Russia warns NATO of possible nuclear response if Kaliningrad is cut off

Russia has warned NATO it is prepared to use its entire arsenal, including nuclear weapons, if the alliance attempts to blockade Kaliningrad, according to a diplomatic memo sent to NATO member states. The memo claims Moscow has information that NATO is planning an air and naval blockade of Kaliningrad. NATO Secretary-General Mark Rutte responded by calling the threats unhelpful and stated that Russia should stop nuclear threats, downplaying the seriousness of the situation.
