the problem is usually getting the fissile material.

as far as non-state actors go though, other types of WMD are probably more attainable. Aum Shinrikyo is probably the most infamous example where a cult manufactured multiple chemical weapons. https://en.wikipedia.org/wiki/Aum_Shinrikyo#Tokyo_subway_sar...

Yes and no. For terrorism purposes, the primary (more or less the same as a "Hiroshima"-level "A"-bomb) would surely more than suffice.

I'm sort of struggling to think why anyone other than a nation state (looking to prove itself worthy of a seat at various tables) would want to possess more bang than that.

Granted there are a few nations at or close to A-bomb tech whom we would definitely not want having its bigger brother. Iran and NK especially.

I feel like the Nth Country Experiment kind of invalidates the idea that it makes sense to worry so much about hiding all of this, though? That 3 fresh physics PhDs were able to design a working bomb in as many years without having subject matter expertise to me shows that shows that the sort of adversary that has the resources to build such a project will have access to the resources to design it, too.

More likely is that the obvious approach is also totally the right approach and anyone with the relevant education could easily come up with it themselves, but the US government still censors it out of security theatre.

The blog goes into detail about how releasing any wrong information or misinformation about a secret, still defines the bounds and brackets the real information, and allows eliminating possible options (as no agency would reveal the truth.)

If that was the case, an actor could go "this is obviously not the way to build this, lets move on" so in a way, you have sped up the development.

Just like saying, "We have 100,000 nukes" (a lie), everyone knows its a lie, which means we DO NOT have 100,000 nukes, as we wouldn't reveal the truth.

Enough of these little "misinformations" get released, the closer to the truth someone can get.

Or, there are 5 people doing this type of research across the world, 3 of them barely taking calls on iOS and the rest just finally managed to migrate from IRIX to Cygwin last year, and they are to take all necessary actions for operational security and talent acquisition.

I would ask you to elaborate, but I guess that'd be pointless

Or simply suboptimal.

Link? I can't find any images that articulate a nuclear warhead like the one in OP's link.
