<P> A 2005 RAND Corporation study found the UN to be successful in two out of three peacekeeping efforts . It compared UN nation - building efforts to those of the United States, and found that seven out of eight UN cases are at peace, as opposed to four out of eight US cases at peace . Also in 2005, the Human Security Report documented a decline in the number of wars, genocides and human rights abuses since the end of the Cold War, and presented evidence, albeit circumstantial, that international activism--mostly spearheaded by the UN--has been the main cause of the decline in armed conflict since the end of the Cold War . </P> <P> The UN has also drawn criticism for perceived failures . In some cases, the Security Council has failed to pass resolutions or the member states have been reluctant to fully enforce them in the face of deteriorating conditions . Disagreements in the Security Council are seen as having failed to prevent the 1994 Rwandan Genocide . UN and international inaction has also been cited for failing to intervene and provide sufficient humanitarian aid during the Second Congo War, the failure of UN peacekeepers to prevent the 1995 Srebrenica massacre, failure to provide effective humanitarian aid in Somalia, failing to implement provisions of Security Council resolutions related to the Israeli--Palestinian conflict, Kashmir dispute and continuing failure to prevent genocide or provide assistance in Darfur . </P> <P> One suggestion to address the problem of delays such as the one in Rwanda, is a rapid reaction force: a standing group, administered by the UN and deployed by the Security Council that receives its troops and support from current Security Council members and is ready for quick deployment in the event of future genocides . </P> <P> UN peacekeepers have also been accused of sexual abuse including child rape, gang rape, and soliciting prostitutes during peacekeeping missions in the Congo, Haiti, Liberia, Sudan, Burundi, and Côte d'Ivoire . </P>
