The C Problem

Why did the chicken cross the road? Because it is its job; the chicken is a
road inspector.

Kim Jong-un is not the sole leader of North Korea;he is one of three
who share the highest power, and his particular responsibility is Defense.
Here are the other two.



President Kim Yong-nam

President Kim is the nominal head of state; he  receives ambassadors, signs
treaties and establishes diplomatic relations.


He has travelled extensively to Africa to represent North Korea.





Premier Pak Pong-ju

Premier Pak has a backgound in industry, and looks after internal affairs. He is known
as the purveyor of the "byungjin line" of co-developing the economy and nuclear weapons.

Here is how Wikipedia describes things. Speaking of President Kim:

In theory, he, Premier Pak Pong-ju, and National Defense Commission Chairman Kim Jong-un form a tripartite executive, each having powers equal to a third of a president's in Presidential systems, controlling foreign relations, government and domestic affairs, and defense, respectively.^{[citation needed]} The Chairman of the Presidium is sometimes considered the "number two official".^[7]

All this to say it is perhaps a gross error to expect anything other than Defense talk form Kim Jong-un, and perhaps a little silly to reproach him always leading military activities.
