What if after the dissolution of the USSR, Russia had keep a thin strip of land connecting it with kaliningrad, psible between poland and lithuania?
Ups, @CalBear could move this thread to post-1900, please?Seems unlikely, considering you posted in the pre-1900 forum you could just have the Russian assimilate the area during the 19th century and have the Baltic states stay under a Russian state to this day and have them take over Königsberg during a big war against Prussia/Germany.
