"do you have a document from aboriginals of australia that surrender their land to you?" Terra nullis, Historian. Look it up. A legal trick cooked up by the British to pretend that there were no prior sovereign to the land. Not that I think very much of it, morally or legalistically, but it was deemed to be legal under International Law as it stood at the time. That's the thing about International Law, Historian - it isn't retrospective. What was legal THEN was legal THEN, and you could get away with it THEN, and if it isn't legal any more then ya' can't do it NOW. So, could Australia dispossess the people of, say, Fiji NOW? No, not a chance. Could Britain disposses the aborigines THEN? Yes, under terra nullis they could, and they did. I'll note that slavery used to be legal too, so why don't you point to that and say the Israel can enslave all the people it overruns. It'll save a lot of hassle.
