Yes, the only thing I would add to that is to emphasize the point Monik has made.
It's a very personal thing, the radicalization. What radicalizes one will not necessarily radicalize others. In some cases it's a personal connection to an individual, and in other cases it may be peer pressure. But what we've seen is that the trend is certainly increasing.
As I indicated with one of your earlier questions, I believe, there's the role of the Internet, the ability to recruit over the Internet and make jihad in some cases appear romantic, for lack of a better term. I'm sure many of these young Canadians are arriving and are completely taken aback by the reality of the situation they now find themselves in.
I would suggest that the Internet has been a principal driver, but as Monik has suggested, there's not one mould that will fit the radicalization process for everyone.
