A civil war is more difficult to solve if all parties are not willing to set for talks and stop the violence. When the conflict is prolonged, each side is right, each side lost their people (supporters) and fighting for retribution and it’s not possible to convince them to forgive. So a distant intervention can be tricky especially when talking to all the involved parties is not possible and the conflicts are fueled by foreign interference to fuel the retribution cycle. Also, conflicts are caused on purpose to cause a sign of Judgement Day (increase of murder), draw the attention of the areas where the natural resources are getting stolen or to keep the country busy so its people can’t know or profit from their own natural resources. At the same time different conflicts in different parts are a distraction from the main ones.
