The widely held presumption that splitting Jerusalem will lead to prosperity for the city and to peace for Jews and Arabs is an egregious error. Partitioning Jerusalem will destroy the city. It will die, in every way – culturally, religiously, economically and more. And it will turn into a Belfast-style battlefield.

The Lieberman laxative is a bitter pill, meant for die-hard, old-style peace processors, which flushes away the Annapolis process, the Arab League initiative, Oslo residue and more.

The newfangled “shelf agreement” concept, which served as the basis for the Olmert government’s negotiation with the Palestinians, was strategically illogical and tactically ill-considered. Israel must not again go this route.
