United Nations (CNN) -- Last year, the U.N. Security Council authorized "all necessary measures" to stop the violence when the nation in question was Libya. It has come nowhere close to that on Syria, where the United Nations estimates more than 5,000 people have been killed since March. Why?
Diplomats say the answer is simple: Russia. Tensions between Russia and the other permanent members of the Security Council have always been a factor. But diplomats say that Russia's conduct in its refusal to condemn Syria, or even negotiate on resolutions in good faith, have reached new lows.
At this point, the only way Western diplomats believe the Security Council will be able to pass a resolution on Syria is with a request for intervention from the Arab League. Russia and China abstained from the vote on Libya after the Arab League and the African Union requested UN involvement in that country.
In October, Russia and China issued a rare double veto of a sanction-less resolution that would have condemned the violence in Syria.
