Wow. A NATO member nation carries out the "official investigation," and comes up with a result which -oh my- is exactly what the US state department said the day after MH17 was shot down (no investigation required for US intelligence).
Do you honestly believe the US/NATO would allow any other conclusion to be reached by an investigation run by one of its own member states when its sole purpose for existence is to oppose Russia?
According to official rules, Ukraine is the country which should have taken the lead in the investigation, they left it up to The Netherlands, but I guess you would find the outcome more credible if Ukraine was in the lead
The US had a lot of monitoring planes in the air at the time, and continues to monitoring the planet detecting missile launches, so yes they were looking live as things were evolving. The Dutch-let JIT investigation team had to have collaborating evidence, on source isn't a source and since Russia's 4-y/o response is quite predictable, "I didn't do it, he did", they must have evidence 4 times as good.
Must be a shocker, but Dutch investigators are truly 100% independent. So they could care less what the Americans think and their US state department. I know in Russia things are quite different and prosecution is more like a tool in the Putin arsenal of controlling the Russian state and its oligarchs but not much so in a free society.
You continue to bash everyone, except your beloved Russia, ignoring the facts. Let me finishing up, by this quote:
