"It pains me to say it, but I've always been thoroughly bewildered by North Korea. They cannot be threatened, as they feel themselves superior to the one making the threat. They cannot be reasoned with, and most importantly, they are 100 percent convinced of their righteousness, so they cannot be bought. Megalomaniacs with delusions of grandeur are notoriously difficult to handle, but how generations of them can follow one another is beyond me."
