actually, the first and second intifada DID bring results:
1st intifida: before the first intifada the palis had ZERO rights, their own authority wasnt even recognized, and israel virtually controlled everything, as a result of the 2nd intifiada it finally brought some legitimacy and recognition for the Palestinians, the PA was finally recognized and backed, and the Palestinians gained some moderate independance as it allowed them to control their own cities and towns via the PA, whereas before the uprising no such thing ever existed, and was hardly on the cards.
2nd intifada: the 2nd intifada crippled the Israeli econamy, and brought much more coverage to the crimes and aggression of the Israelis, everyone was starting to forget about the area until the Palis rose up. furthermore thanks to the 2nd intifada the Israelis were forced to leave Gaza and abandon their settlements because it became futile to defend them from attack after attack, pretty much like what happened to Israel in south lebanon. if the 2nd intifada never happened gaza would still be under Israeli hands, and who knows, the Israelis would have probaly even extended their settlements.
hence anyone who says the 2 intifadas brought nothing or no success for the palestinians need to have their heads re-examined and need to check the facts, and get to reality.
