Yes, I would definitely agree with that. Certainly, as I mentioned in my comments, social media has become a force multiplier for these extremist groups.
I remember back in the mid-1990s when the war in Chechnya had kicked off and there were the first real Wahhabi-Salafi jihadist manifestations there. Beheading videos were available on CDs. Then in the early 2000s those video clips were uploaded onto the just-emerging social media and Internet. Then there were password-protected chat forums, and then just open public forums. Certainly social media has given things a very different spin.
Very quickly on the last question on commonalities in backgrounds, really the two most common things are ideology and grievances. Ideology without grievances doesn't resonate, and grievances without ideology are not acted upon. Those do tend to be common elements when we talk about this space.
Thank you.
