During the long period when the Baltic nations (Estonia, Lativia, Lithuania) were unwilling parts of the Soviet Union, lots of Russian speakers moved there and settled in, without becoming acculturated. The Soviet Union has been gone for 21 years.
Two decades later the Russian speakers are still there as indigestible lumps in the Baltic populations, much like the French-speaking lump in Canada. The Associated Press/Yahoo News article says the Russophones are mostly located adjacent to the Russian and Belarus borders.
