"So T-bird: all those "leaders" have been elected by a unanimous vote?" - Greg F

No Greg at least not in Israel where political parties of more than one persuasion are allowed to stand for election, but even with the vote in a democratic process in Israel the coalitions formed look to Israel's security first and foremost.

Now in "Palestine" on the other hand even on the rare occasions that they have elections the results tend to be ignored and the side with the most firepower in the area wins and having got into power then find reasons to cancel all future elections.
