What most people forget is that in a war the other party shoots back. It may take some time but it will happen and sometimes when you do not expect it. I think that Trump's move with banning Huawei is bad for the US in the mid and long run.
Yes, and these actions are the US finally shooting back after enduring years of industrial espionage, forced technology transfers, and market access restrictions.
The assertion that there's going to be consequences seems... inevitable? To me at least.
