Which treaty aims to prevent the proliferation of nuclear weapons?

The Nuclear Non-Proliferation Treaty (NPT) is designed to prevent the spread of nuclear weapons and promote the peaceful use of nuclear energy. It establishes a framework for countries to work towards disarmament, non-proliferation of nuclear weapons, and the right to peacefully use nuclear technology. This treaty is crucial in international efforts to control nuclear arsenals and prevent the increase of nuclear-armed states.

The Strategic Arms Reduction Treaty focuses on the reduction of existing nuclear arsenals between specific countries, while the Comprehensive Nuclear-Test-Ban Treaty is aimed at banning all nuclear test explosions. The Paris Agreement, on the other hand, pertains to climate change and does not address nuclear proliferation directly. Therefore, the NPT stands out as the key treaty aimed specifically at preventing the proliferation of nuclear weapons.
