Back when Russia backed forces shot down a passenger plane over Ukraine killing hundreds of innocents, the Russian media came out with multiple alternative theories about what happened. Some of them were so bizzare you would have to wonder how anyone would find them credible, yet government propagandists just kept pumping more theories out. It did not matter that they could not all be true. How i saw it, was by pumping out multiple versions of what supposedly happened, it made the real version into just one more story among the masses.
Likewise, with the recent killing by US forces of ISIS leader Baghdadi, the Russian media came out with a whole bunch of arguments why it could not be true, or casting doubt on it. One that surprised me was they said there has already been multiple claims at various times that he has been killed. This was self depreciating, as it was Russia itself that had made those false claims. But none of that seemed to matter to the propagandists. And all this despite that they must have surely known that the truth would eventually be verified.
A link to one article, but each article only proposes a few of the reason put forth by Russian govt. why they said the US was lying. https://edition.cnn.com/politics/liv...35a29aac4e9eec
