The world basically lives in a monotechonlogy bubble. What you have others will have and what others have you will have and production can be eventually set up to almost everywhere when provided the capital and labor. Blocking anything or isolating anybody has become an impossibility and any move of blocking anything has no other effect other than introducing speed bumps or creating an alternative ecosystem of the same technology. US seems to live in this world of a last cold war when it was still possible to limit things and compete with having the better tech and forcing others to come to you to have access to it, but that world died when the iron curtain came down. Now it is never coming back up even if US tries to impose it around itself and Europe and other honorary western countries and even if it did US couldn't compete with its university STEM departments filled with Chinese and production outsourced to Asia.
