My point is that anytime North Korea is brought up as a serious threat, you should question how and why and who, it would benefit from the world fearing a paper tiger.
I was just sharing some funny, ridiculous myths that most North Koreans actually believe about their leader, not making any kind of statement about their military prowess.
But now that the conversation has gone in that direction, I think it would be foolish to not take the DPRK seriously on their threats to someday attack the US with nuclear weapons. They may not have the ability to do so right now, but it's only a matter of time. Sanctions against the North Koreans have been surprisingly ineffective. They are extremely resourceful and have cozied up to all of the US's enemies for illicit cargo and conduct huge amounts of money laundering out of Morocco.
Now that Russia has been buying literal TONS of weapons from them, North Korea has had a massive, recent cash infusion, which they will obviously put towards their weapons programs and not towards their nationwide poverty/starvation problem. My other main concern is that their safeguards against premature or accidental launches of missiles may not be up to code compared to most other nations with similar or identical technology. I'd hate for their carelessness during a test to end up causing destruction to one of its neighbors. This could lead to, potentially, the next big war throughout the world. They have already been reckless by, as
@Mick! pointed out, firing missiles over Japan.
Also, let us not forget that North Korea has the largest active military on the planet by a long shot and that it is believed they have dug tunnels deep beneath the DMZ separating it and South Korea, where it is prepared to send a flood of weapons and military personnel into the heart of South Korea should conflict ensue. They also have an enormous weapons surplus that is so enormous that they have been able to, again, sell metric tons of weapons to Russia and have it not even put in a dent. Yes, most of these weapons are outdated, but still very, very capable of inflicting serious damage on its neighbor.
