We are not going to go to war against China to protect Taiwan,or for any other reason.
If we did,they would shut down exports to the US,and where would we get our new toaster ovens,car parts,tools,etc,etc,etc from then?
They even go so far as to hire key employees and management people to move to China to live rent-free for 2 or 3 years under contract to teach the Chinese how to run put up a new plant in China,run the equipment,and manage the input and output. In other words,do everything THEY were doing back in the US before the Chinese bought up the plants.
Hell,they even house them in special apartment blocks with more room and nicer accommodations not available to the typical Chinese workers in their positions.
