Not to mention, the government backed pension/retirement funds of many European nations are at least partially invested in global securities indexes and more conservative US corporate bonds. Which means many countries technically own chunks of Ford. Also, surprise! European nations often sell their municipal bonds (to fund local projects) to American companies. Using Ford specifically as an example, I know someone who works for a local municipality in Finland and travels to Detroit every so often to sell their muni bonds to the US auto companies. TL;DR the global flow of capital is absurdly interconnected. Trying to "hurt" a nation by not buying their goods can just as easily hurt your own country.
