can we recognize the difference between civilians (people) and armed participants in conflict (military) in this discussion?
The deal is simple: when Russia stops slaughtering Ukrainian civilians, the rest of the world will stop isolating their economy. It's much like the shipping blockades that were used against the European Axis countries in WWII. Russian civilians should consider themselves lucky that the war is only economic for them.
Sanctions cannot stop this war unless they will lead to coup or state collapse (both are unlikely in near future). Sanctions put pressure on Russian elites and together with foreign aid also probably will prevent Russian victory in Ukraine.
I hope that no one is so stupid to resume business with Russia if they end the war quickly. They need to completely change their mindset from imperialism first. Otherwise it is similar to doing business with North Korea.
