Sohee Han: Korean Cold War?

Sohee Han writes: What is the origin of the term “Cold War”? The term “Cold War” was originated from the post World War II where two major powers, the United States and the Soviet Union, fought over each other. However, this war was different from previous wars such as World War I and World War II, because unlike those previous wars, there was no arm used during Cold War. This reminds me the division between North and South Korea today. Once they were united into one country, but they are divided into two separate countries today. However, it is important to recognize that these two nations are not completely divided yet. Can these two countries be called Cold War? I doubt it. Although they are divided, they are not fighting. Thus, I don’t think the tension between North and South Korea can be called Cold War.
