Pre-WWII, what part of economy of Germany and Japan was

in US?

It was because their economy didn't mix much with US but at the same time, they were competing for resources, that was why US had no problem fighting with them. It is not the same with PRC and US now.

This is a most flawed reasoning for the this author. The others are passable but this essay wasn't written this year. It has some age to it already.
