Can Tunisia Change the Arab World?

After weeks of massive protests, Tunisia's dictatorial President Zine El Abidine Ben Ali fled the country on Friday. Yesterday, his Prime Minister formed a unity-government, but today four members of the opposition resigned and clashes continued between police and protesters on the streets of Tunis, after a revolution unprecedented in the modern Arab world. Nobody knows if the ousted President Ben Ali will be replaced by democracy, a military coup d'etat or chaos. Whatever the outcome, many Arabs are thrilled for the moment by a popular revolt against repression, corruption and abuses of power. We update events in Tunisia, look at the possible repercussions throughout the Middle East and the consequences for American foreign policy.
