Mike-- and others,

The Corr and Sloan book I mentioned in the previous post has a chapter by Cesar Seresres on Guatemala. He has written extensively on the Guatemalan insurgency. An academic at UC Irvine, he served at State in the 80s working for Luigi Einaudi. So any book or article by him is a good palce to start.
The Zimmerman chapter goes into a lot more detail than the small quote I included on AID/COIN in Thailand and clearly expands the assessment not just of that relationship but of the COIN as a whole.
CORDS is usually held up as the way to best integrate US civil - military operations. I have taken this approach my self many times. Your description, however, suggests a larger distance between institutions than I though had existed. So, how does one achieve the required unity of effort when institutional resistance to unity of command wins out?

Cheers

John
