Just looking at what is happening in the US right now -- an astonishingly corrupt banana republic increasingly led by an insane Christian nationalist movement that bizarrely doesn't seem to understand a thing about Christ's teachings -- I have more faith in North Korea's management of nuclear weapons than the US.
Nuclear non-proliferation relied upon a global order where borders were fixed and there was in essence an international law and detente. Now we have an America openly musing about militarily taking countries and land as if it's just casual talk.
Yes, everyone should have nuclear weapons. And many of them should be pointed at US cities. The US is undeniably the most dangerous nation on Earth right now, and has lost any and all credibility as a rational player.
No country that holds nukes should be considered a pillar of morality. That's stupid beyond belief.
Now you can you argue the current US president is a fanatic if you want. But I do not see how adding more bombs to more countries reduces the odds of nuclear warfare in the future.
The current equilibrium has worked well enough. I do not see why we need to hand over nuclear weapons to countries currently embroiled in bloody civil wars.
Your argument to antiquity: “that's what all of the world thought for thousands of years”
Your argument to popularity: “probably 99% or more of people in the world think today”
Not that you’re trying to use those points in a cogent way. You heard “christian nationalist” and proceeded to attack a strawman of gender advantage, which has nothing to do with it. I gave you a salient example, and you went off with a half cocked opinion, conveniently sidestepping any further discussion of the actual implications.
Would Ukraine have been invaded if it had nukes? Unlikely.
Will trump invade Canada? The odds are >0%, so nukes are pretty good defense mechanism.
