Gregory D Johnsen

Reporter Gregory Johnsen talks with Fresh Air's Dave Davies about the humanitarian crisis in Yemen and how the chaos is impacting the U.S. fight against al-Qaida. Johnsen describes a country torn apart.

In his new book, journalist Gregory Johnsen charts the rise of Yemen as a haven for al-Qaida and explores the recent history of radical Islam in the Arabian Peninsula. The death of Osama bin Laden, he says, had more of an effect on the U.S. psyche than it did on people in Yemen.
