analysis is reasonable for time being.  Until China comes up with her own semiconductor as you said, it can be quite risky to drag on any conflicts with Baboon Trump who can be unpreditable.  It will hurt many of us Americans too especially me. His declaration of Jerusalem as Israel's new Capital has shocked  many people.  No US president would go that far, but Trump.

I also read another article about US can win World War III withou having to use nucelar weapons against China or Russia.  I totally disagree though.  I think the guy exeggerated Americans' capabilities in this regards. Here is the link to it.
