I think this paragraph from the OP addresses that pretty well:
> One obvious takeaway from the paper: whoa, America is far more reliant on China than it thought. But actually this underplays the complexity. Think back to our Brandauer electrode. The chances are that it was made of metals which were originally refined in China (I’m guessing here, but given China is the world’s biggest metal refiner this is not implausible). Those metals were then shipped to the UK where they were turned into the micron-accurate electrodes I saw being turned out of the machines in Birmingham. Then they were shipped back to another factory, probably in China, where they were put inside a rear view mirror.
Now I'm not saying China's not capable of manufacturing that electrode, probably of the 45% not made by Brandauer some or all are from China anyway, but the point is it shows the kind of disruption it would cause to any country. Some like China less than others like the UK, sure, but still disruption. Globalisation isn't quite 'we all get everything from China now'.
