I would listen to the military and do whatever they say needs doing. That would be after reinstating the generals and other officers who seem to have been let go or encouraged to leave because they disagreed with the minimalist approach of doing just enough to say something was being done.
I would have to interview to find out more about that first, but once properly staffed, I would turn to the military experts, and trust their advice, having told them that what I really want is ISIS destroyed. I would not pretend that they are the JV team. I would not pretend that they are anything other than orthodox Muslims carrying on the current era’s jihad as the logical extension of the 1400 years of the same that lead up to the modern implementation.
