Given some of the bizarre views expressed here I thought it could do with pointing out.
The issue with Assad from the start has always been the methods he has used to conduct warfare, starting initially by massacring peaceful protesters and then systematically bombing civilians.
That is what has placed him beyond the pale for the civilised world, and that alone. Had his country initially been assaulted by an extreme Islamic aggressor and he had responded accordingly I am sure the west would have viewed this war differently. But only gradually has the conflict morphed into the quagmire it now is, and I have to say that he is largely to blame for that
