Ariane is from the ESA, which is an organization under EU. The claim was that "EU is finally decoupling itself from the USA". My point is: the EU already has Ariane, for instance. It decoupled a long time ago.

I don't thin ESA builds Ariane or any production launchers for that manner - Arianespace does.

ESA is a separate entity to the EU.

(When the UK left the EU it was able to remain in ESA because of this separation.)
