Nuclear deterrent

Nuclear strategy involves the development of doctrines and strategies for the production and use of nuclear weapons.

As a sub-branch of military strategy, nuclear strategy attempts to match nuclear weapons as means to political ends. In addition to the actual use of nuclear weapons whether in the battlefield or strategically, a large part of nuclear strategy involves their use as a bargaining tool.

Some of the issues considered within nuclear strategy include:

Many strategists argue that nuclear strategy differs from other forms of military strategy. The immense and terrifying power of the weapons makes their use, in seeking victory in a traditional military sense, impossible.

Perhaps counterintuitively, an important focus of nuclear strategy has been determining how to prevent and deter their use, a crucial part of mutual assured destruction.

In the context of nuclear proliferation and maintaining the balance of power, states also seek to prevent other states from acquiring nuclear weapons as part of nuclear strategy.

The doctrine of mutual assured destruction (MAD) assumes that a nuclear deterrent force must be credible and survivable. That is, each deterrent force must survive a first strike with sufficient capability to effectively destroy the other country in a second strike. Therefore, a first strike would be suicidal for the launching country.

In the late 1940s and 1950s as the Cold War developed, the United States and Soviet Union pursued multiple delivery methods and platforms to deliver nuclear weapons. Three types of platforms proved most successful and are collectively called a "nuclear triad". These are air-delivered weapons (bombs or missiles), ballistic missile submarines (usually nuclear-powered and called SSBNs), and intercontinental ballistic missiles (ICBMs), usually deployed in land-based hardened missile silos or on vehicles.
