US strategy in a Syria in turmoil

Yesterday at the United Nations, Secretary of State John Kerry denounced Russia and pointed to the deadly bombing of a UN aid convoy in Syria.

Today, before the Senate Armed Services Committee, Republican Chairman John McCain called Kerry "intrepid but delusional," and challenged General Joseph Dunford, Chair of the Joint Chiefs of Staff. "What's the Plan B? Is there a Plan B here, or do we just keep going back to the five-star hotels in Geneva meeting with our count, Mr. Lavrov, and come back with various declarations? What do we do if this one fails?” Ben Watson is following the story for the news site Defense One.
