That confirms it.
Anyone saying "Russia expected sanctions to be this bad" or "Trust Putin, he has measures that will make the economy just fine." is in pure Cope Mode.
The Russian economy is fucked, the war is lasting longer than Russia thought it would, is much bloodier than they probably thought it would, and an inevitable insurrection movement will take place if Russia occupies or puts up a puppet government in Ukraine, that will consume more resources of Russia's economy. NATO has become reenergized after decades of being a relic of the cold war.
Russia gambled on this to be quick deceive strike that won't bleed into the world, they'd get sanctioned sure, but it would put their economy back years, not decades.
The only winners in this will be other oil producing countries and China for gaining another pay bitch.
