Yeah, Vladimir Vladimirovich is royally pissed off. And quite obviously:
'Russian President Vladimir Putin has bitterly condemned the downing of a Russian jet on the Turkey-Syria border.
He described it as a "stab in the back" committed by "accomplices of terrorists".'Notice that the first official Russian version was that the plane was shot down by the ground fire from Syrian territory. This quote changes it all. Not "terrorists" anymore but their "accomplices". The finger is pointed at Turkey now - directly and unequivocally.
Since the Syrian strife started, the Moscow-Ankara relationships were strained. The downing of the Russian jet was the last straw. And no, Putin will not do anything drastic immediately, it is not the good ole KGB colonel's style. He will bide for the right moment.
And the wannabe caliph could take it to the bank...
