I was tempted to explain, in excruciating detail, exactly what will happen if thermonuclear weaponry is used on North Korea. But you were glib, so I'll be glib too: Many North Koreans, South Koreans, Japanese, Russians, and Chinese will all die. Some will die instantly, some will die over the next 15min, some will die over the next week, and some will die over the next 20yrs. We will poison the Pacific. China and Russia may respond, and if so, it will not be a gentle response.

If you think that nukes are "good news" then you probably do not understand what "good" is.
