Halting the Return of Nuclear Testing

 

 

8 November 2025

This week, we released a Network Members statement warning that a return to nuclear testing threatens global stability. Sahar Khan and Haleema Saadia argue that Trump’s nuclear testing announcement has presented India and Pakistan a rare moment of normative leadership to jointly reaffirm their nuclear moratoriums.

As always, we highlight recent activities from our network, including analyses on Trump’s decision to resume nuclear testing, Singapore’s foreign policy, South Korea’s dual-track approach to diplomacy, and nuclear safeguards cultures.

A Return to Nuclear Testing Threatens Global Stability

Over 60 APLN network members have signed a statement calling on President Trump to reverse any decision to resume nuclear testing and for all leaders to exercise restraint in how they discuss nuclear weapons issues.

The statement warns that resuming nuclear testing would heighten instability at a time when restraint and dialogue are urgently needed. The signatories caution that such a move could embolden other nations to pursue their own nuclear weapons programs and further erode the global non-proliferation regime. They urge leaders of nuclear-armed states to reaffirm their commitment to the nuclear testing moratorium.

The signed statement is available in English, Chinese, Korean and Japanese.

Responsibility Over Rivalry: Why India and Pakistan Should Reject Nuclear Testing

Sahar Khan and Haleema Saadia argue that President Trump’s decision to resume US nuclear testing risks triggering a new global arms race, pressuring India and Pakistan to reconsider their testing moratoria. While renewed testing might offer limited technological benefits, it would carry major diplomatic and strategic costs for both countries. Instead, India and Pakistan should jointly reaffirm their commitment to a nuclear testing moratorium to strengthen their standing as responsible nuclear powers.
