This is exactly why the Jews were justified in seizing the land when they did, and why they’re still justified in killing the faux-Palestinian Muhammadans every time they ask for it.
With regard to “seizing the land,” I would refer you to Since Time Immemorial by Joan Peters. There weren’t all that many inhabitants of the land back in the mid-to-late 19th Century to contest our claims to this land. Basically, it was a sh!thole waiting to be taken.
