For me, motivation is a person who has the capability to recruit the resources he needs to achieve a goal.
Any non-commissioned officer is more of an enemy to a recruit, any schoolmaster to a pupil, then they are if they were free.
When I came to the CIA in the mid-'90s, our graduating class of case officers was unbelievably low. Now, after years of rebuilding, our training programs and putting our best efforts to recruit the most talented men and women, we are graduating more clandestine officers than at any time in the history of the Central Intelligence Agency.
Nobody, absolutely nobody, straps a bomb on their body because they were recruited from the Internet. It takes an enormous amount of personal face-to-face contact and time in order to recruit a young person into the cause of jihad.
I find a difference in British spy fiction and American spy fiction. In the American version, it's more militaristic, partly because the CIA has more of the military makeup. Whereas MI6 is more of a cerebral, intelligence-based, relationship-based service, i.e., all they do is recruit people to get information out of them.
