While I don't accept the way you've reframed the decision criteria, I can point out one US nuclear attack sub busting a few ships loaded with fuel and food for the PRC "would collapse in weeks." Which is relevant since we're discussing my claim of how "narrow" the PRC's economy is, not anything about the US.

The US economy is deeply dependent on the Chinese economy. It is a total fantasy to pretend that the Chinese economy can suffer without US economy suffering massively as well.

Again, what's your point in trying to change the topic of the discussion? You certain Xi is going to further trash his own economy merely to further hurt the US economy?

For that matter, I think your original proposition has been partly proven wrong, the traffic jams at West Coast ports have deprived the US of timely container deliveries from the PRC and Asia in general. Some high value low weight and volume stuff got through via air, but somehow we continued to operate a modern technological industrial civilization.

Supply chain shocks and an official Chinese ban on exports are very, very different scenarios.
