Human Nature.
People cannot help anger and hateing each other, they find excuses to start a row over nothing. on a domestic scale this can become bad enough, but on larger global scale it will lead to war and conflicts. A third party can help to resolve any situation, but then the hardness of our stubborness sets in to block off the mediation.
Wars are caused by the inherent Sin and selfishness of the human heart a condition that does not even leave those who have faith in God. But to have faith in God and a personal relationship does help us to see our own faults and ask the lord to help us, intead of ignoring or denying in the first place.
