That's a lot of words just to say that the US did not lie about anything. The US did say that they have evidence that a missile was launched from the territory of Russian backed separatists. They also said it was tracked towards the MH flight and that contact with that plane was lost contemporaneously with the missile's arrival.
It's not lying to give an opinion based on currently available information.
Now that the Russian backed proxies have given back the bodies of the dead after removing them, now that they have given back the "black boxes" after removing them from the crash scene, now that they have stopped cutting into the wreckage and disturbing the crash scene, maybe just maybe a proper crash investigation can take place to determine how the plane was brought down conclusively.
But given the evidence (much of it supplied by the Russian backed proxies themselves) now available any reasonable person can only conclude that MH 17 was brought down by a missile from a SAM battery located in the Russian proxy controlled area.
Who supplies the Russian backed proxies with the training and or manpower to launch such a missile? Again any reasonable person can conclude that it is Russia that supplies the expertise or the crews. If that is true then it follows that Russia and by extension Putin bear responsibility for shooting down MH 17.
For anyone to voice that conclusion is not lying. It is a logical conclusion based on available information. I think it's a pretty widely held opinion world wide.
I was saying that USA has been accusing Russia to have been involved in destroying the plane at the first degree, which Xant denies they ever claimed. There is a profusion of official articles all around the world in every media that they did claim Russia to have done it. Exactly as everyone else did claim the other did it.
You are talking about USA/others accusing Russia to back the rebels. It is far more likely, and I am not refuting this.
Most of your post is made up of the most logical pieces of information hooked together, which then conclude with what you believe in.
Why I made that refuting post was to show that those arent the only pieces of information available, and that the US, along everyone else, has provided their share of illogical elements of accusation, and shouldnt be decreed as "never lying about anything", particularly on a topic like this.
