"In the wake of Operation Cast Lead, a group of American university professors has for the first time launched a national campaign calling for an academic and cultural boycott of Israel." Of course, I fully support this effort but I did not sign the petition because it did not go far enough for me. I can't sign any petition or support any effort that would recognize Zionist usurpation of any inch of Palestine. As the great George Habash used to say, the goal is the liberation of every millimeter of Palestine. (thanks Mirvat)
