What do you think about this 2010 analysis of what the second Korean war would look like?

During the later part of my 34 year career I worked on a number of classified plans and even signed off on some concerning a North Korean scenario of them coming across the wire and how that might play out and what the response would be. Most all of that is classified so I won't get into specifics. Just let me say that if you took Vietnam and the number of lives lost, civilian on both sides as well as military, and compressed that into a six week period or so then you would have an idea of what that war would look like. That's best case scenario also and one of the reasons why North Korea does not come across the wire is they don't have enough to sustain a longer conflict nor keep the southern peninsula and much or most of that would be over run . Getting it back would be costly way beyond Vietnam for both sides and once they shot their wad they would be done. So they instead rattle their saber and try to goad and intimidate and gain any advantages they can by the actions you see them doing now. Also China is not quite the staunch supporter of North Korea that it once was. While they sometimes say they would support North Korea they also have their own mistrust of that country and what it might do. They basically say that because they partly have to since they share a long border with them but its debatable how far they might actually go with any support for North Korea.

One last thing regarding this that's important for everyone to understand I think. You can't win a war and affect large, whole scale change in a country and over its population without boots on the ground in sufficient numbers to do that. Carpet bombing, cruise missals, drones, and smart bombs in themselves won't accomplish that. That's been shown in Iraq, Afghanistan, and also in Vietnam even.
