Overview
- Foreign Minister Sergey Lavrov said Russia is ready to discuss U.S. accusations of secret underground blasts and pointed to global seismic monitoring to verify any nuclear detonation.
- Kremlin spokesman Dmitry Peskov said Moscow is still studying the practicability of preparing for tests and has not received clarification from Washington on what President Trump’s order entails.
- Lavrov reiterated that Russia would only mirror an actual nuclear weapons detonation, distinguishing it from subcritical experiments or delivery-system trials, which he noted are not banned.
- U.S. Energy Secretary Chris Wright said planned activity involves system and component checks without a nuclear explosion, and the Pentagon’s recent ICBM launch was routine and non-nuclear.
- Senate Democrats introduced the No Nuclear Testing Without Approval Act to require congressional sign-off and bar a U.S. nuclear detonation unless another state tests first, as Russia floated a one-year New START limits extension to cool tensions.
