In contrast I'd put estimate the Japanese at something like 6-8 weeks

How would that work out with the need to refine enough weapons grade plutonium / uranium?

The time needed to gather/refine the materials is part of why my estimate is 6 - 8 weeks instead of 36 hours to a week.

Probably with Japan accepting design compromises to build a working nuke off of reactor-grade uranium- IIRC South Africa did that back in the day, and a shitty gun-type nuke is a lot better than nothing.

You can't build a deployable nuke out of reactor-grade uranium. Even for highly enriched uranium, you need tens of kilograms of it. Plutonium is much more efficient, which is why everyone who can uses it. A "shitty gun-type nuke" needs even more of the material than implosion type weapon since it's significantly less efficient at getting enough of the material to go critical before the whole thing blows up.

There was a scandal a while back that makes me uncomfortable about putting the United States of America on the list of countries that can make advanced hydrogen bombs.

I'd imagine the destructive power of any bombs our adversaries could field top out at Hiroshima, and mostly are “dirty bombs.”

For what that's worth, which ain't much.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
