It cuts both ways.
In no way am I believing his account. But the man is there (he's real), and his account is there.
Whether he is or not, the man exists and can be called as a witness.
Haven't several military aircraft been downed over eastern Ukraine recently? And haven't they bombed civilian targets?
A plane. Which plane was he referring to, and when did it happen? Do you know for a fact that they weren't discussing the downing of another plane recently, and Ukraine isn't using this prior intercept as propaganda? I don't know this yet.
Yes. So does Ukraine.
If the recording is real and hasn't been tampered with, it indicates the reporting of "an event" (but which?). Furthermore, rebel leaders have stated both men in the recording are real but that both live and fight in east Ukraine.
Simply - more. You surely understand this is a gift to Kiev, and to certain interests in Washington demanding that Europe do more (stronger sanctions against Russia etc), right? Now this doesn't mean they did it, but it should be borne in mind till more facts come in.
I'd tend to agree with you there. But am still open-minded about other possibilities.
