They have different pressure means on France now, like what they did about Alstom which is a strategic company for France (they produce essential elements about nuclear plants, nuclear submarines for example) now in the US hand through General Electric.
Correct me if I'm wrong but GE bought the energy/grid part of the company, not the infrastructure/transportation part.
The turbines production is now under GE
France has a robust nationalization laws, btw.
If US becomes belligerent enough, Alstom may be taken away from GE.
