well for one thing when modern Israel was established, nobody lived there, it was just a desert with some Palestinians on it. Some orthodox do not accept modern Israel as anything other than another country since it was created by man.
Then i'm sure the incoming Israelis got a good deal, per acre, when they bought desert land from the few who MAY have had claim on the land, perhaps because the latter MAY have purchased the land from someone before them. I'm sure they were compensated. Perhaps there was some abandoned desert land also that found better caretakers.
I am suggesting we might not have the Mohamet problem were it not for the holy books of Hebrew literature, which were incorporated into Christian holy books, as if any of what is described there is/was justified.
Looking at it from a martial perspective, Mohammeeded took what seemed to work, from a priest-craft point of view, and, taking that psychological warfare aspect, included overt military operations in his quest to resist, and overtake Jewish and Christian lands, and any other land.
It's right out of the Judeo-Christian playbook, and really represents some kind of "karma".
That said, Muhemet's game-play is exponentially more evil, representing more of a scorched earth policy, rather than the more modern priest-craft policy of persuasion.
However, we must remember that there was a time, in the history of Israel, when they did conduct military operations in the name of their god.
Perhaps it was because they were oppressed everywhere else, and were living in a desert having escaped from Egypt.
Still, just about everybody was living in a desert in those days, and life itself was hard.
Does anybody, in the name of god, have the right to make life harder for anybody else, by taking their land, instead of buying them out at fair market value?
As a Christian, i don't know why you would want to get involved on the side of Israel for any bookish, or religious reasons.
If i excuse Israel in any way, it's because of a general sense of charity, and fairness.
Theoretically, there are many Mohammmmeed bandito ruled areas that a follower could go to feel at home, and perhaps purchase some land. But apparently none of those places are good enough for many of the bookish types of left-over banditos.
As a general rule, if you make this globe, this "world" a "home", you will suffer.
One reason is because this is actually the proverbial hell.
Personally, i don't own land, and can't own land in a couple of my favorite places.
But there is only one reason i might "buy" land, and it would NOT be to make this world a "home".
