"Take the steps I have suggested, and you will be remembered, in office or out, as one of the bravest and greatest Ministers for Magic we have ever known. Fail to act, and history will remember you as the man who stepped aside, and allowed Voldemort a second chance to destroy the world we have tried to rebuild!"

—Albus Dumbledore's warning to Fudge of how his actions of denial will make him go down in history as a disgrace
