On the other hand, the Iraqis weren't starving either.
Arguably, they were; UN sanctions. I'd imagine the regimes in charge at both countries would blame the economic / food problems on the US, anyways. It's arguable that, in N.Korea this would be more persuasive due to the personality cult they developed around the 'glorious leader' (of course, I recognise it's impossible to judge how pervasive that cult is, given the lack of free press to gauge opposition, and the oppression of those who do, would).
North Korea is going to collapse of its own accord sooner rather then later. Militarily they barely even rate consideration: they can put an impressive number of troops in the field, but these are poorly equipped and even more poorly trained. They are poorly paid. Poorly fed. Indoctrination or not, they are incapable of effective guerilla action. They can barely sustain themselves in garrison; prolonged time in the field is beyond their capablities.
North Korea's nuclear capablity is not impressive. They have never actually detonated a weapon. Considering the current state of their military, whether they actually have the capablity to deliever a warhead to Seoul, let alone Japan or Guam (the only US territory within the theoritical range of their missiles) without a few weeks to prepare is questionable. They like to show off those Nodong-1 and Nodong-2 missiles, but how many of them actually work? Probably not many. Those that do are almost certainly not kept fitted with nuclear warheads considering the level of paranoia the regime has about its own citizens. They would need at least a few hours to get the warheads out of storage, fit them to a missile, and launch them. Whether they'd have any missiles left by that point is questionable.
Even assuming the Nodongs launch with nuclear warheads attached, it's questionable they'd actually reach their target. South Korea has long been interested in missile defense, for obvious reasons, and the Nodong series lies within the "theater ballistic missile" realm: a realm that the Patriot missile can intercept. After the Gulf War upgrades were made to the Patriots so that they would offer a better showing in this role, and South Korea has a lot of Patriot batteries. So does Japan, and the JSDF's navy has a number of Aegis-equipped destroyers as well. Aegis could always intercept TBM missiles; they tested that in the '80s. Upgrades to the SM-2 missile after the Gulf War increased its capablities in this role. The SM-2-ER Block IV was specifically developed for the purpose of intercepting a ballistic target. Japan eagerly bought about a hundred of those.
The real danger lies not in their nuclear capablity, but in their much less publicized but much more extensive chemical arsenal. This is not a serious threat militarily; the US and South Korean armies have trained for a generation and more to operate effectively on a battlefield saturated by chemical weapons. The problem is that they could potentionally kill most of the civilian population of South Korea, and maybe even a sizeable chunk of Japan's civilian population to boot, with those weapons. Their delivery systems are much less complicated, much more reliable, and much more numerous. The North Koreans have thousands of FROG-series rockets, cheap and reliable in function if not accuracy, and hundreds of older, lesser ballistic missiles that were made to carry chemical warheads.
All the (US) wargame simulations have predicted (in an NK invasion started war) that the North Koreans could be repulsed prior to reaching Seoul, then defeated, but only at the cost of massive casualties. that's my point; I'm not saying the US couldn't win a war, but that to do so would effectively destroy the purpose of that war - i.e. a war of regime change that more or less destroys a country is not one that is politically viable.
What I mean by militarily infeasible, is that it's impossible (IMO) to determine a military strategy that would result in a politically acceptable victory. I think the US knows this, and hence would not attack North Korea unless provoked (and properly provoked, i.e. by an NK attack, not by some made-up provocation).
Whilst the entire NK military might not be technically adept, I believe that the sheer numbers would be enough for damaging human wave style attacks; and that there would be a sufficient number of hard core, dedicated fanatacists to run a damaging guerilla campaign post-war.
I don't know if the higher-up commanders are sufficiently indoctrinated or loyal to use NBC weapons; but at the same time, you can't plan a war based on the assumption the enemy will
not use their most powerful weapons. That's another reason why I don't believe a military option is feasible.
Finally, I don't think the US has enough spare troops, or had enough, to fight a war and occupy the country (even before the Iraq war), given the difficulties in post war Iraq (which had a smaller military).
