There was a guy on "Book TV" a few month back who wrote a book describing how the difference between the AK-47 and the M-16 was the reason the US lost the Vietnam war.
                  That wouldn't be hard to do, though. The guy could just go through historical documents and pick out the ones that supported his proposition, and ignore the ones that did not.
                  You could make a case for going to war in Iraq that very same way.
