base for terrorist operations. specifically, this group isis. the group has taken over a third of iraq. more vicious than al qaeda. but one of the most impressive, for lack of a better term, qualities they have is in social media. they put together these very slick video productions. very, very good at using twitter in order to create a media narrative. and it's clear that in terms of the social media competition among terrorists, this group is winning. >> you've broken this out in three specific ways. let's go one by one. the first one is memes of terror. what does that mean? let's talk about that. >> it's your typical meme you might see making a joke on facebook or anywhere else, except this is often written in english. you have the example right there that someone involved with the intelligence community sent to me yesterday. if you look at the different messages there, first they're saying the iraqi government has no soul because it collaborates with the united states. secondly, they're saying, look, look at the american humvees that we're controlling.
