But they're not doing investments that will entirely replace Taiwan's relevance. The bulk of their top tier technology will remain in Taiwan, and I would be very surprised to see that change. Moving some production to the US to alleviate worst-case scenarios for Washington, yes, but moving enough that Taiwan's defense becomes irrelevant? I really don't think so.

I mean, if you were TSMC's CEO/Board, knowing full well that your country of birth is highly dependent on your presence for its defense posture, would you do allow this to change?
