I remember installing OpenSuse on my PC from a random magazine CD over 20 years ago. Back to square one I guess. But how exactly would choosing a European-based Linux distro be better than a US-based one in the event of a Transatlantic war?
The code is open. The distribution, the binaries, are built on Germany. Maybe Redhat could be forced to add something in the case of such kind of war, but a German company will be out of this.
