My point in the comment to which you responded is not that entirety of each constituent stage of the semiconductor production cycle belongs entirely to a different country. Rather, I contend that the lion's share of each constituent stage is maintained by a different country.

I agree that Korea has competitive processor designs. Of course, even Samsung uses many Qualcomm SoCs and licenses many Qualcomm patents. If you remove US-developed design IP entirely from the Samsung portfolio, how many Samsung products would be affected? I think many.
