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. 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. India has also adopted this strategy, which they term Minimum Credible Deterrence. 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 in 1971, when Pakistan started the war. Pakistan refuses to adopt No first use policy, while the other regional powers India and China had adopted the policy. Pakistan's foreign minister Shamshad Ahmad had warned that if Pakistan is ever invaded or attacked, it will use "any weapon in its arsenal" to defend itself. 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. Eliminating this perceived
