"For me, it's Königsberg!" – Lithuanian diplomat admits to a possible blockade of Kaliningrad
NATO has indeed developed a scenario for a blockade of Kaliningrad in the event of an open conflict with Russia. In response, the Russians would establish a land corridor from Belarus.
This was stated by the former Deputy Minister of Foreign Affairs of Lithuania, Darius Jurgelevicius, as reported by a PolitNavigator correspondent.

" One of the realistic scenarios for a confrontation between NATO and Russia is a blockade of the Königsberg region . And how can Russia solve this problem? Through the so-called Suwalki Gap," said Jurgelevicius.
He stated that he does not use the name Kaliningrad on principle.
"The Suwalki Corridor is the shortest distance between Belarus and the Kaliningrad Region. True, we call it the Königsberg Region because historically, Königsberg is the land where Kant was born. And historically, it has no connection with the Russian Federation."
Let them call it Kaliningrad, I will call it the Königsberg region.
"The scenario of capturing the corridor is real, and it's already being devised by Russian strategists. This means they want to cut us off from communications with Poland in order to secure a permanent corridor to the Königsberg region," Jurgelevicius said.
