Russia Updates Nuclear Doctrine Following US Decision on Long-Range Missiles for Ukraine

Moscow has formally lowered its threshold for the use of nuclear weapons, a move that comes days after the United States authorized Ukraine to use American-made long-range missiles for strikes deep inside Russian territory. The updated doctrine, signed by President Vladimir Putin, states that an attack from a non-nuclear state backed by a nuclear power will be treated as a joint assault. While the Kremlin describes the move as a necessary adjustment to current security threats, Western officials have characterized the rhetoric as an attempt to deter international support for Kyiv. According to military analysts, the escalation marks a significant shift in the conflict's geopolitical landscape, though it remains unclear how these policy changes will manifest on the battlefield. International observers continue to monitor the situation as diplomatic tensions reach a new peak.
