Mr. Perle talked about the book he co-authored with David Frum, An End to Evil: How to Win the War on Terror, published by Random House. Mr. Perle said the book provides a blueprint for winning the efforts to combat terrorism. The recommendations were divided into four major sections: what must be done domestically to improve safety and security; what must be done abroad, in order to take the war to America's enemies; what must change in the realm of thought and ideas; and how U.S. institutions must be reformed to meet and overcome the new threat. He advocated an activist approach be taken by American citizens and suggested that the U.S. sever ties with Saudi Arabia, disregard much of Europe as allies, and overthrow the government of Iran.
