No, it was rhetorical for this post, I must have responded to the wrong sub-thread.
I am not in Trump's or Pompeo's head, so I can't assume, like you and others, what people are thinking (whether protectionist or not). Objectively, though, I think that anything that cuts the many tentacles of the CCP reaching across the world is a good thing, and that includes any and all Chinese corporations. Ideological wars nowadays are fought economically; you'd have to be stupid to financially enable those which will counter your own interests. This could be the motivation of the Federal government, or it could be because Trump had a bad day. We'll never know, but I'm not going to make rash assumptions like you.
You may disagree, and that's fine. The thing is, there are many areas in which American companies are not dominant - European ones are, and we happily buy and use their products. e.g., Nokia/Ericsson for 5G infrastructure being one example. We've cannibalized on our own auto industry over the years and gone full Japanese because Americans actively despise the quality of domestic cars (save for trucks). If blind protectionism were being exercised, it would be exercised across the board, including in those industries where China is not competitive. But somehow we've singled out China. I wonder why (/sarcasm/rhetorical).
It's easy to scream protectionism and there's a lot of sentiment that that is what's happening, but the thing is that China has thoroughly shown that it will use any leverage it gains to further it's interests abroad and in the US, and those interests are contrary to my beliefs in large part, the ideology of my country. What they do in their country is their business, but we're not obligated to enable it abroad and within our borders.
