I believe that all wars have the same impact. The actual on-the-ground fighting leads to nothing more than a field of dead children and scarred veterens. To say that a war is great is usually to admit that it has resulted in the massacre of an entire generation. This is no doubt true of all wars as far back as when Cavemen A clubbed Cavemen B to take their fire.
I do not see any real difference between any of the wars fought by humans. They are all waged out of fear. Wars are not won on the battlefield and it is the social trends and support structures which influence world events and global relations.
