I suppose a kid in his early 20s is "entitled" to be a leader. It is no different than kings and queens and the princes that get propped up into power. However, these people are just figure heads. In reality the power resides in a technocratic apparatus, a system of bureaucrats that exercises power on behalf of the figure head.

Well, the technocratic, bureacratic apparatus is the same in every government. Western pseudodemocracies have "cabinets" with their ministers and secretaries. The difference is that in western pseudodemocracies people vote to chose their dictator for a few years, they have the option of calling him names if they don't like him, and finally he leaves only to be replaced by another one. In North Korea the dictator is imposed, nobody can call him names and he leaves only when he is dead.

The military bases are there because of fear that war could break out again. After all, North and South Korea never declared peace. They live under a cease fire, and they are both too radicalized in their ideology to concede peace to each other.

Is North Korea a threat? Historically it is and it is not. North Korea never attacked the USA, or any European nation, or Japan. If anything, it was always the other way around since it was the empires that attacked the weaker nations. The Japanese empire abused Korea for centuries,as did the Chinese empire and the Mongolian empire. However, North Korea did attack the south with the backing of the People's Republic of China and the Soviet Union. Our western empires killed 3 million North Koreans, and at the same time they want North Korea to trust the west. Would the USA or the UK trust a country that killed 3 million of their people?

Western empires want North Korea to abandon its nuclear program, even though those empires make no effort to abandon their own. Western empires deplore WMDs, even though they have arsenals that could kill every living thing in this planet. The West expects North Korea to be sane, without admitting the insanity of their own behaviour.
