soldier 2: hmm?
soldier 1: i mean... what's the point it can't be for the land because everything is burned, bombed or polluted. it can't be for the money because there is anything left to spend it on. so what is it? religion? why do we fight?
soldier 2: to win the war.
soldier 1: meh... works for me.
