Functionally, probably? Given most states are sovereign instead of being divided up into zones by security checkpoints managed by a foreign power and which requires citizenship in said foreign power to cross. Between how much influence Isreal has in the government of the West Bank archipelago and the requirement that Palestinians possess a lower tier of Israeli citizenship in order to move from town to town, I don’t think a strong case can be made that the Isrealis have allowed the Palestinians have sovereignty over their own territory.

As such the Palestinian people of the West Bank have been and unfortunately practically remain part of the Israeli state, albeit a horribly discriminated and abused part of it with very good reason to splinter off into their own state. If Isreal had actually followed the UN mandate in the first place there might be a stronger argument that the West Bank and Gaza have always had a sovereign Palestinian government, but they functionally annexed them instead, and as such the West Bank and Gaza are now hopefully splintering off from the government they have been largely barred from participating in on racial grounds.
