If you look closer at the artwork, though, you see that it shows a decidedly Jewish perspective on the Land of Israel. Judea and Samaria are noted; Shechem is on the map without using the name Nablus as it is currently referred to, current "settlements" of Bet El (Bethel) and Shiloh are listed, there is no "east Jerusalem."
This "pro-Palestinian" tweet proves that Jews are the indigenous people of the region, having been in the area far longer than any Muslims.
Joumblatt's caption was incomplete - it should have said "Palestine will remain the Jewish homeland forever."
