I have previously posted on the military’s need to enter the 21st century and the Age of 4th generation warfare. A negative milestone was reached when John Nagl retired, still a LT colonel in spite of being the expert in COIN warfare. Now, we come upon a comment from a student at the Army’s Command and General Staff College who writes that the lessons of Iraq and the theory of COIN war learned at so high a cost in Iraq, are not being taught. The Big Army, a term used by Robert Kaplan in his book “Imperial Grunts,” seems to be immune to the lessons of Iraq. Maybe it’s not as bad as that, if you read all the comments. Still, it is a worry.
