ISIS is not an opponent that will meet you out on a big field. They don&#x27;t care if its USA or Russia. What they would rather have is Russian and American troops invading. They&#x27;d love that. Film it all, post it up on twitter to convert a large swath of the population that is &#x27;on the fence&#x27; to join their death cult.  
A show of naked force is EXACTLY what they want, because it means they WIN.
