Most important, the PA has accepted it's role as the representative of the palestinian people.
They had an election, monitored by Jimmy Carter, and Yasser Arafat was elected President. Jimmy took a pass on his reelection, it was canceled.
And through it all, they've stayed true to their objective, the desturction of Israel. They've faithfully cashed every check sent by the EU, the US and Israel.
They've gratefully accepted arms for their police force provided by the US and Israel (Egypt surreptitiously), as well as training in how to use them.
Arafat's delegations have never stolen towels from the White House, they're not Clintons on an aircraft carrier.
