I'm the person who started this thread, and I am very surprised at the hostile reaction to Lembcke and his thesis. I feel inclined to defend him (although I, too, haven't read the book), but he can probably do a better job himself. Here is an article written by Jerry Lembcke himself on the same topic.

I have searched the web for reviews, but they are pretty scarce:

Here is a review that appeared in the Denver Post.

Here is a "thumbs up" review that appeared in "Storm Warning!" the publication of an organization called "Vietnam Veterans Against the War Anti-Imperialist." It also includes some enlightening quotes.
