Sorry to pee in the soup here, but I believe the butcher Sharon has ulterior motives in this.

The obvious thing that comes to mind is that the Gaza pullout is a bone thrown to the Palestinians to appease international pressure: "See, we gave them Gaza; we're good guys after all." This may well cement Israel's occupation of the much larger and more important West Bank (which includes Jerusalem, after all).

But it could go much deeper than that. I do not believe that Sharon would give the Palestinians the sweat off his balls unless he had some nefarious reason.

Cheers,
Michael
