Just in time for the renewal of the war debate in Congress, the University of Chicago Press has released The U.S. Army / Marine Corps Counterinsurgency Field Manual. . . . It's a nifty volume, not only because it gives you a sense of what our most highly regarded military theorists are thinking but because sometimes what they're thinking is the last thing you'd expect. Especially interesting is a section called 'Paradoxes of Counterinsurgency Operations,' which tells us: 'Sometimes doing nothing is the best reaction' and 'Sometimes, the more force is used, the less effective it is.'
