@Tacitus, the question that I'm asking myself right now is: are you unable to or maybe unwiling to understand what I wrote so far. I think it's a mixture of both things.
I'll keep explaining those basic things cause it may reach some more perceptive readers at some point.
Germany wishes to see Eastern Europe prosper
Well, Poland lies in Central Europe geographically and geopolitical, but that's not the point. For me Germany was never a truly Western country anyway. But those are our personal opinions, irrelevant to the matter.
Yes, Germany would like Central Europe to prosper to the point where it could become a large market for German products but not to the point where it could become a fully developed competitive economy
. Thinking otherwise would be insulting to Germans and their pragmatic ways
This approach may work with Czech or other smaller countries but Poland is just too big and to ambitious to settle down for such a position. It was a temporary solution when the economy was rebuilding after communist times but it was inevitable that one day such a position would not be suitable for Poland any longer. I hope it's clear so far?
So what to do now, how to solve this problem from a German point of view? How to deal with those bloody Poles, who on top of that have invited Americans into taking a more active role in Europe? I mean, blocking Ribentropp-Molotov pipe with Russia, starting some geopolitical initiatives, like 3SI, in central Europe without asking Berlin first? Who they think they are?
In the "good old days" Germany would make a preventive strike in order to jeopardize Polish plans. But these days it is impossible for Germany to do so for various reasons. So there are only some political and economic ways which you can use against Poland. Here's a sample:
"Countries such as Poland and Hungary must be starved financially,"
but come on, such words as "starving Poland" in the mouth of a German politician sounds very inappropriate
to say the least. That's not the way. And not pragmatic at all to reveal German plans so openly.
