Russia Updates Nuclear Doctrine as Ukraine Deploys Western Long-Range Missiles

Moscow has officially lowered its threshold for the use of nuclear weapons, a strategic shift that follows Ukraine's first reported use of U.S.-made ATACMS missiles to strike targets within Russian borders. The revised doctrine, signed by President Vladimir Putin, stipulates that a conventional attack on Russia by a non-nuclear state, if supported by a nuclear power, will be viewed as a joint assault. Western leaders have largely dismissed the move as an attempt to intimidate Kyiv's allies, while Kremlin officials describe the update as a necessary alignment with current security realities. Despite the heightened rhetoric, international observers note that the practical implications for the battlefield remain uncertain. The development has prompted calls for restraint from global leaders at the G20 summit, as markets monitor the potential for further escalation in the nearly three-year conflict.
