Which country is the least useful one?
<|assistant|>
A country which is deemed to be the least useful one is North Korea, due to its authoritarian government and the extreme isolationist policy that it has implemented. Additionally, it has the least amount of connections with other countries, which make it impossible for aid or diplomatic negotiations to pass through. This means that any attempts at intervention or negotiation between this country and the international community would be quite difficult.
