Also, I think it's unlikely Israel will annex the West Bank without extending citizenship to people living there. Obviously some people want it to happen but it's just not politically realistic (from the global point of view) in the modern age.
Israel already has de facto annexed the West Bank, tho I agree they won't annex de jure so they can continue to pay lip service to the two state solution that won't happen in my lifetime.
And somthat they do not have to extend citizenship...
Who said Transkei?
