The article I linked isn't the propaganda, there are other sources out there exaggerating the number, CNN is probably providing a more accurate story.
I'm not sure where he is getting the 200 from the single airstrike number. Usually the homegrown variety of terrorist though start by obsessing over the deaths of people in the middle east, then they start watching ISIS videos, they recite the quran, and shoot up an airport. He's been railing on that specific airstrike for a while though, enough that it can be considered an unhealthy fixation which is why I cautioned him about radicalization.
edit: here is another article.
