Throughout history. Sci-Fi/Fantasy has actually ended up being a rather better predictor of the future than almost any number of Academic/Government think-tanks.
But, Back to topic,
If you think the "Norks" (Not used the term much before, but am happy to use it as an easy identifier) are going to be some sort of easy pushover you are absolutely insane!
A "Boots on Ground", first strike, invasion of NK would be the worst war since the Great one!
"We" might win with overwhelming superiority, but only if "We" are willing to kill
millions of people. Are you really happy with that?
Me, I am a "Rightie" If it needs to be done, it needs to be done! 10 million enemy dead! Meh!

.
I am just not convinced that it actually needs to be done. I am a "Rightie". Therefore, I would prefer a rather more pragmatic solution, I might prefer a somewhat different, and globally less expensive (In both Human and Economic terms) solution.
