End the Korean War
Technically, the Korean War never ended...
The armistice was signed on July 27,1953 and North Korea has been a pain in the ass ever since. And not just to the West, even the Chinese and the Russians view North Korea that way. So, with that in mind, I am going to briefly act as an unpaid adviser to the American President Donald Trump. This is how you become the greatest foreign policy president in the modern era. Pretend that the Art of the Deal works with international relations.
Step One - Hop on Air Force One, fly to Beijing, sit down and look Xi Jinping square in the eyes and say "Let's end this North Korea problem once and for all. We (America) don't want one acre of Korean land. You (China) get half of North Korea, South Korea gets the other half. We'll give Putin a slice to accelerate the process and we move toward real peace on the Korean Peninsula."
Step Two - Give Putin a call. "You (Russia) get the Rason Special Economic Zone, just for signing off on the arrangement at the United Nations after the fact." Trump then exits the negotiations.
Step Three - Xi Jinping calls Kim Jong-un to Beijing, places him under house arrest. Chinese, South Korean, and Russian troops act quickly to secure their new borders as the head of the snake has been cut off. Moving their respective armies in like Russia grabbed Crimea, the North Korean military is frozen as the army is afraid to act without authorization from Jong-un as the foreign nations move in with minimal casualties.
Use the North Korean and natural boundaries below:
China- North Pyongan, Chagang, Ryanggang, North Hamgyong provinces.
Russia- For shipping and diplomacy purposes, the Rason S.E.C.
South Korea- South Hwanghae, North Hwanghae, Kangwon, South Hamgyong, provinces
China gets land north of the Taedong River in the Nampo, Pyongyang, and South Pyongan provinces.
South Korea gets the land south of the Taedong River in the Nampo, Pyongyang, and South Pyongan provinces.
United States gets an exit strategy from the Korean Peninsula.
Step Four - Once the armies are in place, ram a resolution through the U.N. For American Hawks, try to think of the people of North Korea. In the city of Chongjin, for example. They would flourish with an infusion of Chinese money as a new port to the Sea of Japan. Life for North Koreans in a united Korea would be infinitely better, but even life for North Koreans under Chinese (or Russian) rule would, at the very least, be a little better.
Step Five - If there's no more DMZ (Korean Demilitarized Zone), there's no reason for American troops in the new Korea. Pull American forces out, there's lots of places they could be re-stationed at in Japan.
What about the North-South Joint Communiqué of 1972 stating, first and foremost, that unification shall be achieved through independent Korean efforts without being subject to external imposition of interference. Too late for that. I ask you, the reader, what is a better solution? U.S. war with China over North Korea, with potentially millions of casualties, or dissecting North Korea and building stronger U.S./Chinese relations while giving the citizens of North Korea a better life?
Blue: New Unified Korea
Yellow: Russia Annex
For those alarmed at the precedent of dissecting a sovereign state. Got a better idea without massive human casualties?
