“One of the most publicized and worst incidents [in Iraq] occurred [on May 7, 2004] when American contractor Nick Berg was beheaded by [al Qaeda in Iraq leader Abu Musab] al-Zarqawi in retaliation for ‘the treatment of Iraqi prisoners.’ That awful execution, which was filmed and released on the Internet, validated the brutality of the enemy we were facing.”
