Saying that sanctions helped the Russian economy is an absolutely wild claim to make, and not one I have seen made from a single credible source.

Double digit inflation despite a central bank baseline rate of over 20% is absolutely terrible. GDP numbers are only staying up because their government is spending a massive amount on the millitary and running huge deficits. The situation is very bad and getting worse. Millions of prime age workers have been pulled from productive work to supply the army and serve as assault troops. Hundreds of thousands have been killed or disabled.

The soviet stockpile drawdowns appear to have peaked which will put even more strain on the system. Nobody knows when the system will collapse but it will get there sooner or later without some major changes.
