Olmert's proposal went further than Barak's 9 years ago regarding RoR...
http://www.jpost.com/servlet/Satellite?cid=1243346501041&pagename=JPost%2FJPArticle%2FShowFullAbbas also told The Washington Post that former prime minister Ehud Olmert accepted the principle of a "right of return" to Israel for Palestinian refugees and offered to resettle thousands of Palestinians in Israel. And he said Olmert proposed a Palestinian state on 97 percent of the West Bank, and showed him its contours on a map. Abbas said he turned down Olmert's peace offer because "the gaps were too wide."
....
What's interesting about Abbas's hardline position," wrote The Washington Post's Jackson Diehl, who conducted the interview along with a colleague, "is what it says about the message that Obama's first Middle East steps have sent to Palestinians and Arab governments... in the Obama administration, so far, it's easy being Palestinian."... Obama, with his repeated demands for a settlement freeze, "has revived a long-dormant Palestinian fantasy: that the United States will simply force Israel to make critical concessions, whether or not its democratic government agrees, while Arabs passively watch and applaud."
So Abbas is pissed off...but not really too much because things aren't that bad for Palestinians after all:
"Until then, in the West Bank we have a good reality . . . the people are living a normal life.” — Mahmoud Abbas
So he's pissed that he's not getting all he wants but he can live with it for now because things are pretty normal.
It's hard to imagine Netanyahu offering anything similar to Olmert's rejected offer from last year.
This isn't ending anytime soon.
