They happen to be the name of these geographical areas from "time immemorial" at least to people who have any respect to history, at least their own, outside of the political term "the West Bank" which was given to these territories after 1948, after Jordan occupied the area. Or would you tell me that the Samaritans, a small minority living in Samaria, who are named after this geographical area (unlike the Palestinians who have been named after a Roman name... Arab Romans?!) don't exist either? Welcome to a History Lesson. See, Zionists might have their own follies but obviously anti-Zionists are not immune to them either. The "West Bank" has been around for about 65+ years, as long as the state of Israel.
