The US is under constant "attack" 24/7/365, maybe not physical attacks with guns/tanks/cannons/missiles and such but more of Cyber, IP, Infrastructure type.
National Security involves much more than protecting one's Physical Borders, but IP Borders, Cyber Borders, Financial Borders and Infrastructure Borders as well.
It's well known that Advanced Technology Companies are prime targets for IP theft, and have been for a some time, even from so called "friends" (Remember the 1982 Hitiachi IBM technology theft case, which Hitachi pleaded guilty).
No Government could ever hope to develop the advanced chips we have at our fingertips today, they are far too complex and difficult for any government, even the prestigious DARPA were passed many decades ago in creating advanced CMOS semiconductor technology and general purpose processor chips. So governments are relying on commercial chips, often lots of them, to implement the various forms of "National Security" and protect all the various "Borders". Same goes for Advanced Technology companies which have their own internal structures to prevent IP leaks and theft, many with government "assistance".
Thanks for the detailed answer! It is very interesting to get an opinion, not from the biased media.
I understand the anxiety about cyber attacks. I am not a country, but my home router was attacked so often that I refused the real IP.
But as for technology. Weren't American companies themselves looking for more favorable conditions in Asia and moving production there, refusing to pay americans a large salary? After all, they acted according to market laws - chose more favorable conditions.
I'm sorry, I have a lot of questions. If you think it's possible, please respond. I really want to understand what's going on.
Why are modern chips so important? Was life bad in America 30 years ago without them?
Why is there a threat of losing their production in Asia? Is there a lot of stealing?
Why didn't you want go to Mexico, for example?
Why does this threaten national security, and not a separate commercial company? Especially the one who does not know how to manage risks and does not know how to play a competent, far-sighted game in the market. He does not know how to protect himself from theft.
Why doesn't this threaten, for example, the open core, which is licensed to be produced by anyone who wants to? One successful USA company did not want to depend on Intel anymore and chose an open core - created own M1 processor.
Why is the protection of their companies in China causing a negative reaction?
Why is it important to be at the top and own the world, and not live quietly, enjoying the successes of others and buying the products of others?
Once again, I'm sorry for the many naive questions.
If you answer, there will be more understanding in the world, which is necessary for all of us.
