You all realize this is entirely pointless, right? At best the only thing this is gonna cause is more saber rattling. NK does not have the technology to hit with the crumby ICBMs they have, and their nuclear technology is not at the point where they could actually fit it into a warhead. Plus attacking would be suicidal, not even China (their only ally) would support them at that point, there is too much profit to be had in peace at the moment (for China at least). At the very most it will be a border skirmish like the many they have had with SK since the end of the Korean War. The only purpose is to focus the attention and fear of their oppressed people on so called 'external' threats so they don't get it in their heads that maybe now would be a good idea to overthrow the government or something radical like that. NK may be outrageous, they may like to make threats and they may even kill a few SK soldiers (hopefully not though) but attacking in force or with ICBMs or something like that would bring the wraith of the whole civilized world down on their heads. If they honestly attacked SK or Japan or one of the military bases on Guam it would not wind up like the Iraq war where only a handful of countries got bullied into joining our attack... it would be everyone against NK, even China. It would essentially mean the end of NK as we know it. They just want the attention, and they hope that maybe if they make enough noise the people will stay afraid and maybe some of the new harsher sanctions will be lifted.
