You start with an ideological movement that believes in grabbing more land when the moment is opportune for doing so. You then claim the land is empty except for squatters, usurpers who are here because you are here. Then you claim that that non-people of course has no one to talk to since they are a non-people out to destroy you who are a real people, the only real people of the land. Everything else follows. Gaza was a ruse for solidifying the annexation of blocs of demographically secured land masses that will affect the formation of a truncated Palestinian state. Gaza was a loosing proposition from the start in terms of treasure and manpower. Lost cause given up to expand what looks like a sure thing. Mix in a huge dose of unilateralism, military machismo to teach the non-people a lesson of how to behave, then wall them off into their bantustans and everyone will be happy except for the non-people who have no one you can talk to on the other sideand they'll just have to cope.
