No, it's impossible today for any country to do it all on their own. And even if you looked at the United States, which is still the biggest player in the supply chain by far, it's still the case that the U.S. can't do it all on its own. As you mentioned, it imports lithography equipment from other lens, it imports chemicals and materials from Japan, and then the most advanced fabrication of processor chips is in Taiwan. So no country can do it alone, and really no country is even close.
