Do the Russians Still Have a Chance to Score a Victory?

I think that Russia has plenty of hardware and mobilization potential to keep fighting for a long time. I mean, Putin may be removed, but then there will be a more hawkish leader who replaced it. The Russians are not stupid either. He knows some things don't work. This is why he, Wagner is allowed to do this horrible thing with the prisoners. And many countries have fought on in what looked like desperate situations for a longtime because they thought there was some chance of realistic victory,. Even a very small one.
