Only the very first signal/command is important. Once started, then non-stop, the rest would be WW3!
The biggest factor in the conflict would be intervention from Russia or China.
NK is only tough on paper. But deploying their weapons in combat is a lot different than doing it in a training environment.
NK has not been at war since 1953. The U.S has been in a constant state of war since
7 December 1941. And we have been engaged in multiple conflicts since 9-11 2001.
NK looks good on paper. But when you probe deeper they are a joke.
They have 5000 tanks, but many of them are T-62's from Russia that were introduced in 1961.
They have 900 aircraft but their inventory includes a MIG-9 from the first Korean War, a bi-plane and numerous MIGS (19 and 21) that are 30 plus years old. .
They have 75 submarines.... but 50 or so...were bought from Russia about 10 years ago. Russia (USSR) mothballed them in 1962.......no, that's not a typo.......because they were obsolete. I guess they were maintaining them for a national emergency and only a moron like Kim Jung Un would buy them.
They have a mandatory military service but much of their time is spent farming and building roads. Their soldiers are under-trained, undernourished, undersized and lack the motivation of an all volunteer force like the U.S.
And when they return home from their service, they have to live with the fear that they don't piss anyone off so they don't get sent to one of their re-education camps.
But, I don't think it will get that far. Kim Jung Un has pissed off a lot of people. Russia, China Japan and South Korea. I think his days are limited. Someone in NK or our govt. will ensure his life ends prematurely.
