Putin confidant warns: Nuclear attack is “most likely” coming. Putin threatens to use nuclear weapons if Western troops fight in Ukraine.

Secret files show that Russia's threshold for nuclear war is lower than expected. Some 29 secret Russian military documents appear to contain discussions of tactical use of nuclear weapons and reportedly set operational thresholds for the first-use use of the weapons. “The Russian war of aggression in Ukraine has already been going on for two years,” says Alexander Gabuev, director of the Carnegie Russia Eurasia Center.
