She should have read up a little more on the saga of the Duke of Windsor. The royal family basically exiled him, and he was a former king. As nice as Harry might be, and as fond of him as they might be, he just doesn’t have that much juice in the Mountbatten clan.
He was a former king who decided to give it all up for an American divorcee. He and Wallis Simpson were great fans of Adolph Hitler; and, the political powers in London were keeping sensitive documents out of the daily "box" that the king/queen receive every day. They sent the two of them to the Bahamas to get them away from Hitler and put them someplace where they could not do any damage to the war effort.
