially bring about the extinction of the human race, or at least its ''near'' extinction, with only a relatively small number of survivors (mainly in remote areas) and a reduced

Either a limited or full-scale nuclear exchange could occur during an ''accidental nuclear war'', in which the use of nuclear weapons is triggered unintentionally. Postulated triggers for this scenario have included malfunctioning early warning devices and/or targeting computers, deliberate malfeasance by rogue military commanders, consequences of an accidental straying of warplanes into enemy airspace, reactions to unannounced missile tests during tense diplomatic periods, reactions to military exercises, mistranslated or miscommunicated messages, and others.
A number of these scenarios actually occurred during the Cold War, though none resulted in the use of nuclear weapons. Many such scenarios have been depicted in

Over a period of a few years, many in the American defense community became increasingly convinced of the invincibility of the United States to a nuclear attack. Indeed, it became generally believed that the threat of nuclear war would deter any strike against the United States.

Before the development of a capable strategic missile force in the Soviet Union, much of the war-fighting doctrine held by western nations revolved around using a large number of smaller nuclear weapons in a tactical role. It is debatable whether such use could be considered "limited" however because it was believed that the United States would use its own strategic weapons (mainly bombers at the time) should the Soviet Union deploy any kind of nuclear weapon against civilian targets.

Moreover, the Soviet Union could not afford to build any reasonable counterforce, as the economic output of the United States was far larger than that of the Soviets, and they would be unable to achieve "nuclear parity".
Soviet nuclear doctrine, however, did not match American nuclear doctrine. Soviet military planners assumed they could win a nuclear war. Therefore, they ''expected'' a large-scale nuclear exchange, followed by a "conventional war" which itself would involve heavy use of

In order to deliver a warhead to a target, a missile was much faster and more cost-effective than a bomber, and enjoyed a higher survivability due to the enormous difficulty of interception of the ICBMs (due to their high altitude and extreme speed).

For example, on 78 occasions in 1979 alone, a "missile display conference" was called to evaluate detections that were "potentially threatening to the North American continent". Some of these were trivial errors and were spotted quickly, but several went to more serious levels.

In nuclear strategy, a retaliatory strike or second-strike capability is a country's assured ability to respond to a nuclear attack with powerful nuclear retaliation against the attacker. To have such an ability (and to convince an opponent of it ...
" capability (i.e., after absorbing a "first strike"). Before the advent of the SLBM, thinkers feared that a nation might be tempted to initiate a first strike if it felt confident that such a strike would incapacitate the nuclear arsenal of its enemy, making retaliation impossible. With the advent of SLBMs, no nation could be certain that a first strike would incapacitate its enemy's entire nuclear arsenal. To the contrary, it would have to fear a near-certain retaliatory second strike from SLBMs. Thus, a first strike was a much less feasible (or desirable) option, and a deliberately initiated nuclear war was thought to be less likely to start.
However, it was soon realized that submarines could approach enemy coastlines undetected and decrease the warning time (the time between detection of the missile launch and the impact of the missile) from as much as half an hour to possibly under three minutes. This effect was especially significant to the United States, Britain and China, whose capitals of Washington D.C.,

However, this sub-strategic capacity has been criticized as potentially increasing the "acceptability" of using nuclear weapons. Combined with the trend in the reduction in the worldwide nuclear arsenal as of 2007 is the warhead miniaturization and modernization of the remaining strategic weapons that is presently occurring in all the declared nuclear weapon states, into more "usable" configurations.

suggests that this is creating a culture where use of these weapons is more acceptable and therefore is increasing the risk of war, as these modern weapons do not possess the same psychological deterrent value as the large Cold-War era, multi-megaton warheads.
In many ways, this present change in the balance of terror can be seen as the complete embracement of the switch from the 1950s Eisenhower, Eisenhower doctrine of "massive retaliation" to one of "flexible response", which has been growing in importance in the US nuclear war fighting plan/Single Integrated Operational Plan, SIOP every decade since.

weapons of mass destruction

.
Another dimension to the tactical use of nuclear weapons is that of such weapons deployed at sea for use against surface and submarine vessels. Until 1992, vessels of the United States Navy (and their aircraft) deployed various such weapons as bombs, rockets (guided and unguided), torpedoes, and depth charges. Such tactical naval nuclear weapons were considered more acceptable to use early in a conflict because there would be few civilian casualties. It was feared by many planners that such use would probably quickly have escalated into a large-scale nuclear war. This situation was particularly exacerbated by the fact that such weapons at sea were not constrained by the safeguards provided by the Permissive Action Link attached to U.S. Air Force and Army nuclear weapons. It is unknown if the navies of the other nuclear powers yet today deploy tactical nuclear weapons at sea.
The Nuclear Posture Review, 2018 US Nuclear Posture Review emphasised the need for the US to have sub-strategic nuclear weapons as additional layers for its nuclear deterrence.
Nuclear terrorism
Nuclear terrorism by non-state organizations or actors (even individuals) is a largely unknown and understudied factor in nuclear deterrence thinking, as states possessing nuclear weapons are susceptible to retaliation in kind, while sub- or trans-state actors may be less so. The collapse of the Soviet Union has given rise to the possibility that former Soviet nuclear weapons might become available on the black market (so-called 'loose nukes').
A number of other concerns have been expressed about the security of nuclear weapons in newer nuclear powers with relatively less stable governments, such as
Pakistan
Pakistan ( ur, ), officially the Islamic Republic of Pakistan ( ur, , label=none), is a country in South Asia. It is the world's List of countries and dependencies by population, fifth-most populous country, with a population of almost 24 ...
, but in each case, the fears have been addressed to some extent by statements and evidence provided by those nations, as well as cooperative programs between nations. Worry remains, however, in many circles that a relative decrease in the security of nuclear weapons has emerged in recent years, and that terrorists or others may attempt to exert control over (or use) nuclear weapons, militarily applicable technology, or nuclear materials and fuel.
Another possible nuclear terrorism threat are devices designed to disperse radioactive materials over a large area using conventional explosives, called dirty bombs. The detonation of a "dirty bomb" would not cause a nuclear explosion, nor would it release enough radiation to kill or injure a large number of people. However, it could cause severe disruption and require potentially very costly decontamination procedures and increased spending on security measures.
Radioactive materials can also be used for targeted assassinations. For example, the Alexander Litvinenko poisoning, poisoning of Alexander Litvinenko was described by medical professionals, as "an ominous landmark: the beginning of an era of

for being overly optimistic. CRP-2B, for instance, infamously predicted that 80% of Americans would survive a nuclear exchange with the Soviet Union, a figure that neglected nuclear war's impacts on healthcare infrastructure, the food supply, and the ecosystem and assumed that all major cities could be successfully evacuated within 3–5 days. A number of Cold War publications advocated preparations that could purportedly enable a large proportion of civilians to survive even a total nuclear war. Among the most famous of these is ''Nuclear War Survival Skills''.
To avoid injury and death from a nuclear weapon's heat flash and blast effects, the two most far ranging prompt effects of nuclear weapons, schoolchildren were taught to duck and cover by the early Cold War Duck and Cover (film), film of the same name. Such advice is once again being given in case of nuclear terrorism, nuclear terrorist attacks.
Prussian blue, or "Radiogardase", is stockpiled in the US, along with potassium iodide and DPTA as pharmaceuticals useful in treating internal exposure to harmful radioisotopes in fallout.
Publications on adapting to a changing diet and supplying nutritional food sources following a nuclear war, with particular focus on agricultural radioecology, include ''Nutrition in the postattack environment'' by the RAND corporation.
The British government developed a public alert system for use during a nuclear attack with the expectation of a four-minute warning before detonation. The United States expected a warning time of anywhere from half an hour (for land-based missiles) to less than three minutes (for submarine-based weapons). Many countries maintain plans for continuity of government following a nuclear attack or similar disasters. These range from a designated survivor, intended to ensure the survival of some form of government leadership, to the Soviet Dead Hand (nuclear war), Dead Hand system, which allows for retaliation even if all Soviet leadership were destroyed. Nuclear submarines are given letters of last resort: orders on what action to take in the event that an enemy nuclear strike has destroyed the government.
A number of other countries around the world have taken significant efforts to maximize their survival prospects in the event of large calamities, both natural and manmade. For example, metro stations in Pyongyang Metro, Pyongyang,

While the nuclear fallout shelters described above are the ideal long-term protection methods against dangerous radiation exposure in the event of a nuclear catastrophe, it is also necessary to have Radiation protection#Externally Penetrating Radiation Protective Equipment, mobile protection equipment for medical and security personnel to safely assist in containment, evacuation, and many other necessary public safety objectives which ensue as a result of nuclear detonation. There are many basic shielding strategies used to protect against the deposition of radioactive material from external radiation environments. Respirators that protect against internal deposition are used to prevent the inhalation and ingestion of radioactive material and dermal protective equipment which is used to protect against the deposition of material on external structures like skin, hair, and clothing. While these protection strategies do slightly reduce the exposure, they provide almost no protection from externally penetrating Gamma ray, gamma radiation, which is the cause of acute radiation syndrome and can be extremely lethal in high dosages. Naturally, shielding the entire body from high-energy gamma radiation is optimal, but the required mass to provide adequate attenuation makes functional movement nearly impossible.
Recent scientific studies have shown the feasibility of partial body shielding as a viable protection strategy against externally penetrating gamma radiation. The concept is based in providing sufficient attenuation to only the most radio-sensitive organs and tissues in efforts to defer the onset of acute radiation syndrome, the most immediate threat to humans from high doses of gamma radiation. Acute radiation syndrome is a result of irreversible bone marrow damage from high-energy radiation exposure. Due to the regenerative property of hematopoietic stem cells found in bone marrow, it is only necessary to protect enough bone marrow to repopulate the exposed areas of the body with the shielded supply. Because 50% of the body's supply of bone marrow is stored in the pelvic region which is also in close proximity to other radio-sensitive organs in the abdomen, the lower torso is a logical choice as the primary target for protection.Waterman, Gideon; Kase, Kenneth; Orion, Itzhak; Broisman, Andrey; Milstein, Oren (2017-09).
