I mean this to be separate from the running discussion of ISIS, focusing on a discussion of what our response should be after months of limited air strikes and arming small groups. We had a good discussion last year about what our military response should be. Most people, if I remember correctly, thought the President went in with too soft a touch. So months have passed and you're the CiC, and you run the military. Do you continue arming terrorists and crossing your fingers that they won't turn on you? Do you keep playing Drone Santa? Do you commit a number of ground troops? Do you stay out of it? And how has your opinion changed from that turning point when the Yazidis were trapped on the mountain last year, if at all?
