ISIS huh? The CIA and Ukrainians losing their war wouldn’t have an interest in trying to start a war in the Caucuses, now would they?
The attack was created by the CIA and Ukes for the purpose of opening a second front and hopefully causing widespread trouble with Russia’s moslem population.
No doubt, that's just what Vlad the Invader fears the most -- that about 40 million non-Russian Russians (mostly Muslims) would team up with maybe 40 million Ukrainians to oppose the 100 million Russians who have dominated Moscow and St. Petersburg for centuries.
As of our own CIA... well... the US government did try to warn Vlad the Invader, twice beforehand that something bad was coming.
What did Vlad do about the warnings?
He called them western threats and blackmail and ignored them.
What about Ukrainians?
So far, there's no evidence linking Ukrainians to the Isis-KP attack, though it obviously serves Russians' purposes to make the link anyway, regardless of evidence or lack of evidence.
Russians claim the terrorists were sponsored by Ukraine and tried to flee to Ukraine, however, the actual place of their capture was near Belarus, and their vehicle's license plates were Belarusian, so the alleged link to Ukraine is nonexistent.
