Collapse on Russian government is a fantasy. They don’t have a huge war and spy machine just for external threats, so they are not new to this game and a lot of powerful Russians have been “dropping out of windows”. Russia is not that unified. It’s a huge country with large number of various ethnicities and many of those don’t feel very Russian. They just want to be left alone. Reality of Russias loses is startin to be weight on their shoulders and their war has been a failure and embarrassment for a long time now. Russias collapse wouldn’t even be a very favorable outcome. World would just have a one more violent shithole where people kill each other and massacre the innocent.
