Vonnegut is a frustrating author to me. He has a sharp wit and he picks worthwhile targets to satirize. But his books are thin and scattershot. This one leaves me with the impression that he has not really thought through what Nazism was or the specific ways that the U.S. was morally compromised and ideologically conflicted during World War II and the years immediately before and after. It's hard to take Howard W. Campbell seriously as a character because he often seems to exist on the page mainly so that Vonnegut can just riff on his chosen themes.
