Renowned author and journalist Stephen Kinzer has written a great deal about U.S. foreign policy and relations with other nations. He frequently addresses the difficulties of leadership and power shifts in different parts of the world in his writings.

Kinzer's observation regarding leaders is predicated on the notion that people who gain notoriety during war or revolution typically have traits like paranoia and ruthlessness that are necessary for success in those circumstances. These characteristics can enable them to successfully negotiate hazardous situations, make difficult choices, and defeat their enemies.

But these leaders encounter a new set of difficulties after they come to power. Society and many of their own people expect them to change from being ferocious fighters to statesmen who value harmony, collaboration, and understanding. For someone used to the brutality of war or revolution, this change necessitates that they embrace traits like humility, compromise, and tolerance, which can be challenging.

A fisherman attempting to catch two different kinds of fish with a single line is analogous to Kinzer's realization. Similar to how it would be difficult for a fisherman who is proficient at capturing large predatory fish to abruptly change tactics to successfully catch smaller, schooling fish, leaders who are successful in conflict frequently find it difficult to modify their strategies once peace is established.

This shift is challenging because the abilities that made these people effective combatants might not translate well to leadership and governance that fosters harmony and prosperity. The paradox is that even the most flexible leaders are expected to undergo a radical change in character—from being ruthless and paranoid to being tolerant, compromising, and humble.

Kinzer's observation highlights the inherent difficulties faced by individuals navigating through major historical transitions as well as the larger theme of leadership adaptation. It challenges readers to think about the nature of power, the traits that are valued in various settings, and the challenges that come with expecting leaders to fundamentally alter their style once they are in charge.
