Technically, conventional war is largely obsolete. As long as you do have a reliable and credible nuclear deterrent. Germany has long been in the very comfortable position to fool itself into deeming conventional war obsolete without having to maintain an own nuclear deterrent. With the USA finally having revealed itself to even the most servile transatlanticist as an utterly unreliable ally, (in fact, as more of the kind of “ally” commonly referred to as “enemy”) this illusion is falling apart.
