History in the Making on the Streets of Egypt

In Egypt tonight, tens of thousands of protesters defied both tear gas and an official curfew imposed in Alexandria, Suez, Cairo and other parts of the country. In Cairo and Alexandria, the Army was deployed and embraced by demonstrators after brutal violence by the riot police. The government has shut down most lines of communication with the rest of the world. Well into the evening, President Hosni Mubarak, the Army's Commander in Chief, had yet to be heard from. There were reports that his family had left the country. Can his 30-year-old administration survive tonight's unprecedented uprising? What about the rest of the Middle East? What does the Obama Administration have to say?
