No big surprise, given the alternative. But the devil is in the details and President Obama, who has failed so far to convince many people we should go to war against Syria, now faces the task of having to convince Americans that he isn't being played for the fool by Moscow and Damascus.

Associated Press:

Syria said Tuesday it has accepted Russia's proposal to place its chemical weapons under international control for subsequent dismantling.

Syrian Foreign Minister Walid al-Moallem said Tuesday after meeting with Russian parliament speaker that his government quickly "agreed to the Russian initiative."

Al-Moallem added that Syria did so to "uproot U.S. aggression."

His statement sounded more definitive than his remarks Monday, when he said that Damascus welcomed Russia's initiative.

Meanwhile, Russia's Foreign Minister Sergey Lavrov said Tuesday that Russia is now working with Syria to prepare a detailed plan of action, which will be presented shortly.

Lavrov said that Russia will then be ready to finalize the plan together with U.N. Secretary General Ban Ki-moon and the Organization for the Prohibition of Chemical Weapons.

President Barack Obama said Monday the Russian proposal could be "potentially a significant breakthrough," but he remained skeptical that Syria would follow through.

What are the chances that Assad will turn over every last drop of his chemical weapons to the UN? Syria has dozens of chemical weapons depots and facilities - many of them mobile. Who is going to certify he has turned all of it over?

Vladimir Putin, no doubt, who has never lied before. And President Assad will confirm - another famous truth teller.

That speech tonight is going to be the most interesting of Obama's career.
