which gives the return of the survivors a slight legitimaticy for their re- occupation of part of the last land that they inhabited as a nation,
Except that in this case, the Jews had last occupied that territory some 1900 years ago***.
We can think of the complications that can be caused by a consideration of Australia. The white settlers in Australia argued that the "savages" that lived here had no legal right to the land and they were subsequently dispossessed. Not many years ago, the Australian High Court recognised that the original Australians DID HAVE A LEGAL OWNERSHIP TO THE LAND, after all, but they could not confront current ownership.
In Palestine, descendents of the owners of the first century, claim they have a legal right to ownership and can dispossess contemporary owners.
Do you wonder that this is a major problem?
Do you wonder that after 100 years of confrontation between Europeans and Muslims, each succeeding generation becomes more hostile to the west? Do you wonder why young hot-heads, aware of the injustices burdening their spiritual brothers, become more radical?
This is not a new problem, the problems go back more than 1000 years. The problems will still make life dangerous for the grand-children of today's new-born, because the Europeans do not get it.

***one small caveat - we do not know what the lowest level of people did at the time. Did they die somewhere else as refugees? Make new homes on some unused land somewhere? Or, did they give up their religion, left the phallus of the son(s) intact and re-enter the land, presenting as non-jewish? In that last case we would expect some genetic similarities between newly arrived Jews and the dispossessed peoples, now tagged as Palestineans. At least some genetic studies do show similarities. If that situation can be confirmed, then the Jewish/Palestinian problem can be see as brother attemtpting to dispossess brother:

Palestinians
Further information: Palestinian people#DNA and genetic studiesMany genetic studies have demonstrated that most of the various Jewish ethnic divisions and the Palestinians and other Levantines, like theDruze [12] [13] [18] [38] and Bedouin, [12] [13] are genetically closer to each other than the Palestinians or European Jews are to non-Jewish Europeans or Africans. [12] [13] [96] One DNA study by Nebel and colleagues found genetic evidence in support of historical records that "part, or perhaps the majority" of Muslim Palestinians descend from "local inhabitants, mainly Christians and Jews, who had converted after the Islamic conquest in the seventh century AD". [96] They also found substantial genetic overlap between Muslim Palestinians and Ashkenazi and Sephardic Jews, though with some significant differences that might be explainable by the geographical isolation of the Jews and by immigration of Arab tribes in the first millennium.
