Like Snowstalker, I'm part Jewish * and I think trying to avoid debating the obvious issue is going to be an exercise in futility. In any event if such debate is forbidden it seems that in this series we're just going to end up with a kindler, gentler Israel that continues to massacre people but also has gay marriage or whatever or we decide that PEACE is magically reached by the 70s and we move on to discussing unique political issues like tax rates and transport policy.
*Note: not actually true but about as valid as Snowstalker's claim
If Meretz starts winning around 40% (as I hope it will) with the Arab parties to bring it at 50%, it's perfectly reasonable to assume peace will eventually end up being achieved with all interlocutors who seek it.
