Russia updates nuclear doctrine to allow response to conventional attacks

Russia has updated its nuclear doctrine, signed by President Vladimir Putin, which now allows for a nuclear response to conventional attacks supported by nuclear powers. This change follows recent strikes in Russian territory, reportedly involving U.S.-supplied missiles to Ukraine. The revised document outlines specific scenarios for nuclear use, including aggression against Russia or Belarus with conventional weapons. It emphasizes that any attack involving a nuclear power will be viewed as a joint aggression against Russia. Kremlin officials have indicated that these changes could lead to a nuclear response if Ukraine continues to strike Russian territory. However, U.S. officials have stated there has been no change in Russia's nuclear posture that would require a shift in their own strategy.
