The fact that Taiwan Semiconductor (TSMC) and Samsung are building new plants in the US is directly related to the Trump/Navarro 'Build US/Buy US' policies. Yes, the reality of Red China's aggression is also part of it, as are all the other factors such as logistics, taxes, labor force, etc.
But these plants aren't being built in Europe, nor Africa, nor South America; not even in Canada.
They're in the USA.
Thank Trump and Navarro.
