That the Ukrainians managed to fool the separatists into believing they shot down a civilian airliner by mistake, when, all the while, it was the Ukrainian government's well-timed air-to-air attack that did the deed? And now the separatists and their big brother to the north who supplies their toys are scrambling to escape the blame?
That's the sort of plan that only looks good in retrospect. Sane bad guys would never try it, because, a priori, the chances of something going wrong far exceed the chance you'll get away with it. Plus, I doubt the Ukrainians are actually that evil.
The thesis is that this story our govt. has been putting out and trying to implement sanctions on Russia over is totally FUBAR, and anybody who buys off on it is an idiot. Our entire foreign policy is a shambles, all over the world, and Ukraine is no exception.
