This is exactly what will happen again and is why Israel is moving ahead with gaining more control over the region. Which is all historically Jewish land anyways.
Jewish people grew out of the Canaanites (https://en.wikipedia.org/wiki/Canaan) who occupied the region before the Philistines, who migrated there (Greek origin). There’s a lot of religious and cultural stuff that carried over from Canaanites to Israelites (and later to “modern” Jews).
Jewish people are Canaanites. Things about them have evolved over time - language, culture, etc - so they don’t call themselves that today. But they still share lots of commonalities with ancient Canaanites. And also they’re literally descendants of the Canaanites since Israelites were directly from the Canaanite population.
