>>1You ever have that one guy in school who beat at, say, soccer or something once and then left you alone but you never forgot so you always tried to ruin their day or beat them?
And then one day they actually ask you why you always try so hard to beat them because they don't remember or just don't care?
Good.
Now replace "soccer" with "the Korean War" and "guy" with USA and "you" with North Korea.
Only worse.
Because North Korea went from a communist dictatorship that was fairly frightening to an outdated husk kept together with copious amounts of spit and WH40K levels of belief in their God emperor.
It would almost be a joke if it didn't kill so many people.
I would also like to point out that nobody takes them seriously at all.
Their missile tests repeatedly fail, their "Air Force" consists of MiGs that are questionable in terms of them actually functioning and what they do have functioning are mostly Bi Planes and some WW2 Era transport planes.
They can't even figure out how to put an anti bounce mechanism in their AK variant for JMBs sake.
Their standard camoflage is one step shy of a cartoon depiction of a soldier, their tactics are still based on us being our Korean War selves, and because of this and more they'll never be takes seriously.
Not unless they actually pull something like invading South Korea, a campaign that would be brutally short and not just because of deaths but the realization of the cofactors that the outside world has food, shelter, and freedom of speech.
