Not many Jews I know of think all of ancient Israeli is nescessary, for every american yutz who demands such a thing (seeing as his ass aint getting shot at) to the orthodox who think Israel shouldnt exist and would be happy to give it all to the arabs there is a lot of leeway. If it was possible and the situation was different, maybe. At this point in time accept what the arabs are slowly realizing, lebensroom is what you can hold right now.
thanx,
