Question

According to the article titled “Can Korea Be Reunited,” what is the biggest obstacle to the unification of North and South Korea?

Answer 1

I have not read about the said article but maybe this can be of help. One of the biggest challenge for the unification of North and South Korea would be the  incompatibility of governments between the North and South. The two are polar opposites. Hope this helps. Have a nice day.

Answer 2

Answer:

The main obstacles are the strained relations between North Korea and other countries apart from South Korea, including the United States & China

Explanation:

The main obstacles are the strained relations between North Korea and other countries apart from South Korea, including the United States & China. The major sticking point is that the U.S. and North Korea are in a military conflict legally, meaning that the termination of Korean War was only a ceasefire they never really addressed all the problems of that war formally. And that's why U.s. forces are still in South Korea, and this is why they are all on armed alert pretty much, they can combat at any moment.
