When I read this as a teenager in the early '60's, the novel was a unique sci-fi work in that it presented a first-person, military terrorist on an alien world. Based on later experiences, it was incredibly well constructed and could have served as a textbook for training an underground. Perhaps it did!
Basically he gave the idea, of 1 man making a difference, through non-violent means. The concept of the Wasp, is to annoy the enemy to the point of distraction. Let them hurt themselves trying to swat the Wasp. It's like the concept of Aikido, to use the enemies own energies against itself. I find this to be the progenitor of where Harry Harrison got his idea for the Stainless Steel Rat. At least in my mind. I only wish there was a sequel to this amazing book, of which i still have a mostly torn copy of. That i will always cherish. GREAT BOOK! Must have for your own Sci-Fi Classics Collection.
I loved this book in its original (?) publication, back in the sixties. Mac Reynolds(?) published some stories in Astounding/Analog that appealed to me for many of the same reasons. In retrospect, I wonder if the "Unibomber" was reading any of these "one against the evil empire" stories.
