Russia expands nuclear doctrine in response to US tensions

Russia has updated its nuclear doctrine, expanding the scenarios in which it might use nuclear weapons. This change comes amid rising tensions with the West, particularly following reports that the U.S. allowed Ukraine to strike deep into Russian territory. The new doctrine states that Russia could consider a nuclear response if it or Belarus faces significant conventional aggression threatening their sovereignty. Previously, nuclear use was primarily linked to nuclear attacks or existential threats from conventional attacks. Additionally, the updated policy includes responses to conventional attacks supported by nuclear powers and mass aerial assaults crossing Russian borders. This marks a significant shift in Russia's nuclear strategy, emphasizing deterrence against perceived threats.
