The nation is falling a part, and so is their military hardware.
Do you have any evidence to support this assertion? Or are you just parroting what your government told you to believe?
I have no first hand knowledge of North Korea (and I doubt you do either). But I grew up in America and heard lots of stories about the terrible conditions in Communist China. Then I went to China. I lived there for years, made dozens of friends, married a Chinese woman, started a family, started a business. It was absolutely nothing like what I was told. So I am extremely skeptical when the US government tries to shovel propaganda in my direction. Especially when there is objective evidence, such as satellite photos, that contradict the official party line.
