As seen from the perspective of an American Jew, I am puzzled why Israel does not insist on recognition and an acknowledged right to exist as a precondition for talks. When the Palestinians talk about 1967 borders they mean all of the West Bank and E. Jerusalem. I seriously doubt Israel will make concessions on E. Jerusalem so I am not hopeful at all that anything will come of these discussions. The real issue for Israel and the World is to halt Iran's development of a nuclear bomb and I suspect it is only that concern that drives Israel to go along with Obama's insistence on 'useless' peace talks. It would be interesting to understand why Obama 'needs' the peace talk charade to go forward. He has not made clear, although one can guess, what is America's strategic interest in the Middle East and why he is cozying up to Arab states.
