Poles chose boring stability over fascinating unpredictability.
It seems that Poles are finally sick to death of fighting others, fighting each other and finally decided to go with some stability.
if you rely on patting by your 'European partners' in your politics how are you going to win anything from them (appart for some symbolic gestures)
80 billion symbolic gestures goes a hell of a long way.
Bear in mind that Germany, since 1990, has done a hell of a lot for Poland. We saw how Germany fought for visa-free access for Poles into Schengen, we saw how Germany helped Poland gain access to the EU (indeed - it might not have been publicised much in Poland, but Germany made it very clear that the 2004 accession had to include Poland), how Germany helped Poland get into Schengen, etc etc.
And don't forget the vast amount of ignoring of Customs regulations by the Germans helped Poles in the early 1990's ;)
