Does Terrorism respond to intervention?

I just watched Nova's "15 Years of Terror: From 9/11 to today’s crowd-sourced violence, trace how terrorists’ strategies have evolved".

I am interested in where it left off. That we are not going to be able to eliminate radicalized Islam through killing. We must offer those who are radicalized and who are likely to be a new hope a new understanding of their own religion in a peaceful view.

I was moved by the story of Mubin Shaikh. Starting at 44:30 Nova tells his story. He went to Syria to study the Quran. He met an Imam that decided to show him the peaceful teachings of Islam. Mubin Shaikh soon saw the Quran in a whole new light.

Mubin gives the example of chapter 9 verse 5 where it says "kill the unbeliever wherever you find them". The Imam asked him, do you normally start with verse five or do you start with verse one? Let's start with verse one. Then you get the context. This chapter is about the treaty the Muslims had with the pagans at that time. In verse four, it says this does not apply to the polytheists who did not break the treaty.

He learned after two years that he had it all wrong. The Imam told him to go back and teach the people that this is not our way [terrorism].
