Prince William, Prince Harry will remain civil at reunion but ‘reconciliation is a long way off,' experts say

Royal historian Robert Lacey said the Duke and Duchess of Sussex risk becoming irrelevant like the Duke and Duchess of Windsor if they don't work out their differences.

On Wednesday, royal historian Robert Lacey told The Associated Press the public shouldn’t expect a quick resolution between the princes because they are fighting over core beliefs. While William, 39, is defending the monarchy, Harry is defending his wife. "It’s a matter of love versus duty, with William standing for duty and the concept of the monarchy as he sees it," the author told the outlet. "And then from Harry’s point of view, love, loyalty to his wife. He is standing by her. These are very deeply rooted differences, so it would be facile to think that there can just be a click of the fingers."
