The video from Kafranbel, a rebel-held village in northern Syria, has been sent by e-mail to members of the United States Congress and posted repeatedly on their Web sites — often in long strings of comments about Syria that have flooded unrelated posts about health care or the openings of new constituent offices.

Catholics worldwide held a day of fasting and prayer for peace in Syria joined by Jews, Muslims and Orthodox Christians, with Pope Francis set to host a mass vigil on Saturday. Francis has called for a "cry for peace" to rise up around the globe and has said he will attend the four-hour prayer session in St Peter's Square. Earlier in the week he wrote to leaders of the G20 leading world economies urging them to "lay aside the futile pursuit of a military solution".

Pope Francis isn’t eating much today—he’s fasting and praying for Syria, and hundreds of thousands of Christians across the globe are joining him. Today, during a five-hour evening prayer service for Syria in St. Peter’s Square, Pope Francis challenged the tens of thousands gathered there to rethink approaches to conflict as the fighting in Syria escalates and as the United States and France contemplate a military strike.

A nation's credibility is of course important in the conduct of foreign policy, but as a goal of military action, it has a troubled history. Focus on defending U.S. credibility in the mid-20th century blurred the difference between vital and non-vital interests, ultimately leading to American intervention in remote places like Korea and Vietnam.

I'm sometimes asked how, as someone who testified 42 years ago against the Vietnam War in which I had fought, I could testify in favor of action to hold the Assad regime accountable today. The answer is, I spoke my conscience in 1971 and I'm speaking my conscience now in 2013. Secretary Hagel and I support limited military action against Syrian regime targets not because we've forgotten the lessons and horrors of war -- but because we remember them.

"I belong to the Syrian people," Syrian president Bashar al-Assad told the French journalist George Malbrunot, of the newspaper Le Figaro, earlier this week. "I defend their interests and independence and will not succumb to external pressure." Yes. That's what he said. There are many, many caveats to that little assertion, obviously, but one of the most noteworthy is this: The message wasn't just sent from President Assad to George Malbrunot. It was also sent from President #Assad to George #Malbrunot.

After months of standing firm (and almost alone) against international intervention in Syria, by the end of August, Russian President Vladimir Putin seemed resigned to the prospect of a U.S. strike against Bashar al-Assad’s regime. To be sure, he was not happy about it, but the use of chemical weapons against civilians in a Damascus suburb appeared to have brought the current phase of the Syrian crisis to its inevitable climax.

"I am French," explains the young man in the YouTube video carrying a Kalashnikov and wearing a kufiya cotton headdress as he sits in front of a waving black-and-white flag of al Qaeda. "Oh my Muslim brothers in France, Europe and in the whole world, Jihad in Syria is obligatory," says the fair-skinned youth with sandy hair, wispy beard and southern French accent, imploring viewers to join him and his younger brother in Syria.
