Time for some politics

It should be clear to anyone who thought about it hard that the North Koreans really had/have no intention of actually shutting down and dismantling/destroying the Yongbyon nuclear plant. The only reason I can think of that they would agree to allow the inspectors in etc is because they had already removed everything that they cared about that was portable...i.e., nothing to see remained behind.

And therefore bringing it all back would be relatively simple, as soon as it was appropriate to do so. Which it now seems to be...

You can figure the same will be true in Iran as well. Excepting that at the moment, they are busy bragging about all their centrifuges, when the time comes that they have to allow inspections, it will probably turn out that they tell us they were lying about how many they had...but that will be a lie too.

So don't be surprised by what's going on in North Korea. It was always going to happen this way. They have no intention of not having nuclear fuel processing capability, and will lie about it every time.

Personally, I think we should have gone with the invasion route a few years ago. You don't seriously think we couldn't invade NK and pound the crap out of them, do you? Station two carrier battle groups offshore, there's plenty of space there between NK and Japan, start the air assault, drop HARM missiles on their radar installations, continuous targeting of the DMZ, Patriot batteries to protect SK (because you know that NK's #1 target is Seoul (#2 targets are in Japan), not us, as in "if you attack us we'll hit your friends"), continuous air assault on all the military installations across the country (which, in fact, isn't all that big), a few diversionary sea landings along the eastern coast (also with close air support), and of course the final ground assault across the DMZ once it and all the troops on the north side have been pounded into rubble.

i.e., no land war until physical installations have been pounded flat.

You also have to figure that NK has left a few goodies behind that are going to blow up later, so we don't want to be standing around waiting at the DMZ.

Of course, what would actually happen would be that as soon as the first CBG started to get close, NK would go all crazy and launch missiles at SK, and probably throw some of their experimental stuff at us. We'd want to begin with a number of Patriot counter-missile batteries, brought in quietly. Then the CBGs. and eventually pound Yongbyon into rubble no large than peas.
