Yes, then Israelis and Palestiians appear to be finally making some progress. But it is hard to be optimistic. Beyond the Cusp (a fantastic blog/blogger) takes a cold, hard look at reality. What happens if Annapolis does succeed? He goes on to make 3 main points:
1. Implementation of the agreement would be extremely difficult
2. Once Israel withdraws from the Palestinian territories (which will be certainly part of the agreement), Hamas will take power from Fatah and declare any agreement invalid.
3. If the agreement appears unsuccessful, Iran and/or Syria could take advantage of the situation and could possibly invade Israel, leading to a regional war.
Hits the nail on the head.
