How? From where? The middle east is the only place that can supply China. The US will frankly easily shut down all Chinese trade.
Will that save Taiwan? Probably not but it’ll cripple them badly for a long time
Sorry but you have no idea what you are suggesting.
The scope of which we DEPEND on Chinese products is staggering.
One more shut down of “non-essential” businesses for a couple months and the world will be left in peril just for basic necessities.
Our withdraw from Chinese dependency will have to be gradual. That is a simple fact.
