Why in News?

Russia has recently indicated that it is moving towards revoking its ratification of the Comprehensive Nuclear Test Ban Treaty (CTBT).

What is the Comprehensive Nuclear Test Ban Treaty (CTBT)?

  • Genesis of the CTBT:
    • The CTBT is a multilateral treaty aimed at banning all nuclear explosions, whether for military or peaceful purposes.
    • The roots of the CTBT can be traced back to the Cold War era when the United States and the Soviet Union were engaged in a nuclear arms race, conducting numerous nuclear tests.
      • Between 1945 and 1996, over 2,000 nuclear tests took place globally, with the U.S. conducting 1,032 tests and the Soviet Union conducting 715 tests, among others.
    • In response to concerns about the environmental and health impacts of nuclear tests, the international community made efforts to limit testing.
    • The Limited Nuclear Test-Ban Treaty (LTBT) of 1963 prohibited nuclear testing in the atmosphere, outer space, and underwater but allowed underground tests.
    • The Threshold Test Ban Treaty (TTBT) of 1974 prohibits underground nuclear weapons tests and establishes a nuclear "threshold," yet it falls short of providing a comprehensive ban on all nuclear testing.
  • Breakthrough with the CTBT:
    • The end of the Cold War and the dissolution of the Soviet Union created a conducive environment for comprehensive arms control measures.
    • The CTBT was negotiated at the Conference on Disarmament in Geneva in 1994.
    • In 1996, the United Nations adopted the CTBT, which imposed a complete ban on nuclear weapons testing, closing the gaps left by previous treaties.
    • The CTBT became available for signature in September 1996, signifying a major advancement in the global endeavour to halt nuclear testing across the world.
      • The CTBT will enter into force 180 days after it has been ratified by all 44 states listed in Annex 2 to the treaty, which are states that possessed nuclear reactors or research reactors at the time of its adoption.
  • Current Position:
    • It has been signed by 187 nations and ratified by 178. However, the treaty cannot formally enter into force until it is ratified by 44 specific nations. Eight of these nations have yet to ratify the treaty:
      • China, India, Pakistan, North Korea, Israel, Iran, Egypt, United States.
