Over the decades I've often quoted the analyses and judgments of Franklin "Chuck" Spinney. In the late 1970s and early 1980s he was part of an influential group of defense analysts (along with John Boyd, Pierre Sprey, Tom Amlie, Tom Christie, and others) whose work I described in National Defense. That is him, on the cover of Time magazine 30 years ago, at the right.
Then during the 2008 campaign he made a number of calls and projections that seem obviously true in retrospect but were at odds with "savvy" political wisdom at the time. You can see samples here, here, and here.
Spinney is back on the geo-strategic beat, with a dispatch arguing that the situation in Afghanistan is turning into an all-fronts disaster for the United States, and that the only positive outcome would involve (a) recognizing that fact, and (b) looking honestly at the sources of failure so as to reduce chances of their repetition. He is experienced enough to know that it often is impossible to draw honest lessons from failure, or even to admit or recognize it. But just after an election, at a time when the Afghan issue is less politicized than it has been (and perhaps should be), and when a new secretary of defense is about to take charge, is a good time to try.
