This week on Babel, Jon Alterman speaks with Prof. Killian Clarke of Georgetown's Edmund A. Walsh School of Foreign Service about his forthcoming book tentatively entitled The Return of Tyranny: How Counterrevolutions Emerge and Succeed. They talk about the counterrevolution in Egypt, the complex relationship between the military, the Muslim Brotherhood, and the public, and lessons learned from counterrevolutions around the world. Later, Jon continues the conversation with Natasha Hall and Lubna Yousef, debating similarities between Egypt and Tunisia, and how the region views U.S. influence post 2011.
