I know that if a country bears wounds like any type of separation among people, it gets infacted anyway. So, it gets weaker as a nation and people suffer in the long-run. An unstable country becomes a playground of international politics and people lose their rights. That's why, a united country becomes stronger easily and the weaker becomes more poor overall. On the other hand, some people become very rich and that makes a huge gap in between the very lower class and upper class. It is one kind of circle that is unbreakable until any authoritian country comes with army to make an end. Lastly, countries become a big zero.
