I would probably disagree on nuclear weapons: the lack of access to the latest semiconductors cannot wipe the humanity out, it merely retards the development of indigenous industries (other than semiconductor).

Huawei ban is a message to the Chinese government about explicit spying - and will probably get reversed pretty soon. You can spy, but don't make it so obvious.

Interestingly, I think these bans might have another, unintended, consequence: they might trigger acceleration of locally developed alternatives. We might see more of the Chinese-developed processors and IP in general in the future.

But I do agree that the sooner everyone plays nice, the better it is for everybody. The problem is that there are plenty of forces that benefit from chaos and suffering.
