It's possible everywhere. It wasn't practical from an economic perspective.

I believe the author's position is that previously, one of the only considerations was, "how much will it cost." Or, "Does it make sense for us to invest in X fab?" Now there are other considerations beyond the economic and I'm certain you will begin to see not only fabs, but the full chain, in the EU and China. Probably sooner rather than later.

What does that mean for the different economic blocks?

What does that mean for tech in general?

What does that mean for global security?

Do we, (the US), have sufficient creativity to wargame all that out and get an idea of the future?

Etc

I think that's what the article is about.
