Do you have any ideas why Estonia, Latvia, Lithuania and Poland not like Russia in general so much? If we look at Georgia conflict, goverment of this countries was on Georgia side...

Russia is seen as the old 'colonial power' in many East European countries, and there is no love lost between most of them and Russia.

Through history, Russia or the Soviet Union have been dominating these small countries which just acquired independence recently, and there will be a long period of recrimination and hostility before relations will be more cordial.

That is the fate of ex-colonial powers, just like France, Spain or Britain had with their old possessions.
