I find it hard to imagine that they weren’t before- to be honest.

Compared to AMD, Intel is distinctly a “US” corporation, outside of that image they have large R&D centre's in Israel.

US corporations that deal with the military very often have a similar setup.

Lots of talk about Intel running their own fabs is taken with a “National Security” mindset, and, isn't it the large “too big to fail” corporations that end up very close to government anyway, even if they are very removed from being the best? Oracle comes to mind.
