The fact is the British/UN gave a bunch of land to people that wasn’t really theirs to give. Nakba happened (which is illegal to even talk about in Israel) which was already a mass genocide/forced displacement). People alive today saw this happen. Watch the documentary Tantura to see some of the horrors by early Israelis (rapes, torture, killing people and feeding them their own genitals).
The point is: throughout most of modern history “Israel” has been invading Palestine. The fact that the UN recognized Israel in 1949 doesn’t matter… because that recognition required mass displacement and horrors to actually materialize.
Arab wars etc are a consequence of this. Sure maybe Israel won some of those. But one has to accept that the very conceptualization of Israel is rooted in genocide and displacement from the start. Many (or maybe most) states throughout history were formed this way I guess … Israel had the bad luck of doing it during a time that the human rights and morality of modernity was beginning to fully form.
