Ah, war is easy in a book...
Not when the book is written by the likes of Ralph Peters. The man is a retired Army Intelligence officer. He's got two books (of 48) on the Army War College reading list Put his name into the War College's search engine, and you get 90 hits, either articles he's written, or other's comments on those articles.
Now don't get me wrong, I like Rummy, and I like his style. But about some things, I think he's too much the former corporate executive, and not enough the former Navy aviator. (He retired from the Naval Reserve in '89 as a Captain). Of course I don't always agree with Peters either, especially his opinion of the Air Force and it's procurement system, I thought the Air Force system was not very good, until I got a look at those of the Army and Navy. Yuck. (Of course the comparison is not 100% fair, since my "look" at each came at different times in the last few decades.)
