US Ambassador Crocker: "My fear is that at the end of the day, Assad might prevail!"

"....This will be a long war. There is little the United States can do to positively influence events in Syria. Our focus must be on preventing further spillover beyond its borders. There may come a point where exhaustion on both sides makes a political solution possible. We are nowhere near that point. And my fear is that at the end of the day, the Assad regime prevails. We must be ready for that too."
