No, I don't think that'll help any. Sharon will just launch a full scale military occupation like he's always wanted, instead of the current halfway phase. This, in turn, will greatly increase the Palestinians' hatred of Israel, leading to more attacks. These will be used as justification for even harsher measures, until either the Israelis try a Final Solution or the Palestinians go for a full insurrection, backed by all of the other Arab nations, sparking yet another Arab-Israeli war. Either way, it's not good.
