Your idea sounds good at first however after thinking about it i was a bit bothered. I'm definitely a leftist and i'm very in support of the disengagement from Gush Katif however what you suggest IS betrayal. Abandoning them like that is too much. Its better, in my opinion, to force the settlers into doing what is best for them and for the nation.
