US may restart nuclear tests to match China's alleged 'low-yield' nuclear testing

The US signaled readiness to resume low-yield nuclear testing, ending a moratorium since 1992, amid rising tensions with China and Russia over alleged secret tests. US officials accused China and Russia of covert nuclear tests, which both countries deny, raising fears of a renewed nuclear arms race. The Comprehensive Nuclear-Test-Ban Treaty faces strain as international monitors struggle to detect very low-yield tests, and the treaty has not fully entered into force.
