Yes, I know the history of the Middle East. At least we can agree that none of the Jewish/Israeli organizations/institutions you mention have anything in common, to what began with the PLO founding charter of 1964.
Incidentally, in this original PLO charter, the area of Arab occupation since 1948 is still called what it has been since the Bronze Age: “Judea and Samaria”. The term “West Bank” was only invented in the early 1970s for the purpose of delegitimization.
Jerusalem is not even mentioned in the PLO founding charter.
