Leo Strauss (wiki) and Sayyid Qutb (wiki)

This clip is from the Power of Nightmares (Full Doc) and this part of the Wiki description.

"In the 1950s Sayyid Qutb, an Egyptian civil servant turned revolutionary, and Leo Strauss, a Jewish-American professor of political philosophy who fled Nazi persecution, were both in America at the same time. Qutb came to see Western liberalism as corrosive to morality and to society. Qutb had been sent to the U.S. to learn about its public education system but was disgusted by what he saw of its society. They each argued that radical measures (in Strauss's case, deception along the lines of the Plato's Noble Lie, and in Qutb's case, the creation of an Islamic state) could be justified in an effort to restore shared moral values to society, and their arguments heavily influenced American neo-conservatism and radical Islamism, respectively."
