Potential Resumption of Nuclear Testing by Major Powers Threatens Global Test Ban Regime
Recent developments suggest a potential end to the decades-long global moratorium on nuclear testing. While the Comprehensive Test Ban Treaty (CTBT) of 1996 has not formally entered into force, major powers have largely observed a moratorium. However, Russia recently de-ratified the treaty, and discussions in the U.S. indicate a possible return to testing to bolster nuclear deterrence. Such a move by the U.S. or Russia could trigger a domino effect, pressuring China, India, and Pakistan to resume their own nuclear tests, thereby upending the global non-proliferation architecture.
Key Points
- The CTBT (1996) prohibits all nuclear explosions but has not entered into force due to lack of ratification by key states.
- Russia de-ratified the CTBT in 2023, citing the need to mirror the U.S. stance.
- The U.S. has conducted the highest number of nuclear tests (1,030), followed by the Soviet Union (715).
- Resumption of testing could lead to a new nuclear arms race with long-term consequences for global security.
