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