Russia attacked ukraine because they didn't. Iran got attacked because it didn't. North korea isnt attacked because they have. That's the moral of the story.
It's "make nukes first, ask questions later"
This seems analogous to the idea that every household should have guns if they want to be safe.
Going with your analogy, this would be the same as if police basically ignored all home invasion/trespassing laws such that the only houses that criminals entered were in fact those of undefended home owners. In this scenario, it would be demonstrated, by this policy, that yes home owners need to own guns to be safe.
To your point, if you don't want a world where it's safer for home owners to own guns, than you need to ensure there are policies in place to create a world where that was true. The lesson of Ukraine and Iran is that, if you don't have nuclear weapons, your sovereignty is always at the mercy of nations that do.
A world where every country needs nuclear weapons to remain sovereign is similarly undesirable (on a larger scale) to a country where every home needs to have guns to be safe. However we're on a path with nuclear weapons where that is unfortunately not the reality we are creating.
Turns out, making yourself a more dangerous target works to an extent.
But if law enforcement is not only not doing their job but actively threatening you: well, I guess 2A won this time.
What is "the police" on the level of countries? There is no majority that agrees that, e. g., the NATO can serve as the police. It feels like on this level, we live in an anarchy with only very few actors who don't really want to live together. So maybe nukes are an option, although I don't like it.
The differences are so extreme it's a waste of time to discuss the analogy further.
I think a part of the reason North Korea plays crazy is because they have to. If the US didn't think they'd push the big red button, then we'd invade them in a heart-beat. Mutually assured destruction only works when you believe the other guy will push the button. So you need the bomb and then you also need to make sure everybody thinks you're willing to actually use it.
Let's hope NATO doesn't get compromised, else I see 30 new nuclear programs starting soon.
We all hooray (well, some of us) the "good" countries having nukes, to bring peace and stability. But it only takes one funky election to get a crazy person in charge of such "good" nukes. And if you 10x the number of nuclear powers, that's 10x more shots at that.
Seoul is in artillery range of the border.
More recent events show that it doesn't matter. India-Pakistan endless fight.
And Ukraine. Imagine they had nukes in 2022 and russian army advances. Should they nuke russian cities? It would not stop troops and give them more motivation to fight, to revenge. Should they nuke russian troops? To many nukes need for such large frontline.
The only nuclear weapons Ukraine would need is enough to reliably ensure Moscow and St Petersburg cease existing.
Do you really think the US would trade Washington and New York for a chunk of Mexico?
How do you explain India vs Pakistan?
I mean israel gets attacked even though they have nukes, but some rockets are not the same as a regime-changing war
(Probably the risk to S. Korea, and the risk of pulling China into a war.)
Iraq also attacked an allegedly nuclear capable Israel without fear of a nuclear reprisal.
Please give dates, locations, and number of casualties. Iran has made many aggressive statements and funded and armed Palestinian resistance organizations, but actual conflict between Israel and Iran has been mostly clandestine and not officially acknowledged, with a few exceptions where Israel and the US unilaterally attack Iran.
Regarding guns: if you have easy access to weapons, everyone also has access, so the Nash equilibrium is "get a weapon". If weapons circulation is restricted, the Nash equilibrium is "don't waste your money on weapons".
If it wasn’t the US as the world’s leading power, but rather China, the list of countries forced to give up nuclear programs would be entirely different.
I’m not against trying to limit nuclear proliferation, but trying to paint it as some democratic legal process is naive.
The US loves to use the UN as cover for their own strategic goals, but happy to ignore the UN if it benefits them. Same with those talking nuclear non-proliferation.
However, we don't live in a reasonable world, so I suspect the first step will be, as much as I don't want it, World War III.
