Background
Overview
UPSC frequently asks about India's nuclear doctrine, its stance on international treaties like NPT and CTBT, and the broader challenges of nuclear proliferation in the context of international relations and security.
Nuclear disarmament refers to the act of reducing or eliminating nuclear weapons, while non-proliferation aims to prevent the spread of nuclear weapons technology and materials to states that do not possess them. These efforts are central to international security and stability, addressing the existential threat posed by nuclear weapons.
