I don't know what you call Barak and Olmert offers, but you should call them nothing more than propaganda attention getters. At Camp David Barak offered 61% of occupied territories; strategic roads to be used only by Israelis; continued Israeli control of all borders; all Palestine external trade to go thru Israel; large settlement areas and East Jerusalem to be retained by Israel, including 250 sq kilometers adjacent to East Jerusalem. The offer was take it or leave it. Arafat left it. Olmert?s 2009 peace offer was not rejected by Abbas. In fact, Abbas said with that offer(93%of West Bank and Gaza) "we can have peace in 2 days." The Quartet agreed, and requested Israel make the offer binding. It never did.
