I think the DPRK is seeing an increasingly weakening and also desperate Empire that might make even more extreme moves to maintain world power. I don’t think it’s unwise to have your soldiers deployed to a theater of war to see NATO tactics and weaponry up close, especially since it has been over 70 years since their military has seen combat. The likelihood of the US using one of its goons to strike the only legitimate government in Korea in the near future is reasonably high, I would say such actions, if they are occurring are prudent. Especially since we can see in the case of Ukraine, that the US is not worried about exposing the world to possible nuclear annihilation as long as it’s via a proxy. I can easily see the US willing to fight the DPRK to the last “South Korean”.

However, I admit I’m just a fucking moron making informed guesses, I wish Western media would have this level of self-awareness.
