Book review: �Invisible Armies,� a history of guerrilla warfare, by Max Boot

I first encountered the concept of guerrilla warfare back in 1964. Friends of my parents had dropped over for coffee. Pleasant banter quickly turned ugly when the subject of Vietnam arose.

No one seemed to understand why such a small problem was vexing mighty America. Someone questioned why the United States needed to fight that war. Someone else mentioned that the Vietnamese were guerrillas and no one could find them. One particularly belligerent neighbor � a fan of Barry Goldwater � argued at maximum volume that the solution was surely the atomic bomb.
