Abbas couldn't sign a peace treaty if he wanted to. He does not represent the Palestinian people. Neither does Hamas. And there, folks, is the problem. The Palestinians are avoiding negotiations because they know they can't do anything. There will be no peace without Gaza included. There can be no peace if Gaza is included. The Palestinians are a lame duck. Hamas refuses to accept the concept of peace with Israel, and Fatah can't negotiate peace without Gaza. They'll blame Israel of course. But the truth for them is a bitter pill to swallow - they are still not yet ready for statehood.
