The PLO is the *only* Palestinian organization that has the authority to sign a final status treaty with "the Government of Israel" e.g. Bibi can not sign any treaty as "leader of Likud", he can only sign as "PM of Israel". Abbas can not sign any treaty as "leader of Fatah", but he can as "Chairman of the PLO". Hamas are as much out of the picture as Kadima is. Are you really that clueless, SDHD?
