They are invalid because they were made by a puppet government and was limited to asking reparations from EAST GERMANY.
This is not true. The treaty specifically refers to Germany, not East Germany.
I found a German copy of the Treaty. The important part is here:
"Mit Rücksicht darauf, das Deutschlandseine Verpflichtungen zur Zahlung von Reparationen bereits in bedeutendem Maße nachgekommen ist und daß die Verbesserung der wirtschaftlichen Lage Deutschlands im Interesse seiner friedlichen Entwicklung liegt, [...] ".
This is not surprising, considering that back then, the GDR was in the eyes of the Warsaw Pact the only legitimate German government, just as the FRG was the only legitimate German state from the Western point of view. And as pointed out to you several times, claiming that the Polish government back then was not "legitimate" or a puppet is not an argument that is accepted in international courts.
They've paid out numerous parties like Greece that suffered way less loss of life and property than Poland and Poles.
True, but Poland received significantly more than e.g. Greece, even disregarding the lost German territory that are now Poland (which morally speaking should be included).
So why should Israel and Jews continue to receive money when Poles suffered roughly the same amount of death and destruction? .
Because Israel signed different treaties with Germany than Poland.
What happened in that meeting I do not know, but I know it occurred.
Based on what has transpired between Polish and German diplomats during the last two years, it is rather easy to predict how the meeting went. No doubt the Polish side admitted that there is no legal basis for their argument and that the government is just raising the issue for domestic reasons. They now try to find some sort of solution that helps Warsaw save face, most likely some sort of foundation.
There are only two ways how this will end:
a) Some sort of foundation where Germany donates maybe 1bn€.
b) Warsaw decides to escalate things for domestic reasons, goes to court, loses and claims that Germany had bribed the court and paints Poland yet again as victim of German plots.
We had to rebuild everything brick by brick and turned it into one of the highest nominal GDP eu members and an economy more competitive than the traditionally wealthy countries.
That is something Poland can be proud of.
