Comparitive analysis of North Korea and Iran: International Cooperation

Now that the 3 Koreans came back safely from North Korea, can a real peace truce be orchestrated between the United States and North Korea?  What does it mean about our occupation in DMZ zone in South Korea the last 67 years or so?  Kim Jong Un was supposedly educated in Switzerland under a pseudonym called Pak.  He had 2 other siblings who learned there.  He was the son of a dancer who his father loved.  He wasn't the best choice for successor but a father's favorite.  He executed his Uncle when first taking office which the public disapproved of.  He demands loyalty and is low on tolerance.  We will explore Korean history.

On another note, Iran has allowed the Atomic Energy Agency and UN inspections in exchange for oil exports and receiving needed imports.  They have cooperated internationally with the Iranian deal established by 5 countries and it was poor decision making by Trump to try to dismantle this deal which so far has been effective.  We talk about the safety of living in different countries and the perspective of governments.
