more regional stability.
Without araft and his PLO terrorists coming to town, civil society in the judea and samaria is better off since the endemic corruption of fatah and the PLO is absent. Gaza still has a hamas problem and withdrawal might still occur, but not necessarily. The arab states would continue to use the conflict for internal benefit and brutalize and expel the palestinians (like jordan and kuwait, etc) when they engage in regime threatening behavior.
Islamic terrorism would still appear and the PLO would be cast into this category instead of being artificially legitimized through no positive action on their part and their cause would be local and irrelevant (think kurds, tibetens) ....
