Putin is having a hard time with Ukraine, seems like he'd have a struggle moving on to other countries. I guess he could bomb the other countries into submission, but I don't see how he occupies the countries. He's also likely going to have to find some source to fund all his expansion activities. Sounds like he is already getting squeezed financially. I guess he could resort to nuclear extortion.
Or brings it to reality quicker. How do you know Putin will keep going? Your gut?
My gut says if this goes on much longer you will get what you want soon, not in a month.
He doesn't have free reign in Russia the way the Kims did in North Korea. The oligarchs hate losing their soccer teams, yachts, reserves and med holidays. If Putin starts without justification trying to hold nuclear hostages, at that point the oligarch, probably together with the FSB, would take him out. North Korea is like a cult. Russia is organized more like the mob.
