Responding to your edit about Russian weaponry, it was in fact Soviet weaponry, that is also in posession of the Ukrainian army. There's no valid proof that shows it was separatist forces that shot down the plane. There's a working theory in Russia that the Ukrainians were in fact wishing to shoot down the Russian presidential plane which was going to fly a similar route, but instead ended up shooting down the wrong plane.
'A working theory'. Didn't know that was a new name for a 'totally retarded piece of fiction'.
Seperatists (including the leadership) were rejoicing on social media they shot down an airplane. They took pictures. Russian Media reported on it - and then it turned out a civilian airliner was missing, and they suddenly denied everything. They had actually shot down Antonov's before, supplying the border posts enclaves, and they were aiming for one of those again when they hit MH17 by accident.
To pretend none of that happens and suggest Ukraine would be retarded enough to shoot down Putin means you either just don't want to believe the truth or you're just an idiot. What would Ukraine gain? Giving Russians the perfect excuse to actually officially invade? Losing
all support from allies by such an aggressive act, a warcrime even? Expanding a war they were winning? How, in your head, does this theory seem even remotely plausible?
One sided? The evidence is overwhelmingly against Russia of course it would be one sided.
What overwhelming evidence? Have you read Dutch and Russian reports? Are you an aircrash investigator (you picked it up on National geographic?)?
The Dutch report stated that the MH17 was shot down by an air-to-air guided missile, made in Russia, used in about 50 other countries in the world, including Ukrainian air force. Let's say you read that, it definitely proves the Russians shot down the MH17? Where's the motive? Why would Russian air force send a plane into Ukrainian airspace to shoot down a civilian plane?
No, the Dutch report said MH17 was shot down by a BUK, made in Russia, shot from territory held by seperatists. Never, ever, was there any suggestion or claim it was done by an air-to-air guided missile. Where did you get that information? The report is clear, and you need more then conspiracy theories to debunk it.
