Russia Updates Nuclear Doctrine Amid Ukrainian Use of Long-Range Missiles

President Vladimir Putin has formally lowered the threshold for Russia’s use of nuclear weapons, signing a revised doctrine that allows for an atomic response to a conventional attack by any nation supported by a nuclear power. The policy shift follows reports that Ukraine launched U.S.-supplied ATACMS missiles into Russian territory for the first time on Tuesday, targeting a munitions depot in the Bryansk region. While Moscow describes the move as a necessary adjustment to current security threats, Western officials have dismissed the decree as irresponsible rhetoric aimed at intimidating Ukraine’s allies. The escalation marks a significant turning point in the conflict, with international observers warning of heightened risks as both sides move into more aggressive tactical phases. Despite the tension, U.S. defense officials stated they have seen no immediate reason to adjust their own nuclear posture.
