This poem is truly deep. It is interesting to see how war and advancement of the race seem to be so connected and how war can unify even the most diverse groups of people. My only suggestion is that the rhymes between "hands join into one -" and "proving: war's never any fun." was a bit forced. Other than that great write. 5/5.
