Putin has gotten to the level of Stalin in his later years. A murderous rampage. It is likely Daria Dugina was blown up by FSB, Lukoil Chairman Ravil Maganov was pushed out a window where he was being hospitalized for toxicology. I wouldn't be surprised if a Russian operatives pushed Ivana Trump down the stairs. Some of the Russian dupes on this site will say it was Zalensky, CIA, Mossad even the Illuminati. ANYBODY but Putin.
This fits the Putin pattern. It will be interesting to see what further details emerge. My guess is that the incident will simply add ochre to a dark history.
