Nice. I would wish them well, but after all the horrors they've committed themselves, I'm not really sure there will be a 'good' outcome to any of this.
Here's a couple early sources. This has been a growing possibility for some weeks now. It's hard to see a walk back now. Definitely seeing different interpretations of whether this is an effort to seize control of the military command and then continue the war, or whether it's an effort to usurp the Putin regime entirely.
It seems like there is a genuine coup in progress though.
