Isis - Inside the Army of Terror

In ISIS: Inside the Army of Terror, American journalist Michael Weiss and Syrian analyst Hassan Hassan explain how these violent extremists evolved from a nearly defeated Iraqi insurgent group into a jihadi army of international volunteers who behead Western hostages in slickly produced videos and have conquered territory equal to the size of Great Britain. Beginning with the early days of Abu Musab al-Zarqawi, the founder of ISIS's first incarnation as 'al-Qaeda in Iraq,' Weiss and Hassan explain the key players and their origins, and how the movement has gained support.
