Firstly, the situation in the West Bank is not analogous to the one in Gaza. Secondly, Gaza is what you get when you do things unilaterally. Thirdly, there are too many hands in the pot to allow Hamas/Iran to turn WB into Gaza. Finally, ultimately it really doesn't matter if the West Bank turns into Gaza/Hamas- this is not a valid argument against withdrawal from settlements- the security argument is just a fig-leaf for the fundamental ideological belief that WB/Gaza does not deserve to be a Palestinian state, because if the security argument were really the thing motivating the current disenfranchisement of Palestinians, then the proponents of this argument would understand that nothing threatens the security and well-being of Israel and Jews world-wide, internationally, internally, and psychologically, more than the systemic disenfranchisement of several million people. At the end of the day, Israel must pull out of West Bank, not because they feel it is safe, not because the Palestinians have suddenly declared their undying love for the Jews, or vice versa, for that matter, but because maintaining fuzzy borders is historically disastrous and occupying millions of people for 6 decades, even if you really don't like them, even if they really don't like you, is simply not morally justifiable. Let the Palestinians declare statehood and have their land, and if they keep attacking Israel, you can always go to war against them as you would against any other sovereign enemy nation. At least when nations are sovereign, they have sovereign interests. At least after a real war between nations, there can be a possibility of real peace.
