Incidents like this shows us that things will inevitably go wrong with increasing frequency and gravity. Furthermore, I fear regional conflicts involving mass scale conventional face-off (ex. dmz) are converting to a low operating cost high risk situations in the form of mutually assured destruction. East Asia is venturing into a potential double whammy of naval and nuclear arms race--smaller countries like South Korea are entering a phase of normalization for nuclear armament with pressure mounting from the public to have a deterrence and a back up plan yet cannot have land based missile silo's, instead relying on nuclear submarines that will host the IRBMs. The cost is much higher than the "previous generation", as smaller countries will most certainly be decimated, land based silos do not make sense.
