The "Looming Tower" interview
Austin Bay and I interviewed Lawrence Wright, author of the Looming Towers, a book which describes the origins of al-Qaeda and radical Islamism. Wright made the point during the interview that after Zawahiri and the other Islamists had been driven underground by severe repression from Arab governments they hit upon attacking America as a "softer target". That was a way of advancing an their agenda by the indirect expanding the definition of their struggle. You may want to listen to the whole podcast at Pajamas Media.
