Russia has gotten a lot of mileage out of claims about ethnic Russians in the Baltic States. Those claims become less true with every passing year. Paul Goble reports that most ethnic Russians in Estonia are now loyal to Estonia, even if they speak only Russian.
That’s consistent with what I saw in the early 2000s. Many ethnic Russians who were uninterested in Estonian citizenship were older people who wanted to stay where they had always lived and did not care about voting or a passport to travel. They are dying off now, and more and more ethnic Russians have grown up in a free Estonia, part of the European Union.
