It is absurd to the highest degree to believe that China believes in peace on the Korean peninsula, when they are so drastically affecting the balance of power on it. The DPRK is a nation that has threatened on numerous occasions to flatten our capital and slaughter every civilian with it. The DPRK has long threatened to bathe us and our allies in a sea of nuclear flame. In 1996 they said "they [South Korea] will be killed by the hundredfold and thousandfold". In 2002 they said "we will mercilessly wipe them out". Earlier this very year they promised nuclear annihilation if they were forced to disarm. This is not a stable state by any means, and to give these people with such reckless disregard for the norms of international conduct contravenes all logic.
These are not empty threats either, as of our most recent intelligence assessments, approximately 70 percent of their army is located within 90 miles of the DMZ with over eight thousand artillery pieces protected and connected by a thorough and deep network of tunnels and bunkers. Nor is our capital the only metro area threatened by a devastating barrage from the DPRK, as their tactical and short-range ballistic missiles are capable of ranging on the entirety of the peninsula, and beyond.
In closing, I do wish to note that while tensions may be ever taught between our two countries, we do not object to food and medical aid, or the transfer of agricultural technologies to the North. It is always saddening for us to watch the DPRK pour money into pointless shows of force and standing armies, when their people starve and die of basic diseases long since eradicated elsewhere. These are our cousins, our family members, separated by the curse of war and political differences. It is our hope that, hopefully someday soon, we may be able to open our borders some to free trade between us, and cooperate towards a peaceful future for all of us as Koreans.
