Russia is signaling potential changes to its nuclear doctrine in response to Ukraine's ongoing incursions into its Kursk region. Deputy Foreign Minister Sergei Ryabkov stated that adjustments are being made due to perceived Western "escalation." Russia accused the West of supporting Ukraine's cross-border raid that captured nearly 500 square miles of Russian territory, a claim denied by Ukraine's NATO allies. Analysts believe the likelihood of Russia deploying tactical nuclear weapons remains low, viewing the statements as a form of nuclear saber-rattling aimed at deterring Western support for Ukraine.
