Gandalf’s judgment on Denethor as given in Lord of the Rings: The Third Age:
Thus is the havoc when a steward breaks his solemn bond with his people.
Gondor shunned counsel, chose to dominate its subjects. While its sons were sent to die in hopeless causes, alliances faltered. Hope withered. Armies were squandered, leaders lost.
Gondor became his, but such is not the role of the land’s steward. One does not rule. One leads, through love for the people, through foresight of the future.
In all of this Denethor failed.
Those who do not know the past are doomed to repeat it. Such will be history’s judgment on George W. Bush. Was Gandalf speaking of ancient times, or ours?
