Perhaps it's you who should think about it. If what you're threatening me with is no worse than what you're going to do anyway, your threat isn't much of one at all. The US is telling China "come to the negotiating table and discuss how I'm going to murder you or else I'm going to murder you"; how could anyone expect anything but Chinese resistance to that? What you're threatening China with if it adopts the strategy I proposed is a technological blockade - guess what, it's already under one anyway and it's about to get worse no matter what. This shifts the calculus and makes my strategy optimal.
How would you know? Are you privy to the details of the trade negotiation? As of now Huawei is still free to purchase components and services from US companies. The US merely put a card on the table. Whether or not it gets played depends on what the other side will reveal.
I wouldn't be so melodramatic about it.
