I think we fought Vietnam for the benefits of civilization, and certainly we fought it to oppose authority. To show our authority, to show we weren't weak. Isn't that what Nixon kept saying? "We have to show the world that we're not weak." So of course what we ended up showing the world was that we were, yep, weak. 'Cause we couldn't beat these kids in black pajamas.
