United Nations

The United Nations is an international organisation, founded in 1945 in the aftermath of the Second World War as the successor to the League of Nations. The aims of the organisation are to maintain international peace and to promote cooperation in solving international economic, social and humanitarian problems.

The United Nations has appeared in the Deus Ex series mostly through the actions of the United Nations Anti-Terrorist Coalition and the World Health Organisation (WHO).

UNATCO
UNATCO was founded shortly after the events of Deus Ex: Human Revolution in response to the the growing problem of international terrorism. The organisation's headquarters are on Liberty Island in New York.

In the world of Deus Ex, it is generally understood that the organisation is controlled by the Illuminati and later, Majestic 12.

World Health Organization
In Deus Ex: Human Revolution, the WHO was involved in the recall of the biochip which led to the catastrophe at Panchaea.
