Was WikiLeaks to Blame for the Upheaval in the Mid-East?

In a lecture on the current state of affairs in the Middle East David Sanger the NY Times Chief Washington Correspondent, made a claim, that one of the reasons for the chaos which began in Tunisia, was started because of information about the lifestyles of the leaders which was leaked on WikiLeaks, and it was the embarrassment of the entire world knowing this which led to the revolution.  Is it really possible that WikiLeaks was actually able to on a somewhat direct level cause so much change?  We will see, as time goes on what, if any, other significant events unfold in response to the information exposed by WikiLeaks.
