This tight global integration is why US sanctions policy is so disruptive. The US is asserting the right to tell European, Japanese, Korean and Taiwanese companies who they can do business with, based on those companies' connection to the US economy. Use of American-designed software, interactions with a US bank, engagement in dollar-denominated transactions, etc. can all put a company under American jurisdiction.

It will be interesting to see if European countries begin to try to push back against this policy. Imposition of American sanctions against Iran on European companies have already caused a good deal of consternation in Europe. But so far, the EU has been too fractured to do anything serious about it.
