No I don't think they shot it down deliberately. I think everything points to one hell if a **** up, over zealous, poorly trained idioms, made worse by support from Russia. It is not just a war zone error, it brakes every bloody international law. And is a criminal case. The fact Russia aren't helping to secure the evidence speaks loudly. "ulrain and Russia should if put differences aside for a few days and both sent their own forces to work as a single task force to secure the area, and invite an international body into investigate. Boeing themself and some neutral country to oversee.
But that doesn't matter, it's you posting that all the west governments are saying it was deliberate, but I've seen nothing off the sort,
