Putin may dump Shoigu, but if he does, it’s likely that the reason is that Shoigu is being too conservative in his fight against the Neocons in Ukraine, and Putin wants the war over with, in his favor (of course), before the US November Elections, so that US voters can understand just what the Neocons are up to.
In any case, I wouldn’t get too happy if Shoigu was gone as whoever replaces him will likely make life FAR MORE DIFFICULT for Biden.
Putin blew up his best general Prigozhin.
