Nuclear-armed nations often invoke the theory of “nuclear deterrence” to justify maintaining nuclear arsenals. They argue that their weapons are solely for the purpose of deterring other nations from initiating a nuclear attack, and as such contribute to peace and stability.

Most nations, however, reject that logic and view nuclear deterrence as a dangerous, misguided and unsustainable approach to security. Moreover, it is inherently aggressive, as it relies on a constant, credible threat to inflict death and destruction on a large scale.

Contrary to the claims of deterrence proponents, the existence of nuclear weapons in the world has not prevented conflicts, including acts of aggression against nuclear-armed nations. In fact, nuclear weapons have made wars and confrontations more likely by exacerbating tensions and enabling coercion and blackmail.

Deterrence theory suggests that nuclear weapons are a legitimate and desirable source of security. This encourages proliferation and impedes disarmament.
