Putting up stiff resistance to Obama's appeals, Russia on Friday warned the United States and its allies against striking any chemical weapon storage facilities in Syria. The Russian foreign ministry said such targeting could release toxic chemicals and give militants or terrorist access to chemical weapons.
"This is a step toward proliferation of chemical weapons not only across the Syrian territory but beyond its borders," the Russian statement said.
Moreover, China remained a firm no. The European Union is skeptical about whether any military action can be effective. Even Pope Francis weighed in, urging leaders gathered here to abandon what he called a "futile mission."
Still, Obama was undeterred. He and French President Francois Hollande, the U.S.'s strongest ally on Syria and a vocal advocate for a military intervention, met on the sidelines of the summit about attracting European support for action. "It's clear that there are many countries that agree with us that international norms must be upheld," Obama said.
Holland told reporters invited into their meeting that they came to summit "wanting as large a coalition as possible," but without saying whether they picked up more support for military intervention.
"To do nothing would mean impunity," Hollande said. "We must take our responsibility" and act.
As the president pressed his case on the world stage, he was dispatching his U.N. ambassador, Samantha Power, to a Washington think tank to argue that the global community cannot afford the precedent of letting chemical weapons use go unpunished.
Illustrating the risks associated with a strike, however, the State Department on Friday ordered nonessential U.S. diplomats to leave Lebanon, a step under consideration since Obama said he was contemplating military action against the Syrian regime last week. The travel warning said it had instructed nonessential staffers to leave Beirut and urged private American citizens to depart Lebanon.
Yet even as Obama sought the global buy-in that could legitimize a potential strike, his aides were careful to temper expectations that the world community could speak with one voice. Obama's deputy national security adviser, Ben Rhodes, said the president wasn't asking his peers to pledge their own militaries to a U.S.-led strike, but simply to say they agree a military response is warranted.
"We don't expect every country here to agree with that position," Rhodes said Friday at the Group of 20 economic summit, where Obama was huddling with foreign leaders.
Standing on Russian soil, Rhodes suggested the U.S. had given up hope that Russia — a stalwart Syria ally — could be coerced into changing its position. "We don't expect to have Russian cooperation," he said.
A key status update was to come Friday when Obama, his diplomatic dexterity pushed to the max, will be quizzed by reporters in the waning hours of the summit.
A jobs-and-growth agenda awaiting world leaders gathering at the ornate Constantine Palace quickly gave way to intense posturing over Syria — at least on the surface. The leaders served up Syria as dinner conversation Thursday at the suggestion of the summit's host, President Vladimir Putin. The Russian leader has steadfastly backed Syrian President Bashar Assad and disputes claims that Assad's regime was behind chemical attacks that the U.S. says killed more than 1,400 Syrians. Other estimates are lower.
Syria dominated the nearly three-hour meal, with leaders condemning the use of chemical weapons but reaching no consensus about the proper response, said a French official in St. Petersburg. Many leaders at the dinner remained in doubt about whether Assad's regime was behind the attack, said the official, who was not authorized to be publicly named according to presidential policy.
So too was the Syrian crisis a prevailing theme in Obama's individual meetings with world leaders on the sidelines of the summit in this Russian port city.
