I realize that super, but the majority of the American and Western populace doesn't quite understand or care about economic and political reasons, that's why Bush had to blather on about WMD's for this Gulf War. Being able to justify your war to voters is very important. And PR came into that quite heavily. PR also played a huge part in the media during that war, they allowed CNN to have these fancy shots of bombs taking off, instead of allowing them to see the actual results of the war (bodies and such). PR was very important during that war and every war since WWII.
