Summary:
The article discusses the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) and the current challenges it faces. While the CTBTO has built a global monitoring system that effectively detects nuclear tests and enjoys widespread support, the treaty itself hasn’t entered into force due to the lack of ratification by key countries. Recent events, especially the threat by the former U.S. President Trump to resume nuclear testing, and Russia revocation to observing moratorium pose a serious threat to the CTBTO’s future and the global nuclear test ban. The article highlights the importance of the CTBTO’s monitoring capabilities and its role in maintaining transparency, even as the political landscape remains uncertain.

Global Nuclear Test Ban Treaty Threatened by Renewed Testing Concerns
Vienna, Austria – November 9, 2025 – The Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO), the international body dedicated to verifying a global ban on nuclear explosions, faces a renewed threat as major powers reconsider their commitment to the moratorium on nuclear testing.
Despite its success in establishing a sophisticated global monitoring system – the International Monitoring System (IMS) – the CTBT has not formally entered into force. Eight key nations, including the United States, China, Russia, India, and Pakistan, have yet to ratify the treaty, hindering its legal effectiveness.
The organization’s de facto verification regime built, tested, and provisionally operates, is the Vienna-based CTBTO Preparatory Commission, which today runs the system that would underpin a future treaty in force.
Former U.S. President Donald Trump’s recent suggestion to resume nuclear testing to keep up with China and Russia has sparked international concern. Analysts warn that such a move could trigger a new round of testing by other nuclear-armed states, undermining the CTBTO’s mission.
“A resumption of testing by the U.S. would have a paradoxical effect,” explained a CTBTO spokesperson. “While our system would detect and analyze any such test, it would also signal that the global moratorium is not secure.”
Russia’s revocation of its ratification in 2023 further weakened the treaty’s legal standing.
The CTBTO’s IMS, a network of 337 facilities worldwide, continuously monitors for nuclear explosions. It has proven its effectiveness by detecting North Korea’s nuclear tests and providing valuable data for tsunami warnings and other scientific research. The IMS has also expanded the IMS’s scientific uses, including for tsunami warning and atmospheric research, strengthening the system’s constituency across governments and research communities and making abrupt abandonment more expensive.
Experts emphasize that the CTBTO’s monitoring capabilities and the transparency it provides remain crucial for maintaining the global test ban. The organization’s ability to deliver reliable data on any nuclear activity remains the most tangible path toward achieving a legally binding and universally respected test ban regime, according to officials.
Whether the CTBTO can withstand these political challenges will depend on the decisions made in Washington, Moscow, Beijing, and other world capitals. The organization hopes that its continued delivery of timely and accurate data will ultimately persuade these nations to embrace the goal of a world free from nuclear testing.
