The Crimean principle

The Crimean regional government in the Ukraine plans to hold a referendum, to leave Ukraine and join the Russian Federation, amongst its predominantly Russian-speaking population. The Russian parliament has voiced its over-whelming support for the idea.

Gary Kasparov, former world chess champion and member of the Russian opposition, points out that the same principle could apply to Kaliningrad.

Geographically isolated from the rest of Russia, Kaliningrad — formerly known as Königsberg — was part of Germany (East Prussia) until annexed by Josef Stalin at the end of WWII.
