Lots of more popular support for ending the embargo on Cuba, and there's even a UN vote where all countries aside from 5 voted to ending the embargo on Cuba, but there's very little international support for ending the sanctions on North Korea. Does anyone know why this is? Surely if you want to end sanctions on Cuba, it's only logical to want to end sanctions on North Korea too?
There's a really good essay on Red Sails which discusses this in some detail.

The tldr as well as a short answer to your question is that the propaganda may be seen through, or at least suspected as exaggerated in some way, but it doesn't matter because it matches up with a person's real and perceived material interests.
