"The political outcome of Hamas' raid on Israelis at Kerem Shalom on Sunday is that Prime Minister Ehud Olmert's convergence plan is being set aside for now.
Three elements have foiled Olmert's scheme. First, the government and the Israel Defense Forces failed to formulate a convincing security response to the continued attacks against Israel from the Gaza Strip. Under such conditions it is impossible to convince the public that there is logic in a pullout from the West Bank, which will bring the Hamas militants closer to Israel's population centers.
Recent surveys have showed broad public opposition to the convergence. The demographic threat at the root of the plan sounds frightening, but it is still distant and not palpable. The Qassams and the Hamas are nearby and obvious to everyone.
A massive ground offensive, with which the government threatened the Palestinian Authority on Sunday, will only justify the claims of Benjamin Netanyahu and the right that Israel is unable to defend itself against Palestinian terrorism from within its borders, and consequently the country must hold on to the territories."
