In order for the country to survive the politics of North Korea will have to change in the next 100 years.In this day and age where globalization rules the isolationist policies of North Korea just won't survive.What they need to do is become more open so they can use the resources of other countries.
From the perspective of the North Korean leadership, why fix what isn't broken? For them, everything is fine. This is the problem with a government that is out of control. They won't change themselves. The people will have to find a way to get control of their country. Unfortunately, this will cost a lot of blood and tears, but maybe not so much as they've already shed.
No, I do not think that North Korea will change in the next 100 years. The country has been in the state that it is for decades. Many have wanted to help the country, but the leaders are determined to keep the country as it is. As long as the reigns of control remain in the same family or those that are closely associated with the ruling family, North Korea will continue on its lonely path.
North Korea is the most successful Communist state and it will not likely change its policies in the next hundred years. The country has already had two changes of leaders in its history without any problems. Despite international pressure for the country to open up, it has not responded and has shown no signs that it will.
No, I do not think that the politics of North Korea will change in the next 100 years, because there are too many threatening politicians willing to fill a power vacuum. The people in North Korea have been brainwashed for so many years, that they do not know the difference. They cannot rise up and defend themselves.
