Yeah, Germans were totally invited into Poland in 1939. Wait, then what's this https://en.wikipedia.org/wiki/World_War_II? Fuck off with your Nazi apologism.
What evidence would that be? The German state is a legal entity and it has its own obligations. Which includes obligations inherited from the states its a successor to. An obligation is pretty basic legal concept.
It is still the successor of that country. As such it's a direct continuation of an entity that was very much involved in the war and benefited from it at the expense of everyone the German people deemed to be subhuman filth. And it goes as far back as there is legal ground for it. There was legal ground for the reparations for war of aggression in 1940s and since there no expiration date on reparations, it will go on forever until the issue is resolved. Unlike stuff like slavery, since here is no legal framework for that.
Those are two different issues, so no. And I'm not sure why you brought up Prussia as no one mentioned it.
From Russia, not from Germany. For the land (more land that was given back) that Russia took for itself. Russia trading land with Poland (and trading is a generous term here since it's not like Poland had a choice) doesn't exactly resolve Poland's issues with Germany, does it?
"well i wanted to say sorry, i really mean it, let me buy you a new front door" was part of your comparison... Try to remember what you said yourself, could you? And Grandpa isn't dead. Federal Republic of Germany is successor state of the Third Reich. It's grandpa with a new coat of paint. Even if it was not the case, it'd still be Germany the grandchild benefiting from the money the Germany the grandpa stole. Proceeds of crime don't belong to the family of the criminal. Especially since it wasn't even laundered in this case. And Russia forcing decisions onto Poland under duress not only has no bearing on Poland, it's also void because of the duress.
Congrats on getting your knowledge from a video game while ignoring the earlier period. Teutonic Order was hired by Poland to deal with the conversion of Old Prussians, with the deal being they'd control those lands as vassals of Konrad I of Masovia. But while doing so, they accidentally annexed Dobrzyń Land Konrad I already gave to a monk order, without his knowledge or acceptance and when shit hit the fan, they shat on the whole deal and asked the HRE emperor to give the whole land to them as an independent state. That didn't pan out, but in the end the territory was split.
And Poland has always been the aggressor until the early 19th century? Never mind that by the very start of the 19th century didn't exist anymore, so no shit Poland was not aggressive in early 19th century. But it was the Teutonic Order who annexed Danzig territory from Poland. It was Teutonic Order that refused to give it back despite the pope ordering them to, then bribed France to force the pope to cancel that order some time later (since that was happening during the period of Avignon Papacy). 1327? Teutonic Order attacked Poland together with Mecklemburg and Bohemia. Followed by a period of Teutonic raids into Greater Poland and Kuyavia. Stopped only after a series of papal judgments that called the Order to return Pomerania (which they shat on each subsequent time). Great War of 1409? Started by Teutonic Order.
The first war started by Poland was in 1454 when Poland supported a burgher revolt. It ended with Teutonic Order returning the lands they stole earlier and kept illegally despite multiple popes telling them to fuck off from there (even though as a religious order they were ultimately subjects of the pope). The order also agreed to become a vassal of Poland, but that lasted only till the death of the current master. The following ones shat on their vassal obligations and eventually demanded the territory they lost as a result of the 1454 war, even though by papal verdicts it was never theirs. That forced Poland to war in Polish-Teutonic war of 1519-1521. After Teutonic Order lost it, they secularized and became Polish vassal for good.
That is, until Sweden steamrolled through Poland during the deluge (which, imagine that, was not started by Poland), when the following Duchy of Prussia smelled an occasion and broke their vassal oath, aiding the advancing Swedish forces. An interesting note, shortly before that happened, Prussian branch of the Hohenzollern died out, creating a personal union between Brandenburg and Prussia, in response to which many Prussian nobles asked the Polish king for full incorporation of Prussia into Polish-Lithuanian Commonwealth, to which he refused.
There were no further conflicts between Poland and Brandenburg-Prussia in the time it existed. Then it became the Kingdom of Prussia. The first war with Poland? Whoopty doo, they fought on the same side, in Russia-led coalition against Sweden. And after that there was no conflict until partitions of Poland, in which Poland was totes legit the aggressor, amirite?
Fuck off with your historical revisionism based on absolute squat.
