We have two relations called " Judea and Samaria"
https://www.openstreetmap.org/relation/1803010 - This one excludes the East Jerusalem
https://www.openstreetmap.org/relation/1613659 - This one includes East Jerusalem
I propose we rename 1613659 into “west bank”.
Israel is divided into 7 legal districts. One of them is Jerusalem District, one of them is Judea and Samaria. East Jerusalem is part of the Jerusalem District, so Judea and Samaria should not include East Jerusalem.
Furthermore, according to Wikipedia " Judea and Samaria is the Israeli government term for the territory generally referred to as the West Bank, but excluding East Jerusalem".
