Members of the Trump administration have been invoking the ancient Greek historian Thucydides to justify their 'might makes right' approach to foreign policy, but experts argue they are misinterpreting the deeper lessons about the perils of abusing power without legitimacy, as Athens did before its downfall.

Why it matters

The Trump administration's embrace of unilateral coercion and bullying of allies and rivals alike threatens to undermine the post-WWII international order that has underpinned decades of American global leadership and prosperity. Abandoning the norms of responsible stewardship of power risks isolating the US and erasing the distinction between American conduct and that of authoritarian rivals.

The details

The administration has drawn parallels between its actions, like the military intervention in Venezuela and unilateral tariffs, and the 'iron laws' of power politics described by Thucydides in his 'History of the Peloponnesian War.' But experts argue the administration is missing Thucydides' central warning about how Athens' shift from 'benevolent hegemony to malevolent empire' ultimately led to its ruin. The administration's 'relentless bullying' of allies and rivals alike, from Ukraine to Denmark, ignores how Athens' violation of Hellenic norms and transformation of consensual leadership into coercive empire provoked the very war it sought to avoid.

  • In January, the president cited the 'iron laws' of power in justifying the Venezuela operation.
  • On April 7, Trump warned Iran that 'a whole civilization will die tonight' if it does not capitulate to US might.
