This is not the first time that some sort of behind the scenes peace deal fell apart for one reason or another. just yesterday I read of some deal with Syria to return the Golan but the Arab Spring hit. In the case of Abbas and Olmert it was the continual firing of rockets into Israel from Gaza that forced Cast Lead. Seems that uprisings on the Arab side of the equation put quick ends to peace talks. Who is to say they do not happen on purpose .....also from the arab side.
Bennett, Deri expected to resign from Knesset, remain in cabinet under new 'Norwegian Law’ (Haaretz)
from the article: Abbas: Palestinians, Israel were two months away from inking peace deal
