Again, you are wrong. (My family also lived through the Nazi occupation and we were part of the post-War immigration from Europe.)  With specific reference to the Jewish holocaust, first there were the Nuremberg trials.  Then Nazi's were hunted around the world and brought to justice by Simon Weisenthal and others.  Battles over money and art treasures confiscated from Jews continue to the present day, and I believe an agreement had been reached recently with the Swiss government or banks on a settlement.
If, like many displaced persons of Eastern Europe, you were displaced from property, then you have a right to that property.  That that right can not be exercised does not illegitimate it. Of course, many DPs were Germans who first stole land, and then had it restored to their original owners after the war.
Do you, or do you not, believe that indigenous land claims and treaty rights may, in some circumstances, be just? Or do you think our natives should just "move on" from them.
