Well if it is the case, that it was shot down by mistake by Syria, it's a real tragedy, as Russia and Iran have saved Syria from the US backed terrorists like ISIS and al qaeda . Fact is, Russia wouldn't be there if the US and their criminal allies hadn't tried to turn Syria into a Libya catastrophe.

But nothing I have said is out of the realms of definite possibility. I think a major escalation by the US is underway. And it will be a US manufactured disaster for everybody in the region, including both kurdish and Israeli people.

ps. I am not "pro putin", and I know practically nothing about military systems. But in the event of a clash between the US and any non-imperialist power, I would always hope for a US defeat.
