BEIRUT The U.S. and France on Tuesday pushed for a tough United Nations resolution to ensure Syrian President Bashar Assad's regime turns over its chemical weapons stockpile, but Assad's ally Russia demanded the West take the threat of force off the table if Damascus fails to meet its promises. The diplomatic split threatened a deal that could avert American strikes against Syria.
Assad's government on Tuesday promised to cooperate fully with the Russian plan, which calls for Syria to put its chemical weapons under international control, for eventual destruction.
Foreign Minister Walid al-Moallem told Lebanon's Al-Mayadeen TV that Syria would place its chemical weapons locations in the hands of representatives of Russia, "other countries" and the United Nations. He promised that his country would also declare its long secret chemical arsenal, stop producing such weapons and sign conventions against them.
Wary that Damascus is only seeking to avoid U.S. military action, Washington and France. France said it would put forward a draft resolution under Chapter 7 of the U.N. charter, making it enforceable with military action.
That met swift opposition from Russia.
Russian President Vladimir Putin said the plan can only work if "the American side and those who support the U.S.A, in this sense, reject the use of force."
Russian Foreign Minister Sergey Lavrov told his French counterpart Laurent Fabius that it is unacceptable for the resolution to cite Chapter 7, his ministry said in a statement.
Secretary of State John Kerry, in turn, said the U.S. rejects a Russian suggestion that the U.N. endorsement come in the form of a non-binding statement from the Security Council president.
The U.S. has to have a full resolution - one that entails "consequences if games are played and somebody tries to undermine this," he said.
A State Department official said later that Kerry would travel to Switzerland this week to discuss the deal with Lavrov, CBS News has confirmed.
The 15-member U.N. Security Council canceled plans for closed consultations on a Syria resolution Tuesday.
The developments threatened what had been growing momentum toward a plan that would allow the Obama administration to back away from military action. Domestic support for a strike is uncertain in the United States, even as President Barack Obama seeks Congress' backing for action - and there has been little international appetite to join forces against Assad.
The U.S. and its allies have insisted Assad must be punished for an alleged regime chemical weapons attack that killed hundreds outside Damascus. The Obama administration, France and others blame the regime, but Damascus says rebels - not its forces -were behind the attack. The U.S. has said more than 1,400 Syrians died; even conservative estimates from international organizations put the toll at several hundred.
Fabius said the resolution must have teeth to ensure the Russian plan is not "used as a diversion.
French authorities "don't want to fall into a trap" that could allow Assad's regime to skirt accountability or buy time, he said. Syria's credibility in accepting the plan would be determined "by accepting these precise conditions."
CBS Radio News correspondent Elaine Cobbe reports that France has thus far steered-clear of U.N. resolutions on Syria, knowing that Russia would veto any significant measures. But with this new Russian proposal on the table, Fabius saw an opportunity. The move by Paris is seen as an effort to guarantee Assad follows through with what the Russians have proposed, and will include provisions for "extremely serious consequences" if he doesn't, according to Fabius.
. British Prime Minister David Cameron said his country would join France and the U.S. in putting forward the proposal.
Russia, meanwhile, was working with Damascus on a detailed plan of action to be presented, Lavrov said. Russia will then be ready to finalize the plan with U.N. Secretary-General Ban Ki-moon and the Organization for the Prohibition of Chemical Weapons.
"We agreed to the Russian initiative as it should thwart the U.S. aggression against our country," Syria's al-Moallem said.
Moallem's comments amounted to the first formal admissions by top Syrian officials that Damascus even possesses chemical weapons. In anby Charlie Rose, Assad again refused to admit that his government has stockpiles of chemical weapons estimated by many observers to include hundreds of tons of lethal chemical agents.
Mr. Obama, who was to deliver a national address on Syria later Tuesday, cautiously welcomed the proposal. But he said the U.S. is still prepared to go ahead with strikes if it falls through. He reached back into history - and the Cold War rivalry between the United States and the Soviet Union - to underline the need for enforcement.
"The key is, to paraphrase Ronald Reagan, that we don't just trust, but we also verify," Mr. Obama told CBS Evening News anchor Scott Pelley. "The importance is to make sure that the international community has confidence that these chemical weapons are under control, that they are not being used, that potentially they are removed from Syria and that they are destroyed."
Mr. Obama said the idea actually had been broached in his 20-minute meeting with Putin last week on the sidelines of an economic summit in St. Petersburg, Russia. Mr. Obama said he directed Kerry to have more conversations with the Russians and "run this to ground."
On Monday, Kerry said Assad could resolve the crisis by surrendering control of his chemical arsenal to the international community. Lavrov responded by promising to push Syria to place its chemical weapons under international control and then dismantle them quickly, to avert U.S. strikes. Syria's acceptance came less than 24 hours later.
The Syrian National Coalition dismissed the Assad government's turnaround as a maneuver to escape punishment for a crime against humanity. The coalition had been hoping for military strikes from abroad to tip the balance in the war of attrition between rebels and Assad's forces.
In a statement Tuesday, the coalition said Moscow's proposal "aims to procrastinate and will lead to more death and destruction of the Syrian people."
"Crimes against humanity cannot be dropped by giving political concessions or by handing over the weapons used in these crimes," the group said.
Analysts cautioned that the details of how disarmament will be carried out that would make the plan credible.
"I don't think this proposal was developed and thought through. I think it came a little bit out of the blue to solve a political crisis," said Ralf Trapp, a disarmament consultant who worked for the Organization for the Prohibition of Chemical Weapons from 1997 to 2006. "Now we're in a situation where if we have political preparedness to go through with it, we now need to think in practical terms and that's where, as always, the devil is in the details."
Fabius also warned that finding and destroying "more than 1,000 tons of chemical weapons" would be very difficult and would require international verification amid Syria's civil war. He reiterated France's position that Assad must leave power: "We can't imagine that someone who was responsible for 110,000 dead, it is said, can stay in power forever."
Jean Pascal Zanders, an international disarmament expert, said any agreement depends on trust that the Syrian government is telling the truth about its weapons: "It requires full comprehensive declaration, and any failure on the Syrian government would immediately destroy confidence of the international community and probably split it again."
