I think you're confusing the board of directors with the major managers as well as subsidiaries of a head company. Those remain tend to remain one nation. Stocks and accounting information of all international subsidiaries all reside in the head company that remain in one nation, even if they move their operations elsewhere, and many of them are in the US which provides the largest stock exchange and public offering in the world.

Although the US is a charitable country, doing good while doing bad does not negate one of the other.
