Turning the Tide: Iraq and Vietnam - Noam Chomsky:
"Personally, I don't see much useful analogy between Iraq and Vietnam. Vietnam was in a remote corner of the world that no one cared about very much, so the US could pound away at it, devastating four countries, with little international protest, and that little mostly about the bombing of the regions in the northern part of north Vietnam, where bombing might have costly repercussions. And even that protest, in the US too, was long delayed. Iraq, in contrast, is at the heart of the world's major energy reserves, which is why the US invaded in the first place. So anything that happens is likely to have major effects."
