The international community does not recognize "Judea and Samaria" as a jurisdiction. So the question is moot.
Further, what you're getting at is a question of sovereignty -- which has nothing to do with religious belief or cultural identity, per se. Which makes the question doubly moot.
Judea and Samaria are historical names and predate establishment of state of Israel and it administrative division. This naming is also used by UN and going back for example to 1947 UN Partition plan: "the boundary of the hill country of Samaria and Judea starts on the Jordan River...".
and i am not talking about sovereignty. i am talking about self determination per us charter. can jews do it there ? can samaritans do it there ? can palestinians do it there ?
Right, but that doesn't make them internationally recognized.
If you can't use valid jurisdiction names, there's nothing to talk about here.
