War tends to reinforce the conflict and incur larger damage.

People need to be well-educated (really learn a lot about how to think, not just good in memorization) enough to not be misled by some self-interested elites to exploit conflict for their own personal benefits. I know it is challenging to enlighten so many people in the world, but it is the only way. What we can do is first trying with the most potential people – the elites that still care about others.
