North Korea is a totalitarian dictatorship based on the cult of the Kim dynasty.
North Korea is one of the most secluded countries in the world and the citizens' rights are subdued to the country's needs. Citizens have no freedom of speech, media are strictly controlled, and it is not allowed to leave the country.
The continuous and incessant propaganda against the US portraits the South Korean population as a victim of the American invasion; young generations live in a constant alert state as if the USA could attack any day. At the same time, the propaganda aims at instilling a great sense of pride for the country's technical progression, fueled by the Supreme Leader and culminating in the atomic bomb and the subsequent tests.
Pyongyang youngsters have been educated to be learned and knowledgeable people, especially in the scientific field, to foster the development of armaments and technology, chasing the dream of reuniting Korea in a whole and free state.
