War or Peace?

Humans are humans, and humans are aggressive and violent beings. Disarmament only means that they will rebuild their military in secrecy. The Germans did it in the 40's, why couldn't any country do the same in today's world? Rather than pointlessly protest it or be mad at it, I just see it as an exciting/interesting news story. We can't do anything about war, unless we completely annihilate human individuality and thoughts/opinions. Another words, if all humans agreed and thought the same way, which will never happen.
