These borders go together with land SWAPS. The idea was accepted by practically all Israeli security experts that looked into it. Amnon Shahak-Lipkin ia a former IDF Chief of Staff and highly respected today, negotiated with the Palestinians the security part of the Geneva Plan (with Beilin). Geneva is based on 1:1 swaps. We need not go further than Netanyahu's partner today, Ehud Barak, who accepted the Clinton paramenters, involving a swap of 5-6% of the West Bank (plus 2-3% to remain in Israel, but these could also be swapped). Once you consider swapping areas, and most are swapped in order not to move too many settlers just because of the cost involved, there is no significant security issue. Netanyahu is trying to pull the wool over those fools who want the wool pulled over their heads.
