Another War soon gets begun, A dirtier, a more glorious one; Then, boys, you'll have to play, all in; It's the cruellest team will win. So hold your nose against the stink And never stop too long to think. Wars don't change except in name; The next one must go just the same, And new foul tricks unguessed before Will win and justify this War.
