The criteria for possessing nuclear weapons typically involve the country being recognized as a nuclear-weapon state under the Nuclear Non-Proliferation Treaty (NPT), having the technological capabilities to develop and maintain nuclear weapons, and having the political will to maintain a nuclear arsenal. However, possessing nuclear weapons is subject to international agreements and treaties, and there are restrictions and obligations associated with their possession.

Some argue that the threat of nuclear weapons deters countries from engaging in large-scale conflicts, thereby maintaining world peace. However, the possession of nuclear weapons also introduces the risk of accidental use, escalation, or non-state actors acquiring them, which can undermine world peace. Ultimately, nuclear weapons alone cannot guarantee world peace and must be complemented by diplomacy, cooperation, and conflict resolution.
Nuclear weapons provide protection against war. With the possession of a nuclear weapon, enemy states will be hesitant to attack due to Mutual Assured Destruction (M.A.D.), the belief that if a country attacks another state with a nuclear weapon, the targeted state with fire with a counter attack, assuring both nations will be significantly damaged.
