I'm pretty sure that some components of most us military equipment are made in china, or at least from metals imported from china. As much as I don't like china I think that almost every country in the world is dependant on Chinese manufacturing and mining .
If world would really be preparing to war with china we would see 20 years of building mines and factories in NATO countries. As for now wiping off china mean we are back to pre industrial times in terms of scarcity and price of everyday items.
Look through your kitchen, wardrobe etc. independent of which country you are in I bet at least half of things in there is "MADE IN CHINA" or "MADE IN PRC" and it's probably the cheaper half (with many few exceptions like maybe India)
