Too much emphasis on ancestral not enough on homeland. Despite what may have taken place 200 2000 or 20000 years ago to lead to the settled population being what it was when israel got Wished into existence, there was a population settled there. israel doesnt get to say it has a right to defend itself/right to exist when its defense now and existence in the first place is a function of the displacement of that population.
By the logic israel uses, the native Americans had no claim to the land because manifest destiny. They werent using it correctly either, the land is in much better hands now, gestures broadly. Also, those pesky indians were fighting among themselves so often the land changed hands countless times over the centuries and millennia; who’s to say who the rightful owners of the lands really were when the white savior came along and fixed it all up proper? They were wrong to try to defend the land their forefathers had hunted buffalo across, to launch failed wars to retake those lands, to form war councils to lead their people who recommended to commit acts designed to strike terror into the hearts of their oppressors like torture, kidnapping, raping settlers, and sending murderous raiding parties into border towns… Anyway, they couldnt defend it, so what claim can they be said to have had at all?
Now replace native american with palestinian, manifest destiny with zionism, hunted buffalo with farmed dates, war council with hamas, murderous raiding party with O7, and white savior with the 1947 U.N. Palestine Plan. Its just ethnic cleansing by way of genocide in order to take land and increase material wealth. There is no piece of paper that makes the harm done tit for tat for tit for tat going on nigh a century now any the less evil, and no matter how you slice this pie, israel comes out with a greater share of that evil, both for the initial wrong, and for the continued encroachment, coming full circle to the point I was making in my top level comment: Israel was founded by the foreign seizure of already settled lands. Observe in the “1947 U.N. Palestine Plan” UN is the subject and Palestine is quite literally objectified.
