I disagree that either palestine or israel could have done this without dubya.
1. Dubya refused to deal with a terrorist. (aka Arafat). He gave a much-needed dose of reality to the palestinians.
2. He openly called for a palestinian state. No leftist or european want to give him credit for that at all, seems to be forgotten in all this.
3. Sharon knew that dubya would support the fence and that he would support tough actions towards the terrorists.
As far as the Mavdog saying the wall "isn't up", that's as fancifal as Kerry's trip to cambodia at christmas. Complete refutation of reality. Or maybe it's the "nuance" speaking again, it's not 100% complete so it's not relevant, fantasy talk.
