It is useful to think that there are some people still thinking about strategy, tactics and low level philosophy. I have always liked William Lind....here is his classic statements on strategy. In this article, he warns of "maximalist" strategy..that is to say..."all or nothing" strategy. Bill Lind uses America's War in Iraq to illustrate some of his points.
I like his last line....An administration that has made loyalty to the White House’s maximalist objectives its most important test is not likely to encourage consideration of alternative strategies. When it becomes clear that we will not attain those maximalist objectives, there could be a sudden, desperate quest for some way out that leaves a few of our tail feathers intact. At that point, the thoughtful work of a small group of Marines might find an audience.
