It is not provable whether earlier intervention would have altered the course of Syria’s tragic history. Non-interventionists said then, as they say now, that anything that the west does only makes things worse. That we can’t prove either. What we can see is how bad things have become and it is hard to conceive how exactly it could be worse. After seven years of failing to act in Syria, we can audit where a non-interventionist policy has got us. It has been an utter disaster in every respect.
