ELI5: As an American, Why could I visit North Korea, but not visit Cuba?
gpt
Because your own government forbids you to visit Cuba, but not N. Korea, as part of the over 50 year old embargo.  Cuba is fine with your visiting, though.  It's just tourism money from their perspective.  N Korea is another matter.  They may or may not let you in at all.  They simply refuse a lot of people, apparently.
