Putin is a sociopath who murdered his own people in the 1999 apartment bombings. I'd like to see him replaced, but hopefully by someone who wants to keep Russia independent instead of a "democratic" stooge like Yeltsin.
i'm well aware of this allegation, but has it actually been proved beyond reasonable doubt?
Depends on your definition of reasonable doubt.
The
Wikipedia article has a pretty detailed rundown. Very abbreviated summary: apparent apartment building bomb discovered before detonation, prompting a city-wide emergency and hunt for the perpetrators. Half a day later,
after the perpetrators were identified as FSB employees, the narrative did a very abrupt direction change to "this was all a security exercise".
