Why shouldn't "the West", actually many separate autonomous countries, be able to sell to whoever they want?
Literally nobody is interested in invading Russia. Nobody wants any part of that shitshow.
Russia needs to start worrying about their own internal problems, which are both significant and numerous.
I don't know, why aren't companies from "many separate autonomous countries" able to sell to Russia whatever they want? They would be punished by American and the EU's primary and secondary sanctions for that
Russia has their good friends like North Korea and Iran to depend on.
If they want new friends, maybe they could reconsider their foreign policy.
So punishing countries and companies for trading with Russia is fine, but punishing countries for selling drones to Ukraine is not. Got it.
It's just dumb for Russia to do it when they have so few cards to play.
Originally I thought you were talking about military "punishing".
