Nothing we shouldn't have learned from Vietnam, IMO. Or any number of other places. Sadly, I have great faith in the institution's ability to learn exactly nothing lasting from all this (except perhaps the desire to plan for fantasy war).

Sorry if that sounds cynical, but just about everything listed here could have been gleaned from a good review of stuff that came out during and immediately after Vietnam. Or a close reading of the original Small Wars Manual.

As for using nukes...there are other consequences far beyond just the desire to use the big one. I don't consider that a viable option in situations like this...no matter how much Lind may think they're useful.
