You just open company in Brazil or Argentina and you can purchase whatever you want. Before 1989 communistic countries were overcoming CoCom restrictions in this way. Russia is doing this successfully since 2014. Surely Iran, North Korea are doing the same, this is really a no brainer and today and it is not even hard or costly, as nobody needs to physically travel, money transfers go through Kaiman, Netherlands Antilles, City of London Corp., etc. Nobody is able to track them.
More. Nobody even tries to hide anymore. Germany is openly purchasing Russian oil, branded as "Kazakhstani", through Druzba pipe. The Netherlands is buying Russian gasoline branded as "Indian". France is buying Russian LNG and it is not event trying to pretend that it is not Russian.
We will wait very long for those who will pay this $1M fine or go to prison.
