I really don't think any car manufacturer is strictly foreign or domestic. A lot of electrical parts and general parts used on domestic cars come from Mexico, Japan, Korea, ect... and a lot of foreign cars are built right here in the USA. I would consider the automotive industry a melting pot of ideas and technologies from many countries.
One other thing to consider is cheap labor, everyone wants to save money... and car manufacturers are no different, if they can get it for less, they will.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
