Arrogance. No. It is very simple: Germany does not have the concept of "National Security" and does not act like that. Germany has many big pharmaceuticals in the country. But guess what: We Germans searched a solution in a European context. We tried to not only vaccinate all of us but also everyone around us. We are exporting the shots all over the world (Canada as an example is supplied by Germany and not by the US).
And that European bureaucracy (consider spending taxpayers money) is screwing things (once in a while) up, is not a new thing.
I would call it naive and not arrogant.
