I don't even know what that means.
As far as I'm aware, in practice, the land "belongs" to whomsoever is governing it.
I'll leave that to nations squabbling with one another.
If we look at political maps of the world, we see that borders and nations are in a constant state of flux.
Ideally, nations should be governed by the people who reside in them in a democratic manner.
Saying that "Israel" must be governed by tribal Jews, even if it is against the majority's wishes, does not please G-d, imo. It is a recipe for disaster.
