North Korea doesn’t have an immigration problem. No one is lining up to move to a country known for its aggressiveness and shockingly low standards of living. For decades, it has threatened South Korea and Japan with missile strikes and it now has the ability to do the same to the USA. Why is North Korea so belligerent? Why would such a small country threaten the United States? Is Kim Jong-un really that bad? Or mad? Or is there something else going on?
