What French? What do you not understand about nationality requiring a passport? Companies do not have passports. There are no American, French, British etc companies. You are buying leftist bilge if you imagine companies have a nationality. This company may or may not have any French people working for it.
In addition expropriation of private property is another leftist idea you seem to have adopted at least for this thread. This vacine is private property. It belongs to this company and the owners of this company. The US government has no right nor moral standing to put Marines at the gates and expropriate the private property of the owners of the company via extortion.
Finally, France was not attacked. What makes you think the French government wants to buy this stuff?
