As sure as night follows day.
Whenever an incident involving large scale loss of life occurs - occasionally intended, but the vast majority blunders - involving Russia, which attracts widespread condemnation their quite extensive and well funded propaganda organisation goes into hyperdrive. Principally the St Petersburg Internet Research Agency. We then routinely see a flood of propaganda, which usually takes the form of it being absolutely nothing to to with them, but rather a "false flag" incident.
We saw them using it in Syria, to protect Bashir Assad, after his forces carried out chemical weapon attacks on the civilian Shia population. The "rebels" did it against their own people to make him look bad you see. It worked superbly against that great ditherer, Barrack Obama.
We saw it in July 2014 when MH11, a Malaysian civil aircraft, with a total of 283 passengers including 80 children and 15 crew members, was shot down over Donetsk in Ukraine (post, the Russian invasion and annexation of Crimea). I.R.A. propaganda claimed initially it was shot down by a Ukrainian fighter, having been diverted by their national ATC to an isolated area. Subsequently, they blamed it on a Ukrainian BUK missile system. Nothing to do with Russia you see. All debunked, in an extensive investigation by the Dutch aviation authorities. A year later, so ignored of course.
Now we see it once more in Ukraine, where umpteen reports from diverse sources reporting on atrocities committed by retreating Russian forces from the North of the country have emerged. Not to mention the slaughter of people by sustained artillery/rocket/bombing in the like of Mariupol.
Today - an incident which attracts yet another rebuttal from the Forum's principal Russian apologist - details a large number of Ukrainian deaths and injuries at a railway station in Kramatorsk after it was attacked with Russian rockets.
It's become a standard response to absolutely any act of butchery. Meant primarily for domestic Russian consumption - where all anybody hears on national media is the voice of Vladimir Putin. That it was all perpetrated by the people being attacked's own government - to make the humanitarian, peace loving, Russians look bad. Gleefully picked up and regurgitated by a host of people on Social Media who's view is that everything which comes out of the Russian media is gospel and from the West lies. Between posts that is where they're accusing people of not being able to think for themselves.
