The world has quietly achieved a significant milestone in history on January 14, 2026. It marks the longest period without a nuclear test since the Trinity test, lasting eight years, four months, and 11 days. This achievement is threatened by recent calls from the Trump administration to resume nuclear testing, which could jeopardize this fragile moratorium.
Nuclear testing has been a common practice since 1945, with over 2,000 nuclear weapons detonated by at least eight countries. The most recent test was conducted by North Korea in 2017, while other nuclear armed states conducted their last tests between 1990 and 1998. The Comprehensive Test Ban Treaty (CTBT) opened for signatures in 1996, aiming to ban all forms of supercritical nuclear testing. The United States, although signed but not ratified the treaty, has a responsibility to uphold its conditions to align with the global majority.
The taboo surrounding nuclear testing in the 21st century has been reinforced by the CTBT and public opposition. Advanced nuclear nations have suspended their test programs for over 30 years due to advancing technical capabilities. The need for full-scale explosive tests has diminished with non-nuclear experiments and advanced computation. The United States already tests its nuclear components extensively and has the tools for subcritical tests that provide detailed insights without the need for full-scale testing.
Public opposition to nuclear testing is strong, with communities affected by past tests opposing any resumption. The environmental and health consequences from previous tests have led to a unanimous resolution by the Nevada state legislature against nuclear testing. Calls for resumed testing are politically driven rather than technologically driven, as experts in charge of the nuclear arsenal express confidence in existing capabilities.
The current moratorium on nuclear testing is crucial for maintaining global stability. Reopening this Pandora’s box could lead to competition, instability, and uncertainty in an already precarious world. To support the moratorium, efforts like the RESTRAIN Act (HB 5894 and SB 3090) aim to prohibit nuclear explosive testing in the United States. It is essential to uphold the current ban on nuclear testing to ensure peace and security worldwide.
