"Internationally, the rule of the game is laid by everybody together," he said.

But at the democracy rising conference at UC Berkeley Friday afternoon Egyptian expert Shibley Telhami says the anger at least in Cairo is less about a movie and more about other issues.
"Because of the Iraq War and the war in Lebanon and the war in Gaza, blaming the U.S. for support of Israel there is very pervasive anger toward the U.S. and it comes out anytime there is an episode of anger even before they know the facts," Telhami said.
Telhami says the grassroots uprising of the Arab Spring facilitated by social media has contributed to the spread of demonstrations and even violence.
"There isn't a Mandela figure that people can look up to and say Mandela says this is wrong," Telhami said. "There are a lot of people who say it's wrong we have an elected president in Egypt, Morsi, who's been saying it's wrong but how many people will listen to him."
Telhami says not many.
