I only meant to point out that, in my opinion, the cynical, brutal and bloodthirsty al Assad will engineer a bloodbath, part preventive, part retribution, and part, to drive home the lesson to his people that if you step out of line, he will kill you.  I base this prediction only on his past actions of killing his own subject people wholesale, in the cheapest and most effective ways possible.  The UN can't stop this if it happens.  It was the Russians who deliberately bombed the medical-aid convey.  Putin also is heartless.

The world as a whole shrugs.  The millions of refugees have nowhere to go unless money from the NATO nations pays for their resettlement in horrid refugee camps, from which they would flee attempting to reach Europe.

Putin has coldly calculated that the US will do nothing to oppose him.  Likely, he is right.  He sees clearly that no one cares for the murdered and displaced victims of his conquering ambitions.  How far will he go?
