I just can't see why Putin would have him killed. It makes no sense to me, he was already in prison, why make him a martyr now, before elections? As an idea elections in Russia are this month.
We also know Tucker interviewed him shortly before Navalny died and we know that Navalny chose to be in Russia. Maybe CIA wanted to not allow people to process the interview and move to martyr Navalny. There are some spicy stuff in the interview like the US blowing Northstream pipeline and Nazis in Ukraine so who knows.
Every media and politician is 100% sure Putin killed him without even considering any alternative.
My take is that the CIA killed Navalny in order to start unrest before elections or to make sure normies keep funding Ukraine.
Plot twist, I don't think he's actually dead, I wonder if his death was faked so that Putin could move him somewhere out of the gaze of the glowies so he couldn't be targeted as easily but still keep co-ordinating things for Wagner. Simultaneously allowing them both to cause a scene for the west and move the troops at the same time. It would also allow them to make Russia appear weak or having some form of infighting going on as a trap for glowies to expose some of their operatives.
You are not the first to suggest that, my wife also thinks he is not dead.
