You have a basic misunderstanding of international law. One of the basics is that the people are "married" to the land.You need to read up on the basic rights of a people.
You need to be careful what you are claiming here. It sounds to me like you are claiming that possession of a territory grants superior or exclusive rights, regardless of how that possession was obtained. This argument is problematic on a number of levels, if you look at the laws surrounding international sovereignty, not the least of which is that Israel is currently in possession of Palestine.
We see this in the rule of nationality and state succession. When there is a change in governance, the people become citizens of the new state. They cannot be separated from their land.
The people have the right of territorial integrity. Land cannot be acquired through the threat or use of force. It is illegal to annex occupied territory. In other words, it is illegal to steal land.
The people are the sovereigns in a territory. People from another territory have no sovereignty there. Occupying powers do not acquire sovereignty in a territory. Whenever rights are mentioned, it is always the right of the people. It is never mentioned that states or governments have rights.
Governments derive their legitimacy by the consent of the governed. Governments established through coups or other military force are illegitimate.
Israel violates most or all of these legal principles.
I always get a chuckle when Tinmore offers his legal opinions by way of weed whacking through the landscape of wiki.
