Comprehensive Nuclear Test Ban Treaty (CTBT)
- The Comprehensive Test Ban Treaty prohibits “any nuclear weapon test explosion or any other nuclear explosion” anywhere in the world.
- The treaty was opened for signature in September 1996, and has been signed by 187 nations and ratified by 178.
- The treaty cannot formally enter into force until it is ratified by 44 specific nations, eight of which have yet to do so: India, China, Pakistan, North Korea, Israel, Iran, Egypt, and the United States.
- In order to verify compliance with its provisions, the treaty establishes a global network of monitoring facilities and allows for on-site inspections of suspicious events.
- Since the conclusion and opening for signature of the CTBT, nuclear testing has become taboo.
- Today, even those nuclear-armed states that have not signed or not ratified the CTBT, including India, Israel, and Pakistan, observe nuclear testing moratoriums.
- Only one country has conducted nuclear test explosions in this century, and even that country—North Korea—halted nuclear testing in 2017.
- Although the CTBT has not formally entered into force, the treaty has, for now, achieved its primary goal: ending nuclear weapon test explosions.
Why CTBT come into being?
- Between 1945 and 1996, more than 2,000 nuclear tests were carried out — 1,032 of them by the United States and 715 of them by the Soviet Union, according to the UN.
- Britain carried out 45 tests, France 210 and China 45.
- The radioactive fallout from those tests drew criticism from around the globe. The international community’s concern about the effects on health and the environment continued to grow.
- As a result, several attempts to curb the explosive tests were made.
- The 1963 Limited Nuclear Test-Ban Treaty (LTBT) was one of the first such attempts.
- It prohibited nuclear testing in the atmosphere, outer space, and underwater, but underground tests were still permitted.
- A major breakthrough only came after the Cold War ended around 1990 and the disintegration of the Soviet Union.
- As the geopolitical tensions simmered down, the UN took advantage of the situation and adopted the CTBT, which put a blanket ban on the explosive testing of nuclear weapons.
Effectiveness of CTBT
- Since the CTBT, 10 nuclear tests have taken place.
- India conducted two in 1998, Pakistan also two in 1998, and North Korea conducted tests in 2006, 2009, 2013, 2016 (twice) and 2017.
- The United States last tested in 1992, China and France in 1996 and the Soviet Union in 1990.
- Russia, which inherited most of the Soviet nuclear arsenal, has never conducted a nuclear test.
India’s Stand on CTBT:
- India’s decision to not sign the CTBT is primarily based on national security considerations.
- India views nuclear weapons as a deterrent against potential security threats from neighbouring countries, especially Pakistan and China.
- India also feels that signing the CTBT would undermine its national security and strategic autonomy, as it would constrain its ability to conduct nuclear tests.
- India’s decision is rooted in its desire for equitable and universal nuclear disarmament, as well as its national security concerns.
