This is one of the worst examples of twisted slanderous "journalism". Of course it's FOX News, Daniel Pipes, Drudge Report, and in this case Breitbart TV, all teaming up to thrust this craziness forward. Someone has spent a lot of time and money to create this hodgepodge of scare-mongering and "terrorist" labeling, with the intention of throwing it out in the final days of the campaign. One can see the hands of the furthest right-wing elements of the Israeli lobby and the Jewish Zionist Republican Neocons in this.
As for Rashid Khalidi. If anything he's criticized by the Palestinians for being far too 'moderate' and working much too closely with the American establishment including the government sponsored Woodrow Wilson Center, the University of Chicago, and the Republican International Institute. If anything he represents the Westernized Palestinian upper class long accused by their own of being co-opted and far too close to the American and Israeli governments.
But then...so much for the facts. Twisted headlines provoking more irrational and simplistic slogans and fears of "terrorism" everywhere are the order of the day in many American circles...and not just those associated with John McCain and the Christian Zionist Evanglicals he's now in bed with.
