I doubt even you would have ratified or supported any Olmert offer in 2008. Part of any negotiation is judging the ability of your opposite number being able to deliver. By early 2008, the writing for Olmert was on the wall and he'd been judged wanting by the Israeli public. And Livni was already challenging him for Kadima party leadership. The Knesset would never have ratified the offer had Abbas said "yes" and you know it. Shas would have walked as they threatened multiple times during 2007 and 2008 any time any hint was made of nearing an agreement. And if Shas walked, the coalition would have collapsed.
