The EU is largely a freeloader when it comes to tech things and it seems like it cannot succeed in that field largely because of the EU bureaucracy (try to standardize things before they even started).
I think it's about time the EU starts to worrying about that, because it is no good to be so dependent on another country for something so critical.

And in any case, this is typical Trumpian bluster. Possibly the aim is to make independence happen because that would suit the US.
