The quote from Barbara W. Tuchman's "The March of Folly: From Troy to Vietnam" highlights the futility and danger of trying to impose despotism on a large, powerful nation. It underscores the idea that such efforts are bound to fail, suggesting that instead of clinging to a losing strategy, one should choose to retreat strategically while there is still an opportunity. This approach is based on the recognition of the limitations of power and the inevitable consequences of overreach.

Tuchman's reflection serves as a warning against the stubbornness that often accompanies attempts to control or dominate others. It emphasizes the need for pragmatism in leadership and the importance of recognizing when it's time to withdraw to avoid greater disaster. Ultimately, this call for a thoughtful retreat is a reminder of the lessons from history, where many have been doomed to failure by their unwillingness to reconsider their positions.
