There is a perspective that I think will crystalize the nature of this: Try to have a device made without sourcing parts of China. Maybe an assembled PCB. Maybe it's a tool of some sort. You will find that this is impossible, or much more expensive/worse experience than sourcing from China. Now, imagine a scenario where China collapses. (In the broadest sense). Whether it's a war as you say, or any other scenario. Imagine this happens in a few decades, after we (The world) has committed to this path. We will have lost so much of the tools we build our civilization on, and it will take generations to get this tacit knowledge back. What's good: We (humanity) can build things cheaper, and higher quality than ever before, thanks to China's exquisite, vertically-integrated, and automated manufacturing capabilities. What's bad: We are putting our eggs in one basket.
