Join the New America Foundation and The National Interest for a discussion with Matthew Alexander, the former senior military interrogator who led an elite interrogation team in Iraq that found Abu Musab al-Zarqawi, the former al-Qaeda leader, who was killed in a subsequent air strike. Alexander has just authored a cover story for The National Interest on the relationship between interrogation techniques and deradicalization in Indonesia, and has conducted more than three hundred interrogations and supervised more than one thousand.
