Russia has advanced from “upper middle” to “high” category on the strength of its economic growth.
This economic growth happened even after the US and its allies levied thousands of sanctions against Russia over the Ukraine conflict, openly stating that their goal was to destroy the Russian economy and provoke regime change in Moscow.
The US and EU did in 2 years what Putin not only couldn’t but didn’t ever really want to do in over 20 years, and Russia is better off for it.
