They can ask for Israel's assistance, they managed to (relatively) covertly develop nuclear weapons without a major power getting in their way.
Granted, the US president who was pushing the most for inspections of Israel's Dimona nuclear facility was JFK, who ended up no longer being a problem for them (how very convenient).
Yes in theory and that's Taiwan's best bet. But the US would never go along with that because guarding Taiwan's democracy is not the main objective even as it is the main talking point. The main objective is US interests, which are not served by nuclear proliferation or by losing Taiwan as either a bargaining chip to extract concessions, or a chess piece in a proxy war to weaken China, the main rival to US global dominance. Taiwan's value as a bargaining chip or as an acceptable battleground to both sides for a controlled conflict, is unfortunately greater than it's value as a democracy
Upvote on this just cause $100,000,000,000 is a ridiculous amount of money. The most advanced lithography machines that have even been advertised cost $380,000,000. Huge number of lithography machines for $100B. [1] And if you're not going for the completely most leading edge lithography, then the price drops incredibly rapidly. $150,000,000 or close rolloff.
Really, personal opinion, yet America and most countries on Earth, should probably be able to get lithography machines cheaper than $380,000,000. However, that's an argument for the lithography industry. At an average Taiwanese salary of $18,000 / yr (NT$50,000 / mnth) that's 21,000 labor years / machine. Even with amortized development that seems like a lot.
