how is war fair?

how is war fair? I don`t think war is fair because what do you get out of war. Dieing solders family`s being missed love ones a lot of money spent and just the united states being corrupted. If your in a war what point is it going to prove nothing really just respect from our country. We don`t get nothing out of it just if we kill 1,000 people and they kill 500 of our people does not mean we won just means we are fighting for death and respect. truly that is what i think on the war.
