Impossible task for UN in DR Congo

The UN peacekeeping force in the Democratic Republic of Congo is the largest, most expensive and powerful in the world. Yet it still has been unable to prevent civilians from being killing in the conflict. The force was sent under the UN's most powerful piece of legislation - Chapter Seven. This gave the peace keepers the right to use and means necessary to impose their will. This tactic should have proved effective as it gives them the right to use lethal force in any situation. An additional 3,000 troops have been sent to Congo after an urgent appeal for troops made by the civilian head of the missions on the ground, Alan Doss. Since then thousands of people have been displaced from their homes and many have been slaughtered. Both sides of the conflict, the rebels and the government troops have been accused by the United Nations of committing war crimes. The UN force in Congo is made of soldiers from 18 different countries, India being the largest contributor. Yet with about 16,500 troops in the Congo the UN force is still outnumbered by 1000 to 1 by the civilian population needing protection. The former commander officer of the UN forces in the Congo resigned after stating that he believe that the mission in the Congo was "doom to fail". However, despite the great challenges facing the troops in the Congo they have managed to secure the capital Goma which is definitely a main target of the rebel forces. 

It is relieving to know that there are efforts being made by the UN that they have not done before. I think it was a good idea to allow the soldiers the right to use lethal force if necessary to impose their will. I also think that one of the great successes of this mission was securing the capital Goma. The UN is really making an effort this time by stationing the largest force it has there. Yet there are still atrocities being committed on both sides of the war. Both the government and the rebels are committing war crimes and this should be taken very seriously by the international community. Since the government is committing these crimes the UN should forcefully change the leadership in the government because obviously they are no better than the rebels themselves. People are being murdered and raped by both the rebel and government troops. I can understand why the commanding officer of the UN resigned because the force that the UN is against is a massive array of rebel forces who are driven by ethnic hatred and the desire to control the countries mineral wealth. What I cannot understand is the intensity of the ethnic hatred shown by these people. I do not know what can make a human hate another so much that he would be happy to slaughter his family as well as anyone associated with him.
