Airpower is the simple but wrong/naive answer to complex problems. It just doesn’t work as advertised by the airpower enthusiasts. If you will the ends, you will the means. So those who want to wade back into Iraq or jump into wherever to “degrade and ultimately destroy ISIL” should be honest and note that ground forces are likely to be necessary unless the local partners are stronger than I think they are. But Americans so want to believe in Santa Claus… I mean immaculate warfare.
