Unfortunately, Michael Brenner's assessment of the situation seems accurate. My only quibble is with the implication in the article that if Obama was different things might go better.
It is also possible, that the US is just in an intractable position on this. US policy is driven by Christian and Jewish fundamentalist Zionist zealots, the military-industrial complex and AIPAC. These disparate forces have controlled US Israel policy for decades now and it hard to see how Obama, regardless of what skills and inclinations he has, could do anything about that.
The fact seems to be that the US is constrained to work against its self interest and against a peaceful, equitable solution to the Israeli/Palestinian conflict by its own internal politics and there is just nothing in the foreseeable future that is going to change that.
