Futile efforts of Obama-Kerry are made in the most inappropriate time. Inapropriate for the US which is financially bankrupt with nothing substantial to offer to either side. Neither Israel nor the Palestinians trust this administration based on the previous five years. The US Congress isn't endorsing any new initiatives either with President Obama facing a Trifacta of scandals. The present Israeli leadership can only give the Palestinians much less than promised by Ehud Barak and Ehud Olmert. Abbas has little incentive to engage in anything serious without elections and without Gaza. The whole Middle East is in an incredible turmoil that would prevent any, any, Israeli leader to make serious concessions.
