Because of this German arrogance there isn't, and it won't be, good relations between our nations.
Spike - you seem to ba a smart guy. How can you say such a thing? No other country has helped Poland so much since 1989 as Germany has.
We had their full political support in our attempts to join the EU and NATO, we received substantial amount of money in structural funds, and other economic help. In 2002 they have given us 128 Leopard tanks with full equipment and ammunition; they were 15-year old, but they came from their military reserve, so they weren't used up or neglected - the market value of the equipment back then was over a billion zlotys, and we paid symbolic 1PLN for them. It introduced a whole new quality into our panzer forces. Everyone expected the tanks to be in very bad condition, but they were practically as new. We also got 23 MiG-29 fighters for a "symboliczna złotówka". Our farming in the west of Poland practically depends upon German new/used agricultural equipment. We get 50 billion euro surplus in trade exchange with Germany every year (they could very well buy those trains, gas turbines, engines or furniture elsewhere, but they get it from us - partly for economic reason, but partly as a part of their unwavering politcal/economical support). Just a couple of examples off the top of my head. I don't even want to imagine what would happen if our relations indeed turned bad one day.
Of course, there is the issue of Nord Stream, which is difficult, but apart from that Germany has been our most stable and dependable ally for the last 30 years
(and I can't say that about ANY other country in the world). Surely that must count for something!
