your logic is extremely flawed, to say the least, not even sure where to begin, but anyway... 1. It's not up to arabs to topple the govt of a sovereign nation...if Israel sees arabs are trying to interfere, the Israeli public will resist...there is a good chance that you'll see a far more right wing leader than Netanyahu. 2. Obama can't afford to alienate Israel, he is so low in the polls and repubs are using this issue to shore up support. 3. arabs have had plenty of Israeli govts to work with from the very liberal to the more conservative and they have failed to make peace with every one of them so it's hardly Israel's fault that there is no peace. 4. If labor backs out, they can be replaced with a series of far right wing smaller parties. 5. abbas can't deliver peace and everyone knows it, including abbas, so this is little more than a charade that will bring no substance...until abbas finds a way to bring hamas in and get them to accept Israel's right to exist as a Jewish state, there will be no real progress. And that's just for starters....
