I can speak for Venezuela, and the corrupt murderer dictator party has been in power for just over 20 years. The country was completely ruined by the "corrupt murderer dictator" without any input from "the West".
The sanctions started 2-3 years ago. 5 years ago I had to buy milk and diapers for my newborn girl in the black market because the govt destroyed the economy. So don't try to "explain" the situation to me, since I'm living it in the flesh.
Not only that, they have been in power for over 20 years, with the highest oil prices ever. They've consistenly stolen all of the country's resources and destroyed the economy during all these years. The sanctions started 2-3 years ago.
