Russia and China have been making moves together over the past 10 more so over the past 5. Working on creating a joint gold backed currency, joint military drills and such. Do I think russia would do it solo? Hell no, do I think if a couple of bigger countries did, or more possible some that were allies remained neutral I think it could be more of a possibility. Death by a thousand cuts is a real thing .... Also unlike in WW2 we are not the ones holding the bank notes we are now the ones holding 20 trillion IOUs
I pray to God that if it comes about you are correct.
