Such talks (about Russia "blowing up sooner or later") were on the agenda in the 90s. But as time passes, it becomes more interesting if the USA is not gonna blow up any time soon...
yes, since end of 90s when Putin started his climb to power and restoration of empire. every tyranny blows up at some point.
USA might blow up too but there is smaller chance of that happening. people in USA are actually enjoying a better country by most standards, economy of USA is huge and military power is unmatched by combined power of next couple countries on the list. those are not signs of "this country will fail any time soon". yes people can hate how USA is getting involved in all kinds of conflicts but do you see USA annexing territories or setting up puppet governments anywhere? difference between USA intervention and Russia intervention is that USA eventually leaves.
Russia on the other hand has practically destroyed it's economy by dutch disease making 70% of budget come from selling oil and gas. Things Russia is producing cannot compete on any market outside of Russia. It is increasingly becoming a police state where you can't even gather to protest against anything. Any opposition is being squashed and opposing media being taken over or closed or banned. And now you have russia fueling terrorism war in eastern part of ukraine, russian weapons are being found in possession of HAMAS and open support of tyrannical regimes like Assad's. I urge you to just go through american billionaires and russian billionaires and compare how did they amassed their fortunes - this is the real difference between USA politics and Russia politics.
