"Leaked Russian Military Files Expose Criteria for Nuclear Strike"

Leaked Russian military documents reveal the criteria for using tactical nuclear weapons, indicating a threshold lower than publicly admitted, with potential triggers including enemy incursion, destruction of strategic assets, and distrust of China. The documents also suggest a fear of Chinese attack in Russia's Far East, leading to military exercises near China, while experts believe Russia may have a higher threshold for using tactical nuclear weapons against Ukraine to avoid escalation with the U.S. or U.K.
