I believe that war is a instrument of economical gain (=power), used to effect financial agenda when all other avenues have been exhausted or proven ineffective. In that respect, yes, you are right, there is no winner because the people who go to war is always dying. However, once that agenda has been accepted by the people, and the engagement begins, there can be a winner and a loser... Or, if you prefer, a big loser and a small loser, as percieved and explained to you by the media.
