Agreed. Investing in local R&D and having at least enough production capacity to locally manufacture enough decent-quality devices for government use is essential for national security.

But it is also very expensive. The US and China can probably afford it, and I suppose the EU as a bloc can. But for anyone else the cost would be prohibitive. India is a top-five economy, and yet we have only been able to develop 130nm (!) chips locally. (Taiwan makes 5nm chips and China is now reaching 7nm.)

Perhaps a solution would be for many of the 'other' countries to band together. The blueprints could be open-sourced so all partners can trust each other. Whether something like this will work in today's political climate is of course another question.
