You have undisputed evidence to support that claim that they did not have a BUK system. Contrary to your "no evidence" line, there have been mounds of circumstantial evidence to support that they did, in fact, have access to a BUK system. And, yes, it exists, even if you close your eyes, plug your ears, and scream "NANANA-I CAN'T HEAR YOU!" every time it becomes presented.
No, I won't repost it for you. It's been posted ad nauseum in this thread. You're welcome to counter this with whatever bullshit line of your choosing, but it doesn't take away from the fact that it exists. If you're really interested in showing how undeluded you are compared to the general consensus, why don't you go back through this thread, pull out of all the supporting evidence for the pro-Russian rebels having a BUK system, and dispute that with other evidence? That doesn't mean "this is bullshit" or any form of that will count. Just because you disagree with it, doesn't make it false.
I guess it must be fun for you to live in a world where everything has to exist the exact way it is portrayed in your mind, else it doesn't exist at all. To me it seems like a life lacking in critical thinking and possibilities, but YMMV. I guess your blissful ignorance is just that--blissful.
