This so-called talk is just a show. Israel's participation was just a response to US's pressure and many people had anticipated this fruitless result. The Israelis just stall for time to build settlement. It happened in the Likud party in negotiations with the Palestinians in 1987 headed by Shamir who put up obstacles after obstacles in order to bring down the talk. Israel would continue to build settlement and holds occasional 'nominal' peace talks. Obama administration faces crises in upcoming elections and the next talk is no time soon.
