I don't think crossing the Rubicon, then turning around and cutting a deal is a good move for Prigozhin. Sure, he got what he wanted, but time will tell just how long he'll get to enjoy it. Putin is a guy who has brazenly (and openly) assassinated dissidents that that had fled abroad. I don't doubt that the military folded and Putin had to back down, but I still think the FSB is still aligned with Putin. As long as that's the case, I don't think Prigozhin will ever feel safe.
