i dont have any friends anymore, and the few i had were indeed german.
believe me, there is not as much shame and remorse as there is an acceptance of a checkered past. there had been a massive immigration wave of refugees and dispelled persons especially from eastern european countries in the late 1940s after ww2. 14 mio people of german origin moved or were moved to the west, into what is germany today. hundreds of thousands did not survive it. i think this experience and stories about having lost a home and being forced to flee, are still prevalent and talked about in millions of families in germany. people prefer seeing themselves as victims, not so much as perpetrators, which is quite natural. this refugee experience, and thus an identification with current victims of political persecution, made many germans support the open-border-policy of merkel, i think.
i wouldnt doubt what you say about globalist mulitnationals' secret agenda and their efforts to instrumentalize and take advantage of the outcome of ww2. i read this very interesting book by robert pfaller called "language of adults" in which he argues similar to you, namely that a highly sensitive identity politics works hand in hand with the brutal exploitation of corporate mulitnationals. as long as we accuse each other of being racists, bigots, nazis, you name it, like children in a kindergarten, those in power can rub their hands as the principle of divide et impera has been implemented brilliantly.
