Similarly, I am not an expert on sanctions, but I can tell you that the situation in the country is dire and it was largely precipitated by, in addition to political factors, serious economic contraction and episodes of hyperinflation, shortages of basic commodities and access to services that one would expect of a functioning government. All those things are going to be impacted by sanctions whenever you apply them to a country.
We've seen the impact of those kinds of sanctions in other places in the world. It's not for me to determine whether that's an effective tool, but just to say that perhaps it certainly isn't going to make the economic situation any better.
