I'm familiar with this point of view. I think maybe a third of Polish people share it, another third don't give a damn about Russians, yet another third think that it's vital for Poland to have healthy relationship w/ Russia. Even fore purely economical pragmatic reasons.

After the destruction of the USSR Poland became sort of a showcase. As a limitrof sitting in between Russia and Europe Poland can't afford always being pro-European or pro-Russian. It's being pro-Polish which means finding the right balance at the moment. Simply put, as long as Bruxelles has resources to support Poland Poland stays pro-European.

Seems like this year may be quite interesting in this regard.
