Does Europe has the capability to make a stealth AC

I read on the internet a statement of certain American Official that Europe undertand the “theoretical” aspect of the stealth pretty well (ie. algorithms that calculate/predict the RCS of a given geometrical structure), however, what it lacks is the capability to make the the structure of the stealth with sufficient precision and tolerances.

This is quite surprising, since Germany and France are fairly advanced in matallurgy and making highly precise parts. Especially Germany I believe is a world leader in science of mechanical engineering.
