According to this analysis, Russia has been acting as a status quo power, trying to preserve the balance of power after the Soviet collapse. People in the West may agree or disagree whether this was a desirable state of affairs. Some people in Washington will not be happy until Russia is pushed back beyond its 1780 borders. But an objective realist would probably conclude that Russia was behaving like any other status quo power. But recent developments have made this realist perspective itself look quaintly anachronistic. It seems to have been displaced by a new approach which will be far more tricky for the West to deal with.
