Headquarters of North Amercan operations is not the same as the headquarters of the company. You are talking and acting as if they are.
The US operations can be impacted, what goes on between China and Russia can not be. Now whether or not they care about US operations is a different queston. Sanctions are not magically in place across the world just because they have a US office. I'm sorry but you have no idea how things work, so I'm going to peace out.
