Did you see that tweet on how the sanctions affected Iran? Something like 6% contraction before the sanction's effectiveness declining a lot within two years.
There's suffering, but no real collapse, as people want to believe will happen to Russia's economy
Russia will have the same experience except the US and EU purposely carved out exemptions for energy and grain because a sudden cutoff will fuck over many countries not in the West. Sudden grain/gas shortfalls + bad timing with weather/other events is what gives us things like the Arab Spring and a few civil wars.
And China-Russia trade is the wildcard in all this.
