Germany lost a significant amount of territory that has not been given back.[0] East Germany (and the whole of rest of Eastern Europe) to this day is much poorer than western parts thanks to half a century of Soviet occupation. I never hear anyone make demands for restitution regarding that bit of very recent history. Any way, the argument I was making was that at some point the blood clearly does wash off, and where you draw the line is arbitrary. Why should a white Australian feel guilty for the Frontier Wars but a German shouldn't feel guilty for the holocaust?
