Leaked: Putin's 'mini nuclear attack' plan as Russia fears NATO invasion of Kaliningrad?

Kremlin-linked sources cited by Bloomberg say Vladimir Putin is preparing to escalate the war after judging peace efforts to be effectively deadlocked, with Russia weighing more intense conventional ballistic-missile attacks on Kyiv and other Ukrainian cities. Some Russian officials reportedly see tactical nuclear weapons as a theoretical last-resort option if Moscow’s position worsens, but the report stresses there is no evidence that Russia is preparing a nuclear strike. Moscow increasingly casts Ukrainian long-range attacks as NATO-backed operations because Western states supply Kyiv with weapons and intelligence.
