::I don't know if this is worth including in Jihadi John but it is very clear at this point that ISIL does a very good job as far as making viral videos is concerned and its social media arm is very strong. Aside from their execution videos, even their propaganda films are extremely well edited and produced. I think this is something that is addressed at the main ISIL article at Islamic State of Iraq and the Levant#Propaganda and social media. So, in my opinion, most readers would be able to relate that to the quotes in question. Maybe a wikilink to that page if editors still feel its not clear enough? -
