In Japan and South Korea there is deepening concern over the reliability of long-time American security guarantees – whether the U.S. will come to their aid in the event of a war. This has been turbo-charged by Donald Trump’s tough treatment of traditional U.S. allies, which has some in Tokyo and Seoul calling for a reassessment of their non-nuclear policies.
Well, France or the UK could also share their technology, or even Pakistan or India. I imagine it’s easier to buy the technology from an ally than developing it from scratch.
Eh. There’s nothing too crazy about developing from scratch. The hard part is generating your first batch of enriched uranium. A physics grad student could probably design a basic nuke. The US actually ran a test to that effect decades ago; a couple of physicists with no specialization in the nuclear side of things, and using only publicly available material, were able to design an implosion-type device. The expert consensus was that it would have worked just fine.
To get the uranium for the first bomb, you can always do what Israel did - have your spies literally steal it from US nuclear facilities.
Buying the blueprints would still remove the need for extensive testing, but you make a good point. After I posted the comment, I actually wondered about how hard it would be since there is so much information about nukes publicly available.
If you donated some money strategically you could probably get a copy of the US nuclear secrets to accidentally fall out of Mar-a-Lago’s bathroom window.
