Political Memes

I mean, if you want to trace it back that far you're talking about the bronze age Canaanites, and arguably through them the Phonecians and Carthaginians would be better successors than the Israelites. If that's the case then the land should either be under Tunisian administration (for maximum cultural continuity after the fall of Carthage during the Punic wars) or either Turkey or Italy for political continuity through right of successive conquests. Or maybe we want to go with one of the theories about just how far afield the Phonecian diaspora went and consider the state of Utah their most direct modern descendent.

The ancient history of the levant is fascinating, but in the context of the current conflict over the nation of Israel it is relevant only in that it is a major part of Israeli nationalist mythmaking. If you want to actually trace who lived in the region thousands of years ago and where they ended up to determine who the "rightful" government should be you're going to end up in some really goofy places unless you already know what answer you want to get and are seeking justification rather than illumination. Hell, nationalism as a concept only dates back a few hundred years, and before then you're arguing about the competing claims of kings and empires through descent, conquest, oaths of fealty, and whatever else. Who ruled/owned/managed your land and who you were as a people were far less connected, and using that as a justification for modern government actions honestly sounds like they're out of actual justifications. It's just Putin ranting to Tucker Carlson about medieval maps for two hours while Russian troops shell Ukrainian cities.
