Page "Peacekeeping" Paragraph 5

Most such international operations are established and implemented by the United Nations itself, with troops serving under UN operational control.

In these cases, peacekeepers remain members of their respective armed forces, and do not constitute an independent " UN army ", as the UN does not have such a force.

In cases where direct UN involvement is not considered appropriate or feasible, the Council may consider authorizing regional organizations such as the North Atlantic Treaty Organization ( NATO ), the Economic Community of West African States, or other coalitions of willing countries to undertake peacekeeping or peace-enforcement tasks.
