Obviously fictional story huh? Can you be specific? Considering you just wrote off Kyiv Post only because it is a Ukrainian source (even though you apparently consider Russian twitter feeds to be legitimate sources, as well as Kremlin controlled Russian TV which you regurgigate your crap from constantly), I have a suspicion that what you consider "fictional" about it is just that it mentions the fear of an imminent attack from Russian troops who are present in the country. Who else fears that, I wonder?
Cameron sending troops to help train Ukrainian forces and discussing fears of Russia taking Mariupol next:

NATO with satellite photographs of Russian forces surrounding (and later taking) key Ukrainian town not too far from Mariupole. U.S. ambassador to Ukraine emphasizes "Russian forces," not merely "separatists" who just happen to have all kinds of advanced weaponry:

Doesn't seem too much of a stretch to expect an attack on Mariupol by Russian forces next, considering creating a land-bridge to Crimea would save the Russkies a lot of time and money.
A normal Freeper doesn't constantly deny Russian aggression and involvement and then justify it when it finally happens. I beg the Mods to seriously analyze your posting history and note the obvious propagandish nature of it. Should Freepers have to deal with a full-on Putinista who is willing to excuse every crime the regime in Moscow commits, a Putinsita who constantly mocks his opponents, makes unsubstantiated claims, and calls everything "Kiev propaganda"?
So, again, I'm begging you Mods, check this guy out! I can't be the only one who sees the problem here.
