“What is dangerous is all the misplaced hype about it (trade war)”
There is a real risk of danger to the global economy, from a major financial/economic crash in China. China and Asian economies would be hardest hit, and Europe would take it harder than us, but almost everyone would feel some degree of slowing.
Note the USA. Our exports are only 1.5T/22T or 7% of GDP. Even if a "world wide global slowdown" of 10% were to happen, it would only reduce out GDP by tiny amount or 1/10 of 7% or .7% of GDP. This is not a catastrophe. Imports would be unaffected in a slowdown.
