Recently Professor Hansen published a piece titled "Radical Islamism and Totalitarian Ideology: a Comparison of Sayyid Qutb's Islamism with Marxism and National Socialism" in the journal Totalitarian Movements and Political Religions. If you are interested, the article is online; you can find it here.
He's also been asked by that same journal to join their editorial board; congratulations, Professor Hansen, for that honor!
