Kilobear, you know Gush Katif was not done for the sadistic purpose of torturing Jews. It was done because Sharon thought the pressure both from within and without was too great to withstand. From within, that many Israelis said how can we have 30,000 soldiers at risk protecting 8,000 settlers. From without, because international pressure even from the USA was getting too hard. Sharon may have felt if I give this up, then they will see how much I have done and we can hold on to the West Bank and Yerushalyim.
Recall that Rabban Yochanan ben Zakai saw that the pressure of the Romans was too great and he gave up YERUSHALYIM! He only asked for Yavneh vchachameha, a hatzala purta, knowing if he asked for more he would get nothing. Was he a bad man, too? You see we are in golus still. If you have questions, ask the RBSH, not Sharon, a mere mortal.
And here you are again with that famous self-contradiction: Zionism is no good because it is not Zionistic enough. The anti-zionists wanted to forego the entire state. You are upset now because we only have 95%?
Finally, if you wanted to keep Gaza, why not work on befriending and being mekarev the secular, and telling them that the RBSH will protect us, even despite the pressure, ki yachol nuchal lah. Had the Chareidim been giving 75 years of friendship and chizuk instead of 75 years of criticism and enmity, maybe the secular would have had bitachon in that crucial time, and maybe they would have no longer been secular in the first place.
