Taken from UN Security Council Resolution 1723 (2006) which extends the UN Mandate governing deployment of MNF troops in Iraq from 31 December, 2006 until 31 December, 2007:

"Recognizing the request conveyed in the letter of 11 November 2006 from the Prime Minister of Iraq to the President of the Council, which is annexed to this resolution, to retain the presence of the multinational force in Iraq, and affirming the common goals therein: Iraqi assumption of recruiting, training, equipping, and arming of the Iraqi Security Forces; Iraqi assumption of command and control over Iraqi forces; and the transfer of responsibility for security to the Government of Iraq,

"Recognizing the importance of consent of the sovereign Government of Iraq for the presence of the multinational force and of close coordination and partnership between the multinational force and that Government,

"Welcoming the willingness of the multinational force to continue efforts to contribute to the maintenance of security and stability in Iraq, including participating in the provision of humanitarian and reconstruction assistance, as described in the letter of 17 November 2006 from the United States Secretary of State to the President of the Council, which is annexed to this resolution,"

Akenaton nowhere in the above does it state that MNF are "at war" with anyone. It does however state clearly what the MNF troops are there to do. The above took about 13 minutes to get passed in the relevant session of the Security Council.
