Overview
- Russia sent a diplomatic 'non-paper' to NATO and had several embassies publish statements saying Moscow would be prepared to use "all means, including nuclear weapons" if the Kaliningrad region were cut off, a move reported across Western outlets on Wednesday.
- NATO replied in writing that it is a defensive alliance, strongly denounced the nuclear rhetoric and said its exercises do not threaten Russian territory, and Secretary-General Mark Rutte said there is no imminent threat to alliance soil.
- The Russian note explicitly warned of possible strikes on "decision-making centres" in NATO member states at the start of any conflict, language that Western officials called unprecedented since the Cold War.
- Lithuania described the messages as unfounded psychological pressure and Poland remains on high alert, while Western governments point to a pattern of Russian hybrid operations — sabotage, arson and covert incidents — that raise the danger of accidental escalation.
- Kaliningrad is a highly militarised Russian exclave between Poland and Lithuania that both projects force and creates logistical vulnerability, and analysts warn the exchange could force NATO to expand deterrence measures or risk sharper confrontation if provocations continue.
