He's been telling me this, for years. It's not a secret. The information has been out there, for ages. I'm surprised that the administration didn't understand this.
If the US sees it as a threat and wants to do something it should maybe look to what China has done. Because tbh what Trump did re Tariffs is pretty close to "nothing" all things considered.
They won't though because as soon as you have someone saying "look, let's just put together a staged plan so that in, say, five years we'll produce X% more electronics domestically..." you'll have a Republican shrieking about "five year plans" and how the USA is becoming communist
