Comparing South Lebanon to West Bank/Gaza is so simplistic and naive that one must immediately suspect anyone who makes such a comparison. UNIFIL did not stop the violence that led up to the recent Lebanon conflict, and their expanded presence has already been turned into a joke by the stand taken last week by Sheik Nasrallah. When both sides decide to take a break from fighting, the UN peacekeeping forces provide political cover. That is all they do, that's all they have ever done, and that is all they will ever do. The palestinian paramilitary forces (as opposed to the political eunuchs like Abbas and Hamiyeh) have not been hurt bad enough to decide to stop fighting and neither has the IDF. Ergo-no place for "peacekeepers", because there is no peace to keep.
