Consider that Boeing once had no European rival.

Europe is bulding consensus on what technology sovereignty means. This is a self-interested statement within that discussion. At some point the EU will appoint at rapporteur to synthesise those viewports into a formal definition. The EC will use that to develop a programme of works which is satisfactory to the member states and other interested states.

The US is often lulled by the seemingly endless discursive nature of pan-European projects to think that they are not serious or effective. And then one day there is an Ariane or Airbus or Galileo.
