What I am saying is that if the US dissolved, similar to the Soviet Union in your example, there isn't anything technically preventing Germany from being able to take over the nukes.
Do you not see a difference in comparing post-USSR Ukraine with Germany while allied with the very much alive US? Hosting US military installations that house nuclear weapons is very different from hosting abandoned nuclear weapons of a state actor that no longer exists.
