Nuclear Armed Nations

Nuclear armed nations

9 nuclear armed states – US, UK, Russia, China, France, India, Pakistan, Israel, North Korea- possess approximately 12,000 nuclear weapons.  These arsenals, possessed by only a few countries, have the power to destroy the world as we know it many times over. Only 3% of their nuclear power could kill up to every 3rd person on earth.

Nuclear Abolition

IPPNW Global Network

IPPNW global federation against nuclear weapons

Around the clock, IPPNW affiliates are working to rid the world of the nuclear threat. Our affiliates know that the only answer to this existential threat is total abolition. We are hard at work to achieve this reality through the UN Treaty on the Prohibition of Nuclear Weapons.

    Donald Trump’s war of choice in the Middle East is but the latest indication that the system of international law―which provides guidelines for the behavior of nations in world affairs―is crumbling. In the late nineteenth and twentieth centuries, after thousands of years of violent international conflict, efforts to establish global norms for nations in connection

  • War on Iran: nuclear consequences
    by Xanthe Hall on March 6, 2026 at 8:06 pm

    President Donald Trump declared in his State of the Union address that he would see to it that Iran would never get a nuclear weapon. He had previously claimed that the strikes in 2025 had “obliterated” Iran’s nuclear programme, although there is evidence that the destruction might not have been as absolute as he claimed.
