I remember the story rather like this:
US: "you want to certify your fighter for nuclear devices"
Germany: "yes"
US: "ooh, that will be expensive and takes a loooong time. Don't you want to just buy our F35 instead?"
And germany basically did. With the implicit understanding, to buy a piece of nuclear protection with that. Well, all gone ... so there are really only some voices left, wanting to keep buying the expensive, potentially useless bricks.
