I don't think you can blame both of these crises, or even either one of them, entirely on either the McDucks or Bradford. Magica and Lunaris both acted on their own will, and neither was compelled to act on anything that Scrooge or F.O.W.L. did. Sure, it's not like Magica was going to accept having her body trapped in the Number One Dime, but SHE is the one who pursued a feud with him in the first place.
True, but don’t forget Bradford Buzzard was the one who told Della about the Sphere of Selene lead up to the events involving Scrooge being isolated and the invasion even after Della came home.
@CosmoStar24 yes, but Bradford wasn't aware-presumably-that there was a civilization on the moon that Della would come in contact with. Nor was he responsible for the years/decades in which Lunaris and his father apparently regarded Earth and its inhabitants as something to be feared/hated.
I understand Bradford was unaware of Moonlanders or Lunaris’ true evil nature, but sometimes his and McDuck’s actions might have consequences whether they knew it or not.
