What are you, a determinist?
The intifada has attempted to accomplish the flight of the Jews from their state by murdering as many Jews as possible and Israel's destruction so that the Palestinians could establish their state on Israel's ruins. Perpetrating ethnic cleansing or genocide to create a homeland is not a legitimate national aspiration.

As for pre-state Israeli terrorism, the dominant Zionist movement's (Labor's precurssor) paramilitary group engaged in it far less than their rightwing counterparts did. Labor's followers were the majority back then and they weren't terrorists. In any case, these paramilitaries never intended nor attempted to commit genocide on the local Arabs.

The intifada should be over, especially now that Arafat is gone. Hopefully Abu-Mazen will have the sense to call it off in the foreseeable future. The longer it lasts, the more the Palestinians will have to wait until they can establish their state west of the Jordan and the more they'll undergo hardships at the hands of Israel they wouldn't have had to suffer had they not unleashed that murder campaign.
