The UN has also drawn criticism for perceived failures . In many cases , member states have shown reluctance to achieve or enforce Security Council resolutions . Disagreements in the Security Council about military action and intervention are seen as having failed to prevent the Bangladesh genocide in 1971 , the Cambodian genocide in the 1970s , and the Rwandan genocide in 1994 . Similarly , UN inaction is blamed for failing to either prevent the Srebrenica massacre in 1995 or complete the peacekeeping operations in 1992 – 93 during the Somali Civil War . UN peacekeepers have also been accused of child rape , soliciting prostitutes , and sexual abuse during various peacekeeping missions in the Democratic Republic of the Congo , Haiti , Liberia , Sudan and what is now South Sudan , Burundi , and Ivory Coast . Scientists cited UN peacekeepers from Nepal as the likely source of the 2010 – 13 Haiti cholera outbreak , which killed more than 8,000 Haitians following the 2010 Haiti earthquake
