There's more here than meets the eye...or the ear. Dershowitz is on a roll clearly coordinating with Ariel Sharon personally.
It's all in anticipation of a big p.r. push next year to corner the Palestinians into living with, if not agreeing to, a fractured apartheid-structured quasi-non State 'Palestinian State'. Chomsky, though expressing the same harsh and realistic views he has for years, grafted on top of so much fact and history, is himself manuevered into the position of supporting the 'Geneva' approach which itself comes out of the old Olso-era and is coordinated by Yossi Beilin representing the so-called left Israeli establishment and the despised (by his own that is) Yasser Abed Rabbo represented the discredited and sinking 'Palestinian Authority.' So this debate doesn't take place in an intellectual vacuum. It is being so widely distributed precisely because it is being used for important political purposes; and in that context at the least Dershowitz is the big winner.
