Germany pretty much only ordered the F-35 to carry US nuclear weapons because their current platform (Tornado) is getting retired. They didn't want to hand over Typhoon schematics to retrofit it. They pretty much only had the choice between F18s or F35s.
You know, if we were really adversarial, it would be really really wise to reconsider allowing German planes, whether home built or bought from the US, "loaner" nuclear weapons to carry into battle.
