George Clooney is the most persuasive voice for the independence of South Sudan.

Last month he visited southern Sudan to draw attention to the dangers that the area could return to war over the issue of the independence of southern Sudan from the north.

Back in the U.S. Clooney gave his smart, sharp take on Sudan to President Barack Obama, the Council on Foreign Relations, not to mention Larry King and the Today show.

Monday night he continues his campaign by speaking to anti-genocide activists at Stanford University. Clooney co-wrote an article with John Prendergast of the Enough Project in which they argue that U.S. diplomacy can steer Sudan to a sustainable peace.
