As an outside observer, the US is a beacon of transparency on this topic. In Israel the topic is under strict military censorship. What little discussion is allowed has to periodically sprinkled with the incantation "according to foreign sources".

We don't even know if Israel has nuclear weapons. Most people think they they do, but it is neither confirmed nor denied by any official source.

Well I guess that latter point is my real question - what would happen if you took one of the diagrams and the associated descriptions from something like "Dark Sun" and simply built it - what would happen?

Are you hiring machinists to build it, or are you hiring some engineers and physicists to design a bomb based on that design. Building according to the plans - we can assume some important details are left out, or sabotaged so that it looks like it will work but it won't. However engineers and physicists can start with those plans and run calculations/simulations/tests to figure out what will go wrong and then figure…

What I meant was following the same kind of exercise described in the article but for an thermonuclear weapon rather than a fission device - excluding the primary component.

Knowledge is determined by official government sources now? We know they have the bomb, nothing in Middle Eastern geopolitics makes sense except in light of this fact. It's like a black hole that you can observe by how it bends the light of objects behind it. Politicians have to play a silly game of pretend around the whole thing but normal people don't.

That's not 100% true though, but for the most part it is. The moment Israel demonstrates that they do have the bomb; for instance by using one or exploding one for test purposes the perception of Israel would change and this in turn would cause a change in attitude towards Israel. It would also telegraph what kind of yields they have which would say a lot about their capabilities. They are clearly very much aware of this and that is the main reason for the 'refuse to confirm or deny'. Some things are more powerful when left to the imagination of the perceived enemies.

> Today, the fear is back: with al-Qaida resurgent, North Korea out of control, and nuclear rumours emanating from any number of "rogue states", North Korea indeed got the bomb three years after the article was written - the interesting question is what kept Iran? They didn't manage that feat in 20 years (thankfully, to add).

Relevance to AI - forget the pause, the cat is already out of the bag

AI does not require access to highly enriched Uranium or a plant to make it as well as various other highly controlled substances. AI materials can be copied across the internet with great ease, which does not hold for nuclear bombs either.

There is a reddit where people discuss technical details about nuclear weapons design, do simulations: /r/nuclearweapons

The funny thing is that 99% of public domain info regarding nuclear weapons design comes from US released documents.

For Russia/China warheads we basically have no documents, and even exterior pictures are extremely rare.

There's only so much you can do to keep an 80 year old technology developed with slide rules from being reverse engineered by a dedicated group of scientists with the benefit of 80 years of advancements in physics and access to a supercomputer (ie an iPhone).

in 2003 they didn't have access to an iphone, but the regular desktops were pretty good.

The article is written in 2003, but the two students did the research in the 60s. Not many desktops available at that time.

As the other commenter says - North Korea isn't connected to the internet in any meaningful way so it's impossible to cyber sabotage their gas centrifuges remotely. Without the correct type of uranium, you can't build an a-bomb.

Iran's centrifuges weren't connected either. However Stuxnet was indeed successful.

The right choice for Iran is to stay close enough to completion of a bomb that it's a very credible threat to stave off US regime change; while staying far enough away to not provoke Israel into a preemptive attack. So it's not a technology calculation, but a geo political one.
