I’VE BEEN READING JIM DUNNIGAN’S NEW BOOK, The Perfect Soldier: Special Operations, Commandos, and the Future of U.S. Warfare, and I think it’s pretty good. There’s a lot of information on how things were done in Afghanistan. One thing that it makes clear is the importance of the learning curve — and, in particular, the importance of learning from things that don’t go well. That’s a lesson worth taking to heart in our ongoing war.

The book also has lots of useful background and reference material, which I imagine journalists and lawmakers will find helpful. And, like all Dunnigan’s stuff, it’s clearly written and highly readable.
