You know that meme where the guys are in a circle and a guy says something, then a guy gives a big thumbs up and they ignore him? Imagine that group is the allies occupying just about all of German territory, and supporting the new nations they are building in the ashes, and the guy who says something is a small group who can “claim” they represent the previous government, but are frequently not even respected by the pockets of shattered resistance spawned by the rotting corpse of that government. Usually it is referred to as Debellatio. Their state had collapsed. No one really negotiated with them. They can call out “surrender” but the allies and the remaining hardliners did not care.
