Good, Germany will continue as a center-point of the western alliance, and the CDU will stay centrist. Also this helps Merkel.
Because Germany suddenly would become an inward-looking, anti-EU illiberal regime if Merz had won amirite? Merz would have been more conservative on domestic issues (taxes, crime, immigration, etc), but Merz remains a part of the German political establishment. With a bit of creativity one could actually see Merz as the most globalist candidate lol (he definitely was the most Atlanticist candidate).
