The Chip Wars book is an excellent read and tells you us the supply chain is globally integrated. If we were to draw a country graph of technology dependence to create semiconductor technology T (tools, chips, etc) - well, there is no DAG. The defense department is not so happy to see all this free market sharing of essential technology going on as it benefits non-friendly nation(s).
The book also illustrated how behind Russia was/is with weapons technology and semiconductors in general (compared to the US).
