That's my point. Whenever there is any sign of cooperation something happens to end it and I believe the United States are the ones that make said things happen in a lot of cases. If North and South Korea were left alone to confront their issues they just might realise that there really isn't any reason for them to be at war with each other and the only country that benefits is the United States. Divide and rule. The oldest tactics are often still the most effective. Forgot to upvote your post so will do it now.
