Howdy Gabe1; My God man, historic Eretz Israel (as under King David circa 1000 B.C.) would include Lebanon up to the Litani River, most of southern Syria all the way to Iraq, about half of Jordan, and most of the Sinai. I don't think that it's realistic today to restore the boundaries of the Kingdom of Israel. I would go with Israel up to the security barriers (including the Golan Heights) as being reasonable. Israel cannot ethnically cleanse 4 million Palestinians from the Territories and she cannot accept them as citizens (nor the 4 million diaspora Palestinian refugees either). It's best for each side to settle for what they can get now, but there is no one to talk to on the other side (as you pointed out) since the Palestinians are nothing but a chaotic pack of squabbling clans with no sense of national identity whatsoever.
