It appears that political correctness has infected many of our military brass, indeed even instructors in our military academies. It is one thing when politicians and cultural elites force it into our lives; it's quite dangerous, however, when those selected to protect us elevate political correctness over the necessity of vanquishing enemies intent on destroying us.
The author has an uncanny ability to completely miss the point. This is a counterinsurgency manual, not an all-encompassing manual on warfighting doctrine. The military's job is to execute within the limitations placed upon it by the civilian leadership. In the case of counterinsurgency, the manual states doctrine that is developing based upon lessons learned from fighting against insurgencies within those likely limitations. If the author has a problem with that then his beef should be with the civilian leadership, not the military. Just because the military lays out doctrine for how to fight certain kinds of wars in a certain way, that does not mean that the military prefers all wars to be executed in that manner or believes in the prudence of the limitations placed upon it by the civilian leadership.
