I've always been a fan of books that create an interesting blend of fact and fiction - whether it's Norman Mailer, or 'The Short Timers,' or 'In Cold Blood.' I'm a fan of that genre.
One big, glaring difference I can think of between Iraq and Vietnam is the news coverage. During the Vietnam War era, you had TV coverage of the war saturating the airwaves every night, and that coverage wasn't put through a military filter at all.
I actually think every war movie is an antiwar movie in its own way - with the exception of some of the propaganda movies.
