Honestly, people are too overly frightened about all of this mess.

North Korea is about as big of a threat to the rest of the world as my 14 year old cousin. It's hard to take their idiot narcissist of a leader seriously because the guy has the emotional maturity of a kid and kids make poor leaders in a country. I say we should just do the entire world a favor and bomb them and be done with it. Every other first world country likely wants the kid tyrant gone and bombs are the most effective way of dealing with such a problem. If he tries to launch a nuke, nukes can be shot down.

I also don't think that nuclear wars are a threat because all humans value their own self interest above all else. If a nuclear war broke out it would threaten everything all humans (including those that are actually in power) hold dear. No human; especially not one who has the cunning and intelligence necessary to usurp a position of authority high enough to where they would have the power to launch a nuke would make such a decision because it would threaten their own self interest and position of authority.

So honestly, it's good for one's mental health to not worry about such things. I stopped paying attention to politics and I stopped thinking about the state that the world is in long ago and it was one of the more intelligent decisions I made in regard to my mental state. Overthinking things and pondering hypothetical "what ifs" accomplishes nothing and only brings those who do it more potential suffering.
