I don't think NK is that stupid. They can't afford a war, they have no money, their people are starving and technologically they're decades behind SK and the US......
From an article I just read, their "air force" consists only of 678 FIGHTER/STRIKE AIRCRAFT - only 8.3% of it designed in the 1970's. The rest is pre-1970's technology. 40 mig 29's built in 1977 and 36 su25's built in 1975. The rest are leftovers from the 50's and 60's......
I totally agree .. they are a paper tiger EXCEPT .. they do have nuclear capabilities .. and they could make a terrible mess - a mess the rest of the world would have to clean up.
