UN Observed International Day for the Total Elimination of Nuclear Weapons on 26th September 2025.

The United Nations (UN) observed the International Day for the Total Elimination of Nuclear Weapons on 26th September 2025. The day aims to raise global awareness about the dangers of nuclear weapons, promote disarmament, and encourage international efforts for a nuclear-free world.

      - On 26th September 2013, the United Nations General Assembly (UNGA) adopted resolution A/RES/68/32, officially designating 26th September each year as the International Day for the Total Elimination of Nuclear Weapons. The resolution underscores global commitment following UNGA’s first high-level nuclear disarmament meeting in 2013.

      - The inaugural International Day for the Total Elimination of Nuclear Weapons was celebrated on 26th September 2014, marking the beginning of annual global observances promoting nuclear disarmament.

      - NWFZs are regional treaties recognized by the UNGA (Res. 3472) to strengthen non-proliferation, promote peace, and ensure no nuclear weapons through defined boundaries and international verification. The first NWFZ was established in Latin America and the Caribbean (Treaty of Tlatelolco, 1967), followed by the South Pacific (Rarotonga, 1985), Southeast Asia (Bangkok, 1995), Africa (Pelindaba, 2006), and Central Asia (2006).

Main Point :-   Adopted in 2017 and effective from 22 January 2021, the TPNW is the first multilateral legally binding treaty in two decades banning all nuclear weapons activities. The treaty reinforces international commitment to a nuclear-free world.

      Key treaties include the original Strategic Arms Reduction Treaty (START, 1994–2009) between the USA and the Soviet Union. The New START Treaty is extended until 4 February 2026, though Russia suspended participation on 21 February 2023 and withdrew from the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on 2 November 2023.

As of 2025, approximately 12,241 nuclear weapons exist worldwide. Over 50% of the global population resides in countries with nuclear weapons or within nuclear alliances. The 3rd Meeting of States Parties to the TPNW, held from 3–7 March 2025 at UN Headquarters, adopted a declaration reinforcing global commitment to nuclear disarmament.
