Don't think that this war is over. To quote Winston Churchill, This is not the end, nor is it even the beginning of the end, but perhaps it is the end of the beginning.
I would expect to see US special forces combined with some close air support hit Baathist party targets, and WND inside Syria over the next 6 months.
The Syrians will protest, but that is about all they are capable of doing. With 100,000 man force on their border, the Syrian army is no match for the US.
This is not necessarily an endorsement of a policy shift, but a prediction.
