Religion plays a heavy rule in this region. Especially in politics, sadly it has negative outcomes though.

Instead of religion putting an end to the conflicts, it just motivates these people to start more violence and therefore these nations won't be able to prosper that well. And not to mention the amount of damage done to the people who live in those areas, those that die have lost their lives, and those that do survive, live in fear and don't get to enjoy life.
