North Korean leader Kim Jong Un has replaced Gen. Pak Su Il, his top general, with Vice Marshal Ri Yong Gil. Those changes suggest a reshuffle of the country’s military leadership. Other key officers also experienced shifts in roles during a meeting of the Central Military Commission. Mr. Kim’s reshuffling of leadership follows that of preventing subordinates from gaining excessive power.

The move is seen as an effort to keep control over the country's leadership rather than something tantamount to a punitive measure. Ri Yong Gil's promotion reflects his growing stature within the North Korean military hierarchy.

A reorganization happens amidst heightened regional tensions. Recently, examples of North Korea’s military rhetoric include threats against US reconnaissance planes and showings of bullet-proof missile technology. Kim’s orders for war drills featuring new weapons also demonstrate the regime’s focus on military preparedness.

In response, South Korea has planned a nationwide civil defence drill. The exercise is made in order to instruct citizens about possible provocations from North Korean authorities.
These are further developments that underscore the enduring challenges on the Korean Peninsula. No formal peace treaty was signed after the armistice that ended the Korean War 70 years ago, leaving both Koreas in a technically unresolved state of conflict. As North Korea shapes up its military leadership and ramps up its rhetoric, that region is still vigilant.
