Consent of the parties
UN peacekeeping operations are deployed with the consent of the main parties to the conflict. This requires a commitment by the parties to a political process. Their acceptance of a peacekeeping operation provides the UN with the necessary freedom of action, both political and physical, to carry out its mandated tasks.
In the absence of such consent, a peacekeeping operation risks becoming a party to the conflict; and being drawn towards enforcement action, and away from its fundamental role of keeping the peace.
The fact that the main parties have given their consent to the deployment of a United Nations peacekeeping operation does not necessarily imply or guarantee that there will also be consent at the local level, particularly if the main parties are internally divided or have weak command and control systems. Universality of consent becomes even less probable in volatile settings, characterized by the presence of armed groups not under the control of any of the parties, or by the presence of other spoilers.
