Is accidental war with N. Korea Likely?

Two very different situations. I think war is far less likely with NK than in the USSR days. If for any reason it's because North Korea has such poor capability\intelligence to detect an attack and has such a reliance on commands coming from the top that they wouldn't even try to launch ahead of an imminent attack like the US and USSR were trying to do. NK doesn't have the capability to detect an imminent attack. The real risk is the USA miscalculating something NK foolishly is doing, (Like a test missile launched at the "wrong" trajectory.)

No

N. Korea has nowhere near the capabilities and nuclear arsenal. of the Soviets.
