Are you serious? Throwing out Russians from K.??
Kaliningrad (former Königsberg, Eastern Prussia) is a result of WWII and expulsion of German population. After that the area was Russified (87%). Polish and similar are fractions of a percent.
Kaliningrad is a Russian stronghold, piling up nuclear rockets/weapons and all the nasty stuff.
What you describe IS the start of WWIII.
More dangerous than the Russian propaganda shout loud to close the gap (Suwalki gap).
