Gilly says "When you don't know how to proceed, don't proceed until a path is revealed or at least do so with extreme circumspection which is what Obama has done"

What he means is do nothing, or at best nothing effective, while ISIS continued to expand.
Putin offered a sharing of intelligence and a coalition to contain ISIS, but President Obama (or his masters) knocked it back, saying that President Assad must be removed before any co operation could take place. Putin's response was to say that it was up to the Syrian people to elect their leaders, not the US or other Western interests.

The major issue is the containment of ISIS and co operation is in the interests of us all.

"Blood soaked murderers" very theatrical! Assad was fighting a well armed and well financed(by the US) insurgency, what the fuck did you expect him to do? If he had failed the millions of inhabitants of Damascus would have been butchered without mercy.
When faced by such an insurgency you everything at your disposal to protect your people, not pea shooters!

All western "liberal democracies" would do exactly the same.
