This mistaken idea comes largely from the strategic bombing folks of the first half of the 20th century, beginning with Douhet, who presumed that once air power became involved, war was too horrible to contemplate.
So, as the good Commander below reminds us, air power cannot defeat ISIS in Iraq. What needs to be added to this piece is another reminder about war that Clausewitz told us of in the early 19th century. "In war, the result is never final." (On War, Chapter 1, section 9)
