Israel doesn't have to make a single concession, ever. In fact, it can continue to take whatever it likes with impunity, and it does. Sitting down to peace talks would involve compromises, and Israel does not have to, and won't, make any compromises. Why should it? So there will be no peace talks and no Palestinian state. That is the last thing Israel wants, a sovereign state right next door full of the enemies it's managed to make down the decades. The reason for this parlous stalemate is the continuing unconditional bankrolling of Israel's military by the US. That will continue to be unconditional because the Israel lobby, led by AIPAC, does not permit any talk of making aid to Israel conditional on Israel's good behaviour. Actually, there is rarely, if ever, any real talk about what really goes in Israel at all in the US Congress. It is simply not tolerated by AIPAC et al. To go against that, to stir anything up, would be political suicide. To find out what is really happening to the Palestinians you have to dig much deeper than most Americans are willing to dig. Israel is a little tail leading a huge great big dog by the nose. Witness Obama's soft talk in Jerusalem today. He's going nowhere and neither are the Palestinian people.
