NOVA: On 11 September, 2001 a horror unfolded that devastated the United States and the world. Fifteen years later, people are still gripped by terror as attacks have been mounted around the world, but the attackers are no longer commanded by a central entity. This report traces the evolution of terror strategies, from 9/11 to today, to find out how radical organisations have grown to make use of modern propaganda and social media tools in order to cultivate an army of self-radicalised killers.
