UNITED NATIONS - Supporters and opponents of the Iraq war joined forces to help launch the country's interim government, unanimously adopting a U.N. resolution backing Iraqi sovereignty and giving the new leaders clout over a U.S.-led force.

The measure authorizes the U.S.-led multinational force for Iraq, but says the mandate will end when a constitutionally elected government takes power, expected by early 2006, or if the Iraqi government requests it.

It also gives the Iraqi government control over its oil revenues.

But whether the new government succeeds after the June 30 restoration of sovereignty will depend on its own efforts to rally support. It also remains unclear how other countries will respond to the resolution's call for troops and aid.

So far, there's been no rush to provide financial or military help, and Russia's deputy U.N. ambassador Alexander Konuzin said: "I don't think there are very many volunteers. There are enough forces - 150,000, that's enough."

The Security Council's 15-0 vote on Tuesday followed two weeks of intense negotiations and a last-minute U.S. compromise on a key French and German demand for the resolution to state clearly that the Iraqi government will control all Iraqi forces and have veto power over their participation in military operations by the multinational force.

France and Germany, key opponents of the war, also wanted the interim government to have veto power over major military operations by the U.S.-led force, like the siege of Fallujah.

But Iraq's new leaders didn't demand such power, so Paris and Berlin agreed to the U.S.-Iraqi deal requiring the force and the new government to agree on "policy on sensitive offensive operations."

France's U.N. Ambassador Jean-Marc de La Sabliere said after the vote that "France cannot imagine that the multinational force would go against the opinion of Iraq's sovereign government."

France and other council nations praised the U.S. flexibility in trying to reach an agreement. The measure adopted Tuesday was the fifth version of the U.S.-British draft since May 24.

U.N. Secretary-General Kofi Annan said the vote showed the council's willingness to come together after last year's divisions over the war to help the Iraqi people "take charge of their own political destiny."

"Obviously we are not there yet. Free and fair elections ... will be a historic milestone on Iraq's road to stability and peace," he said, but security must improve for voting to take place by January 2005.
