About The Nuclear Non-Proliferation Treaty (NPT)

  • The NPT is a global treaty signed in 1968 and entered into force in 1970, aimed at:
    • Preventing the spread of nuclear weapons and technology
    • Promoting peaceful uses of nuclear energy
    • Supporting nuclear disarmament
  • Background: Post-World War II Nuclear Concerns
    • After the atomic bombings in Japan (1945), nations began a nuclear arms race.
    • Alongside, efforts emerged to limit the proliferation of nuclear weapons and technology.
  • Atoms for Peace Initiative (1953)
    • Launched by U.S. President Dwight D. Eisenhower
    • Advocated for the peaceful use of nuclear energy
    • Paved the way for the formation of the International Atomic Energy Agency (IAEA)
    • Introduced a safeguards system to monitor and verify civilian nuclear activities
  • Safeguards and Verification
    • Non-nuclear weapon states must submit detailed reports on nuclear activities
    • Allow IAEA inspections to prevent diversion of nuclear materials for weapons
    • Part of the “basic bargain”: peaceful nuclear assistance in exchange for oversight
  • Definition of Nuclear States under the NPT
    • Nuclear states are those that tested nuclear weapons before January 1, 1967.
    • This included:
      • United States
      • United Kingdom
      • France
      • Soviet Union (now Russia)
      • China
  • Membership and Non-Signatories
    • 191 countries are parties to the treaty
    • Non-signatories include:
      • India: Conducted nuclear tests in 1974; opposes the discriminatory nature of the treaty
      • Pakistan: Not a signatory
      • Israel: Neither confirms nor denies nuclear weapons possession; hasn’t signed
      • North Korea: Signed in 1985, withdrew in 2003, expelled IAEA inspectors
  • Criticism
    • Viewed as discriminatory for legitimizing nuclear weapons only for the P5 (UNSC permanent members).
    • The 1967 cut-off date is seen as arbitrary, reinforcing a nuclear hierarchy.

How Can a Country Leave the NPT?

  • Under Article 10 of the Nuclear Non-Proliferation Treaty (NPT):
    • A country may withdraw if extraordinary events jeopardize its supreme national interests.
    • It must notify all treaty parties and the UN Security Council three months in advance, citing those events.

Iran's NPT Membership and Recent Developments

  • Iran joined the NPT in 1970, prior to its Islamic Revolution (1979).
  • For the first time in nearly 20 years, the IAEA Board of Governors recently censured Iran, citing:
    • Repeated failure since 2019 to cooperate fully with the agency.
    • Discovery of undeclared nuclear material and activities at multiple sites.
  • Iran’s Response
    • Iran denied violations, stating it has adhered to its safeguards obligations under the NPT.
    • However, tensions have grown, particularly after recent Israeli strikes and Iran’s retaliatory missile attacks.

Implications of Iran Withdrawing from the NPT

  • End of IAEA Oversight
    • Iran would no longer be subject to IAEA inspections, which averaged 1.4 site visits per day in 2023.
    • This would reduce international visibility into Iran’s nuclear activities.
  • Risk of Destabilizing the Global Non-Proliferation Regime
    • Iran’s withdrawal could set a precedent for other states to follow.
    • Could lead to a weakening of global cooperation on nuclear non-proliferation.
  • Does Withdrawal Mean Weaponization
    • Leaving the NPT does not automatically imply Iran will build nuclear weapons.
    • However, historical cases (e.g., North Korea) show that withdrawal may precede weapon development.
    • Iran has denied such intentions, but regional instability fuels uncertainty.
  • Scholarly Perspective: The Value of NPT
    • Experts argue that:
      • Even imperfect adherence can significantly slow nuclear proliferation.
      • A global treaty can maintain pressure until a tipping point is reached, beyond which violations could lead to breakdown of normative constraint.
