United Nations ? A new U.S. resolution calls for a strengthened U.N. role in rebuilding Iraq and a step-by-step transfer of authority to Iraqis but gives no timetable, according to a draft of the document obtained Wednesday by The Associated Press.

The new measure, circulated by U.S. Ambassador John Negroponte to key Security Council members, underscores that the American-led occupation is temporary and urges Iraqis to determine a date for a transfer of power.

“The day when Iraqis govern themselves must come quickly,” the resolution says.

The United States wasted no time Wednesday after it took over the presidency of the U.N. Security Council in calling a meeting to distribute the revised text to the other four veto-wielding council nations — Russia, China, France and Britain.

The U.S. presidency was a stroke of good timing as Washington campaigns for approval of the new resolution, aimed at getting more countries to contribute troops and money to Iraq.

The new draft — like the previous draft — would transform the U.S.-led coalition force into a multinational force. The United States, as leader of the force, would report to the Security Council at least every six months.

The new draft spells out that the force will ensure “necessary conditions” for adopting a constitution and holding elections.
