When one looks closely at what NK has been doing, most people are puzzled as to WHY they did it and think it’s a crazy goverment who rather chase after conflicts and weapons while starving its large population. Many things they have done do not seem to profit their people or even the leadership. Similarly, when one looks closely at what the Khmer Rouge and Polpot did in Cambodia during their crazy and mad period, one couldn’t understand why one would do such thing to his own people.
But when you know that Polpot was following Maoist doctrine and under the influence and supports of Communist China for a very long time, then you would know why such smart and intelligent leaders of a country would kill and go against the interest of its people, chasing after conflicts and SELF DESTRUCTION for someone else interest.
