What happens
In the sixteenth year of the war, Athens sends a massive expedition to subdue the neutral island of Melos, a Spartan colony. Before hostilities, Athenian envoys engage in a stark dialogue with Melian leaders, arguing that might makes right and that submission is the only rational choice. The Melians appeal to justice, hope, and Spartan aid, but the Athenians dismiss these as futile. The Melians refuse to surrender, and the siege begins, leading to the eventual destruction of Melos.

Key passages
“the strong do what they can and the weak suffer what they must”
Those with power act according to their will, while the powerless are forced to endure the consequences.
This is the most famous line from the Melian Dialogue, encapsulating the realist view of international relations.
“Hope, danger's comforter, may be indulged in by those who have abundant resources”
Hope is a consolation only for those who can afford to take risks; for the weak, it is a dangerous delusion.
The Athenians warn the Melians that relying on hope without material strength leads to ruin.
“Of the gods we believe, and of men we know, that by a necessary law of their nature they rule wherever they can”
Both divine and human nature dictate that those with the power to dominate will do so.
The Athenians justify their imperialism as a universal and inevitable law of nature.
