I wonder who the terrorists are. One good bet could be separatists from one of Russia’s colonies (ie. “republics” etc. People often don’t realize that Russia is still a colonialist state).
Well, separatists or disgruntled vets. Plenty of those to go around – and they’re mostly ethnic minorities too so could be a double whammy.
Revenge of the Edit: I forgot about the March 8th US embassy warning about an imminent terrorist attack in Moscow, which could be tied to IS – although the embassy didn’t give any further information than “shit’s goan go down”
