Who better to know the horrors of war, than those that have endured it?You can assume what ever you want. You back up your claims as to how to handle the Korean problem with 20 years in the military service. I hardly see how that is an asset.
When I ask for your background, here's why: If you've been military, then you've had the opportunity to think about these situations, study them, and/or actually experience them yourself. If you've had some civilian job that required you to think about, study, and/or experience these situations, then your opinion is based on knowledge that I may not have. There are literally hundreds, if not thousands, of government personnel whose only job is to analyze data regarding Korea, China, and the rest of Asia. They've never been in the military; but I bow to their opinion because of their knowledge.
It is possible that if you have information, other than a simple "here's the way things have been for 60 years," that you can change my mind. Seriously. As I mentioned before, I'm intellectually flexible enough, when presented with new/additional information, to admit when I've made a decision based on inaccurate, incomplete, or faulty information.
If you're simply an armchair quarterback, your opinion still has merit if it's based on facts. While you cite past history, you haven't cited any understanding of the politics, social implications, and possibilities of human error (mainly based on fear) that also apply to this situation.
Here's where your opinion fails: The mass slaughter of civilians should never be an option. The condemnation of an entire people--in this case, North Koreans--is akin to saying all Baptists are homophobic anti-government bigots, because Fred Phelps has claimed he's a Baptist.
I'm not ready to kill North Korean children. If that makes me less of a person in your eyes, so be it.
