A Marine With a Clue

Thomas Hammes is a Marine Colonel who has written a book on insurgent warfare vs. superpowers. From Chapter 1:

"Fourth Generation Warfare is the only kind of war America has ever lost. And we have done so three times - in Vietnam, Lebanon, and Somalia. This form of warfare has also defeated the French in Vietnam and Algeria, and the USSR in Afghanistan...As the only Goliath left in the world, we should be worried that the world's Davids have found a sling and stone that work."

He was interviewed on NPR today and estimated it would take 10 years before we got out of Iraq. There is a good piece by him on recent operations in Iraq here.
