I think it is a significant factor, sir.
I think one of the problems that we're facing now is that young people, especially young men, are always idealistic and can be swayed by the romance of a great cause, whether it was the beginning of the 20th century when anarchism or some other cause had young people involved in terrorist activity. We see the same thing now.
You mentioned that you, and certainly we remember 9/11, but 9/11 is now 16 years ago, and the reality is that there are young men who don't remember 9/11. They've seen it maybe on television, but it wasn't something that happened to them. It's their ability to see what's going on against the Islamic State now, to be touched by cyber-conveyed propaganda on the Internet that says, “Oh, this is the world beating up on good Muslims,” to get caught up in that cause and then, foolishly, but understandably decide they're going to either go overseas to express their frustration by joining the fight, or do an attack in the United States because we are pressing the fight against the Islamic State, or in Canada because you are. They turn their frustration on us. They don't remember how 9/11 changed things.
I think we have to be very concerned, and there's great room for co-operation now.
