Well it is technically still a war, and one the US led UN side would have won if Truman hadn't wimped out at the last minute. They should have
finished the job when they had the chance, like removing a cancer early, just like they could have taken Iraq the first time. Now they have lots of
problems and the cancer is pretty much inoperable.
The most worrying thing is that the North Korean citizens are brainwashed into hating america with incredible viciousness that makes Hitler look like
a saint in comparison to Americans from the North Korean point of view. If the regime ever collapses they are going to have some major culture shock
upon seeing how the rest of the world really is.
Their nuclear weapons are basically a bargaining chip to extract aid and concessions, like an 'ace up the sleeve', if they try and use them they
would be wiped off the face of the earth, narcacisstic dictators like Kim Il Jong dont really like the idea dieing or losing power, they are all
cowards in the end, look at Saddam Hussein, talked tough and he went and hid in the ground. It's only once he realised he could prance about on tv
with a new audience without anyone trying to kill him that he grew a backbone again.
Hitler only committed suicide because he was afraid of what would happen to him when he was caught.
China, like the US, probably views NK as an embarassment from the past and something they would prefer wasn't there, like a thorn in it's side
asking for money and food all the time. I imagine they would be relucantant to get involved (officially) in another Korean war, though they would
probably be only too happy to sell them lots of equipment.
USSR and China helped out the first time around but not officially and went to great lengths sometimes to avoid being caught and the US was careful
(they really pushed it close sometimes though) not to bomb China which would mean an official war against China.
Even though all sides knew full well who was helping who there are certain lines that cant be crossed otherwise full scale war would break out,
politics and junk like that.
Interesting fact, during the later stages of the Korean war North Korean truck drivers had a higher attrition rate than front line soldiers. Due to
the US air power striking behind the lines and a stalemate on the frontline you would actually have been more likely to die as a truckdriver than as a
soldier
