Kerry’s Offhand Proposal on Syria Arms Welcomed

A seemingly offhand suggestion by Secretary of State John Kerry that Syria could avert an American attack by relinquishing all of its chemical weapons received a widespread, almost immediate welcome from Syria, Russia, the United Nations, a key American ally and even some Republicans on Monday as a possible way to avoid a major international military showdown in the Syria crisis.

While there was no indication that Mr. Kerry was searching for a political settlement to the Syrian crisis in making his comment, the reactions appeared to reflect a broad international desire to de-escalate the atmosphere of impending confrontation even as President Obama was lobbying heavily at home to garner Congressional endorsement of a military strike.

Mr. Kerry’s suggestion — and the Russian and Syrian response — also seemed to represent the first possible point of agreement over how to address the chemical weapons issue that has threatened to turn the Syria conflict, now in its third year, into a regional war.

Asked at a news conference in London if there were steps the Syrian president, Bashar al-Assad, could take to avoid an American-led attack, Mr. Kerry said, “Sure, he could turn over every single bit of his chemical weapons to the international community in the next week — turn it over, all of it, without delay and allow the full and total accounting.” He immediately dismissed the possibility that Mr. Assad would or could comply, saying: “But he isn’t about to do it, and it can’t be done.”

However, in Moscow, Russia’s foreign minister, Sergey V. Lavrov, who was meeting with Syria’s foreign minister, Walid al-Moallem, said in response that Russia would join any effort to put Syria’s stockpile of chemical weapons under international control and ultimately destroy them.

Mr. Lavrov appeared at a previously unscheduled briefing only hours after Mr. Kerry made his statement in London, seizing on it as a possible compromise.

“We don’t know whether Syria will agree with this, but if the establishment of international control over chemical weapons in the country will prevent attacks, then we will immediately begin work with Damascus,” Mr. Lavrov said at the Foreign Ministry. “And we call on the Syrian leadership to not only agree to setting the chemical weapons storage sites under international control, but also to their subsequent destruction.”

Mr. Moallem said later in a statement that his government welcomed the Russian proposal, Russia’s Interfax News Agency reported, in what appeared to be the first acknowledgment by the Syrian government that it even possesses chemical weapons. The Syrian government historically has neither confirmed nor denied possessing such weapons.

In quick succession, the idea of sequestering Syria’s chemical weapons stockpile was also endorsed by Britain’s prime minister, David Cameron, and the United Nations secretary general, Ban Ki-moon. Mr. Ban said he might propose a formal resolution to the Security Council, which has been paralyzed over how to deal with the Syria crisis from the beginning.

Mr. Cameron told lawmakers in London that if Syria handed over its chemical weapons arsenal for destruction under international supervision, “it would be hugely welcome,” news agencies in Britain reported.

In Washington, Representative Mike Rogers, a Michigan Republican who heads the House Intelligence Committee, expressed cautious support for Mr. Lavrov’s response. “Just the fact the Russians have moved, tells me having this debate on military action is a having a positive outcome,” Mr. Rogers said in a telephone interview.

Mr. Rogers still said Congress should vote to support a resolution backing United States military action as a means of increasing American leverage on the Russians.

“So far, the Russian rhetoric does not match their activity on the ground,” Mr. Rogers, alluding to the Russian supply of arms to the Syrian army. “They’re going to have to prove they mean it.”

Obama administration officials have discussed the idea of presenting Mr. Assad with an ultimatum. But officials are wary of giving the Syrian leader an opportunity to play for time, and carrying out inspections to make sure the Syrian government has not retained hidden stocks of poison gas as fighting rages appeared to be a near impossibility.

Mr. Lavrov went into more detail than Mr. Kerry’s suggestion — which Mr. Kerry’s own spokeswoman had described as more of a rhetorical exercise rather than a proposal.

Mr. Lavrov said Russia was proposing that Syria join the international Convention on Chemical Weapons, which bars the manufacture, stockpiling and use of poison gas.
