Germany in general acknowledged past wrongs. Russia is in a full denial mode

Nature of Polish-German conflict is different then Polish-Russian conflict. In first case we speak of conflict where genocide, assimilation and extermination of one entire culture was included into primary motivation, side by side with mere looting and grabbing. It was organized in Rome, within Vatican and agreed with Germanic leaders. It later continued and whole process is known as Drang Nach Osten. It never ended actually.
With Russians is different. Poles and Russians, their elites, competed for the domination within Slavic world, to attract as much as possible client Slavic tribes into their dominion. That`s how started, speaking of last 1000 years. In that competition, where luck was changing for both sides, idea of genocide never existed. Motivation was control, rule, assimilation and domination. Sometimes dominated Poles, sometimes Russians. Shamefully, both pledged alliances with foreigners in order to achieve their aims.
So, how I see things, Poles and Russians are ok. In fact, they are both victims of Rome.
