In "The Return of Marco Polo's World," Robert D. Kaplan emphasizes the importance of recognizing the limitations of one's own advantages when engaging in complex international situations. He cautions against pursuing endeavors that may seem appealing but are ultimately futile, likening them to chasing after ghosts. This serves as a reminder to remain pragmatic and avoid overextending oneself in scenarios where one's strengths may not provide meaningful leverage.

Kaplan's insights suggest a need for strategic caution, urging individuals and nations alike to avoid getting ensnared in conflicts or issues that do not align with their inherent capabilities. As global dynamics shift, it is crucial to maintain a clear understanding of when to intervene and when to retreat, thereby preserving one's resources and strategic interests for more advantageous situations.
