Hermit kingdom

The term hermit kingdom is an epithet used to refer to any country, organization or society that willfully isolate itself off, either metaphorically or physically, from the rest of the world. North Korea is the most commonly cited example of a hermit kingdom-like country due to its Juche state ideology which is heavily focused on isolationist and self-sufficient internal politics. Other less prominent quoted examples are Turkmenistan, Eritrea and Bhutan.
