The Athenian dictum, “The strong do what they can and the suffer what they must,” remains a cornerstone of political realism, originating from the Melian Dialogue in Thucydides’ History of the Peloponnesian War. This principle suggests that in international relations, power—not justice or morality—dictates the outcomes for states, particularly when a smaller entity confronts a vastly superior force. Academic analysis confirms that this passage, recorded in Book 5, serves as a grim meditation on the inevitability of power imbalances rather than an endorsement of unbridled aggression.
According to scholars at the London School of Economics, the dialogue between the Athenians and the Melians in 416 BCE highlights the collapse of diplomacy when one side possesses overwhelming military dominance. Thucydides, an Athenian general and historian, documented this exchange to illustrate the strategic choices facing city-states during the Peloponnesian War. The text serves as a primary source for political scientists examining the concept of “realpolitik,” a framework where state interests take precedence over ethical considerations, as noted by the Encyclopedia Britannica.
The Historical Context of the Melian Dialogue
The event occurred during the 16th year of the Peloponnesian War, a protracted conflict between the Athenian Empire and the Peloponnesian League, led by Sparta. Melos, an island colony of Sparta, sought to remain neutral. However, Athens demanded that Melos join their empire and pay tribute. The historical record indicates that the Melians appealed to justice and the hope of Spartan intervention, while the Athenians countered with the necessity of imperial security.
The dialogue is frequently cited in modern international relations theory to explain how the international system operates in a state of anarchy, where no higher authority can protect a weaker state from a stronger one. Historians from the University of Cambridge have observed that Thucydides does not present the Athenian position as morally superior; rather, he frames it as a cold, calculated observation of how power dynamics inevitably function within a competitive international order.
Power, Necessity, and Realism
The phrase “suffer what they must” highlights the limitation of agency for the weaker party. In the Athenian view, the Melians were not being judged on their character or the rightness of their cause, but on their inability to resist a superior force. This perspective has influenced generations of thinkers, including those during the 20th-century development of classical realism in political science.
According to the Council on Foreign Relations, applying historical lessons from the Peloponnesian War to contemporary statecraft requires a nuanced understanding of how empires maintain influence. While the Athenian argument was grounded in the logic of necessity, the eventual outcome—the total destruction of the Melian population—demonstrated the catastrophic risks associated with such rigid power politics. The Melians refused to submit, and following a siege, the Athenians executed all adult men and enslaved the women and children, as documented in historical accounts of the Peloponnesian War.
Modern Interpretations and Academic Discourse
Contemporary scholars often debate whether Thucydides intended to warn against the dangers of hubris or simply to report the reality of his time. The “strong do what they can” is frequently invoked in business and economic policy discussions to describe market dominance, though its application remains controversial. In professional economic circles, the concept is often used to illustrate how market leaders can dictate terms to smaller competitors, effectively mirroring the power dynamics of ancient city-states.
The ongoing study of Thucydides continues at major institutions worldwide, with new translations and commentaries being released regularly to address the complexities of his Greek prose. Readers interested in the original text can access digitized versions through the Perseus Digital Library, which provides the original Greek alongside various English translations for scholarly review.
Key Observations on Political Power
- State Agency: The dialogue emphasizes that in the absence of a global governing body, states are left to rely on their own military and economic capacity.
- The Role of Necessity: Thucydides argues that what is called “necessity” is often a justification used by powerful states to expand their influence without moral restraint.
- The Cost of Resistance: The destruction of Melos serves as a historical case study on the consequences for smaller powers that choose to defy dominant empires.
- Realist Framework: The work remains a foundational text for understanding the “realist” school of international relations, which prioritizes survival and power over ideology.
As the global economic and political landscape continues to evolve, the lessons derived from the Melian Dialogue remain a frequent point of reference for policy analysts. Understanding these ancient dynamics provides a lens through which to view modern negotiations, trade disputes, and the exercise of soft and hard power on the world stage. Further analysis of these historical parallels can be found in upcoming academic journals and policy briefings scheduled for release later this year.
