If we were manufacturing everything in the United States, supply chains would still be disrupted because companies would be sending workers home, which is what they are doing already. No supply chain is safe in the event of a global pandemic.

One day there might be a pandemic which affects the West but not China, which would make outsourcing supply chains look pretty smart. You are drawing a general conclusion based on the circumstances of a single, rare event.

Besides, where is the suicide of the west here? The west has benefitted from this arrangement for decades. The west is better off with this arrangement than it would have been without it, and this pandemic would have happened anyway, and it would have disrupted supply chains anyway.

I have not yet seen any evidence that lack of western manufacturing capability has made this pandemic worse. However, there is a massive body of economic knowledge that tells us that exploiting comparative advantage increases wealth.
