Mitchell hasn't said anything on the record. Nobody in the Obama administration has said anything. The idea that this administration has been showing bias in Israels favor is rediculous If there has been any bias its been in favor of the palestinians, Obama may not have been able to deliver on all the things he led Abbas to think he could have but the US has been supporting the arabs over Israel. As we have no credible sources to back up this claim knowing the PA and their history its most likely to be all talk to gain sympathy and condemn anybody who doesn't back every single one of their demands. As for the idea of a binational state thats just the arabs living in fantasyland, Israels jewish majority will never allow and its an idea that no western politician would even have the courage to propose because it could mean the end of the career which is why they only ever talk about 2 states its the only thing they can propose without risking their jobs. So nothing to worry about.
