The treaty de-legitimise ‘proliferation’ (production and transfer) of nuclear weapons, fissile materials and related technology by the non-nuclear weapon states (NNWS).
However, the five recognised nuclear-weapon states (NWS) — namely the US, Russia, the UK, France and China, can continue to possess nuclear weapons.
Objective of the NPT

The treaty is nearly universally accepted with just four nuclear states opting out of the treaty — India, Pakistan, Israel and North Korea, as India says there are structural flaws in the treaty and it favoured few states.
