It is said that post WW2, one big stabilizing factor of the world is that we globalized and created interdependence on the 6 continent supply chain. It was in part due to technology gains, cheap energy and resources to power that tech and the fear of creating enemies that could now potentially fight back with nukes. A truly existential threat. If we all lean on each other to some degree, it works out better for most folks.

And now we see that this is rapidly degrading over the last decade.

I think the belief was that if the west cutoff China, they would be left in the dark. Instead they have more than enough knowledge on how to make these things that it became a driving force to active decouple from the west.

Provided the other economic/demographic/political issues don't become a major problem to China, this will definitely be a large blunder.
