My impression from reading Institute for the Study of War’s blogs is that Putin is a “moderate” in the perverted sense. There are actually much worse people, with real power in Russia, that could conceivably take power, and he kinda keeps everyone in line.
So maybe the people in a position to depose him have no interest in doing so, not just for their own interests but because the resulting power vacuum would not be fun. And I’m sure he makes the possibility extremely difficult.
There is one guy who tried, and actually came surprisingly close: Yevgeny Prigozhin. He started a small rebellion, and it might’ve worked with a slightly different roll of the dice. He seemed kinda populist and Trumpy to me, with a lot of grassroots support from the more militant factions in Russian politics, especially on social media… if Trump was the leader of a notorious mercenary outfit.
He died in a plane crash exactly 2 months later. I’m sure its a total coincidence.
Trump forgot about the Streisand Effect.
He was a very effective user of it, and now the tables have turned.
