I suppose visible is subjective. But they are also key component and raw material suppliers for essentially everything high value as well. The west simply does not have the heavy industrial or resource extraction base to account for anything else to be the case. Every time I’ve looked into literally any product China is at the start of the supply chain if lot much further into it.

And yes, I am alleging outright fraud and misrepresentation when it comes to stuff supposedly required to be entirely domestically sourced due to national security. If China froze all exports to the US and its allies, the US manufacturing base would simply cease to exist in rather short order. The China link might be 35 steps down the supply chain and buried 4 countries deep - but it’s almost always there.
