Your rhetorical question was "why the intifada started" as if you know to blame it on the Israelis. Well you are wrong again. Intifada number one was well orchestrated by Arafat from his hideout in Tunis. An uprising that was the outcome of manipulation of events by the PLO. In the case of both intifadas and a future 3rd as being bandied about by Abbas and Hamas, none will come to fruition as none have a solid base for its purpose.
