"well, maybe because now we can talk about all Soviet crimes?" -- it would be more useful to everyone if Poles started talking about their crimes against Ukrainians, Belorussians, and Russians. Pretending to be an innocent victims is kinda old...
"maybe because Poland had claims on that pieces of land, and had no claims on German Reich?" -- learn history. Polish operational planning involved an offensive against East Prussia with the purpose of occupying it and incorporating into Poland. Ridiculous as it sounds in retrospect.
"Democratic nation cannot wage a war without a good reason." -- two stunning revelations. First is that Poland, as it turns out, was a democratic nation. Who would've known? Second, is that territorial claims are now a good enough reason to wage war.
