A study by the RAND Corporation in 2005 found the UN to be successful in two out of three peacekeeping efforts. It compared efforts at nation-building by the UN to those of the United States, and found that seven out of eight UN cases are at peace, as compared with four out of eight US cases at peace.
[115] 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 in that period.
[116] Situations in which the UN has not only acted to keep the peace but also intervened include the Korean War (1950–53) and the authorization of intervention in Iraq after the Gulf War (1990–91).

This also seems significant.
The
World Health Organization (WHO), which focuses on international health issues and disease eradication, is another of the UN's largest agencies. In 1980, the agency announced that the eradication of
smallpox had been completed. In subsequent decades, WHO largely eradicated
polio,
river blindness, and
leprosy.
[153] The
Joint United Nations Programme on HIV/AIDS (UNAIDS), begun in 1996, co-ordinates the organization's response to the AIDS epidemic.
[154] The
UN Population Fund, which also dedicates part of its resources to combating HIV, is the world's largest source of funding for
reproductive health and
family planning services.
