Who Does Hamas Represent?

"There was an immediate reminder of the fragility of those declarations when spokesmen for the radical Palestinian group Hamas said the truce was not binding on them."

Of course this truce is not binding on a radical group of extremists. They merely have "spokesmen", no actual leader with whom to make a truce. Abbas has his work cut out for himself. At least he seems willing to make the attempt, Arafat only encouraged the militants.
