It should be realised by now that whatever you are being led to believe is the least likely explanation of events. According to western media, Putin is guilty of every suspicious death in Russia and of every Russian anywhere in the world. It is a comical media driven caricature. Does everyone think that there is only one possible person who might have wanted Prigozhin dead? What do we really know about the whole coup/not coup and Putin's relationship with Prigozhin?
Could there be other actors who might also want Prig dead? Would Putin, if it were him, choose such a messy and headline grabbing spectacular? Who would choose a method like that?
The ridiculous western media and establishment created comic book caricature of Putin is the propaganda that few see beyond and it is this caricature that has been indoctrinated into western media consumers that causes them to unquestioningly believe any crime attributed to him. Ask questions, lots of questions, of every premise and "fact" in western reporting. The accusations and reporting on Putin is bizarre and fantastical. Without the pre-existing premise that many in the west have(ie. it goes without saying that Putin is a tyrannical, murderous thug and probably eats babies) these stories would be dismissed if about anyone else as simply not believable or remotely credible.
In the grand scheme of things, it is also largely irrelevant. Nothing changes. The BRICS summit in South Africa and what is coming from that is of way more significance to geopolitical events than the sideshow of Prig's death. The catastrophe of the Ukrainian/NATO counter-offensive and the inevitability of Ukraine/NATO defeat in Ukraine are also ignored by Western media. Look back a few weeks at the predictions of how this much trumpeted Counter-oink was going to cut the land bridge to Crimea and bla bla. The longer this is propped up by NATO then the worse the terms will be. Minsk 2 is going to look like the deal of the century in comparison.
