To insist on a kind of "justice" the Polish leadership is not able to enforce, leaves a very weak impression. It only reveals the actual insignificance of the Kaczynski brothers, since they are obviously unable to verify the effective importance of their country if they are forced to construct such moronic argumentations. WWII is over since 60 years and most of the participants (no matter if we speak about victims or offenders) are dust. It is boring to beat a dead horse*.
Although this time they are obviously still not among the decisive nations in Europe, the Poles could make a good deal since other, bigger and more powerful countries want to keep them in the boat. We (the other Europeans) all know that there will be a time without this funny Polish president and his twin brother. Therefore the whining of the twins might be a nuisance but is de facto irrelevant. Obviously a strange form of folklore.
* I do not deny the nameless crimes of German forces in Poland but I doubt their actual political relevance.
What Germany did, was shoot Polands horses, then argue that Germany should handle the transportation since Poland has no horses. Its that kind of arguement.
I had a better description of it in post #100.
