I wasn't offended by that book cover because it looked like a bunch of hippies fighting as to who would get the last bong hit and a flag got in the way.
Kerry's book cover and the picture above from pre-GWII are examples that American veterans serve and die so that these types can legally make royal @$$es of themselves and receive the accompanying publicity.
The fact that Kerry was a Viet Nam veteran (as he repeatedly reminded anyone who was within earshot) should make this point all that more ironic.
