Why is disharmony sometimes not the main cause of War?

Answer 1

What are you getting at with all of these questions about the "main cause of war?"

Disharmony implies minor differences between people -- but usually not enough to cause killing.

Answer 2

We have to try and find the root principle of war which is the main cause for war. But before we get to root cause we have to do process of elimination of other factors that really arent the main cause of war. My root principle is going to be Fear in the end.

Answer 3

Thank you for clarifying your question.

I think you're right that fear is the root cause of war, especially when you understand that fear is the other side of the coin from anger. When we're fearful, we either hide or we fight.
