i find that statement true. moreover, war exists because of differences and greed in human. there is always insecurity among us even in our daily life. on a small scale, even sibling rivalry which cause negative result either jealousy, insecurity, spitefulness and others.

however, i dont think that we can solve this inferior complex desire of US HUMAN as it is built into us by our creator. maybe there will be a weapon SO POWERFUL, it removes the urge to be better than other people. then, maybe we will stop pointing weapon at each others.

with great power comes great responsibility, however human heart is insatiable
