As I have speculated on the topic on the Russian war against Ukraine [edited and shortened for clarity):
Ad 1 and 2): a lot of Wagner personell may now join ranks based on the deal, and might still be loyal to the Cook.
Ad 2): The parts of Wagner which are operating internationally weren’t mentioned here, yet. What about them? Is the Cook still the person to do the dirty work for Putin abroad?
Ad 3) I am not holding my breath that the Dictator will be gone soon, but if you followed news from Belarus, it seems Lukasheko has had no real plan for that.
