The normal day folks like us bear the biggest (by a large margin) brunt of the sanctions whereas the rich and ruling class go about their day merrily. Sure they'll encounter some inconvenience like not being able to travel to certain countries or being able to expand their businesses as much as they wish to, but they live in secluded districts with 24-hour electricity while us plebes get 12 hour electricity every day (This is just to mention the least annoying effect of artificial scarcity created by sanctions; the government couldn't get parts nor get training on technical know-how to fix/upgrade the hydro generators because of the sanctions).
A lot of people starves and the education system suffer, which sets the entire generation backward by at least 3 decades (while the rich and ruling class send their kids to international schools and then at institutions in nearby neighboring countries; some even went as far as faking their children's identities and sent them to places like Australia, Canada and even US to study).
Sanctions aren't that effective and they only hurt (and kill) the people at the bottom of the society.
Having the mot bags of rice, or the largest cattle herd only makes one feel rich if they don’t know about the existence of other luxuries. Sooner or later, someone will think I’d we simply off the king, we could have power AND an end to sanctions.
The quickest and most effective way to transform an authoritarian country for the better is to let the rich, the poor and the middle class have a taste of what quality living (to some extent, the capitalism) is like. Then their children will get proper education and things will automatically change for the better in a generation at most. I have seen that with the children of the rich and military/ruling class people in my home country; these younger generations are the ones who, using their parents' accumulated enormous wealth and influence, to make changes (some bad, some pretty decent) to copy what they've tasted in other, more developed countries.
What law was broken? Its like saying HBO breaks a law by having their shows exclusive to their subscriber base.
(Though this would all probably swept aside as soon as somebody reverse engineers the vaccine.)
