Syria's fragile ceasefire

In Geneva today, Secretary of State John Kerry discussed the latest agreement with Russia for a ceasefire in Syria. "There are consequences to bad behavior here. In addition, if the Assad regime later on decides to break this, then that's our last shot. There will be, you know, other alternatives available to other countries and ourselves and those will have to be determined in the future."
