Thucydidean Realism

Published online by Cambridge University Press:  26 October 2009

Extract

What does it mean to think like a Realist? The question is important in the study of international politics. According to a recent survey of the field, more than 90 per cent of the hypotheses tested by behaviourists in international politics were Realist in conception. A wider survey of the field taken in 1972 (which included those more historically inclined) identified the American Realist Hans Morgenthau as the leading scholar of international relations and his Politics Among Nations as the leading book. The overwhelming majority of other prominent postwar general theorists have worked inside the Realist tradition.

Hoffmann, Stanley, ‘An American Social Science: International Relations,’ Daedalus 1 (1977), p. 44Google Scholar, also defended a discontinuity thesis in the social scientific variant of international relations. But he placed the break at, not after, Morgenthau. Hoffmann noted Morgenthau's claim to have discovered a set of laws of power, which established a scientific field of endeavour that took root in postwar America in the new discipline of international relations.

The heterogeneity of the system means that the only shared trait among states is the mutual recognition of sovereignty and territory (Wight, , Power Politics, p. 106Google Scholar). This presupposes some similarity of culture. But it also allows for great diversity in that all else, including motivations, and methods of decision, can differ among states.

The structural determination depends, we need to add, on the systemic interaction being sufficiently intense to select very efficiently for appropriate behaviour, such as would be observed under the economist's model of perfect competition. See the valuable discussion in Keohane, , ‘Realism, Neorealism and the Study of World Polities’, pp. 171175.Google Scholar

14 Bipolarity (the economist's ‘bilateral monopoly’) may, however, strain against the assumption of perfect competition.

15 Neither of these genealogies is uncontroversial. There is a large and interesting literature offering competing interpretations of Hobbes and Rousseau and Machiavelli. Each interpretation has significant and diverse implications concerning the significance of their theories for international politics. In this paper, I propose to concentrate on the equally controversial interpretive debate concerning Thucydides.

18 Diodotus did speak deceptively. He seems to have misled the assembly into believing that only the local oligarchs were rebellious, when it appeared that many more were involved (see Connor, W. Robert, Thucydides (Princeton, 1984), pp. 8788Google Scholar). But we need not assume that his entire argument was deceptive, anymore than we need to agree that Cleon made a true case for just punishment. Diodotus specifically chose not to make a moralistic or legalistic argument, and his prudence led him to approve reprisals that were categorically neither moral nor legal.

19 Thucydides's own views on what constituted wise and prudent policy are stated most clearly in II: 65 where he praises Pericles and his policies. Under Pericles, Athens was ‘wisely led,’ ‘firmly guarded,’ ‘at its greatest.’ Pericles displayed ‘foresight’ and ‘integrity,’ unlike his successors many of whom were governed by ‘private ambition’ and were a party to numerous ‘mistakes’ such as the expedition to Sicily.

26 A second set of critics have conceded that Thucydides attempted a power oriented explanation but argue that Thucydides's explanation is simply historically incorrect. This was the charge made by Adcock, F. E. in ‘The Breakdown of the Thirty year Peace, 445–431’ in Bury, J. B., Cook, S. A. and Adcock, F. E. (eds.), The Cambridge Ancient History (New York, 1927), pp. 190191Google Scholar, ch. 7, and supported by Donald Kagan's revisionist history of the causes of the Peloponnesian War (Kagan, , Outbreak, pp. 373374Google Scholar). The crux of Kagan's revision was that the truest cause according to Realist explanation was clearly not true. Athen's power was not growing between the end of the First Peloponnesian War (446) and the diplomatic crises leading to the Second (435) (see Kagan, Outbreak ch. 19). The growth of Athenian power in the 450s would have justified a Spartan preventative war. The Peace of 446/5, however, settled the First War following Athenian losses that radically reduced its power and according to terms that were acceptable to both Athens and Sparta. The actual outbreak of the Second—Thucydides's war—was in 431. Athen's power did not increase between the two; so power cannot be used to explain the war or Sparta's fear. Athenian power in 431 probably did not match its power in the 450s, when its fleet fought in Egypt, it occupied its seafaring rival Megara, and it controlled most of central Greece (Boeotia). But Athens did improve its strategic position after the peace of 446—that is, after the defeat in the first war which saw the loss of each of those possessions. Thucydides may have exaggerated when he called 431 the high summer of Athenian power (I: 1), but in the preceding fourteen years, there is some evidence of real strategic advance on the part of Athens.

Athens, as de Romilly and more recently de Ste Croix have noted, consolidated its naval preeminence, establishing complete command of the Eastern Mediterranean. It shifted to a coherent imperial strategy by shedding its least defensible landed possessions while colonizing the more defensible island of Euboea. In 441–10, Athens crushed the strategically well-sited Byzantium and Samos (the single largest among its Delian ‘allies’) and thereby absorbed them as subordinate tribute-paying states. Athens thus completed the transformation of the hegemonic alliance of Greek states it had inherited from Sparta after the Persian War into a true maritime empire (arche) effectively controlled from the imperial center (Romilly, Jacqueline de, Thucydides and Athenian Imperialism, translated by Thody, Philip (New York, 1963), pp. 1920Google Scholar; Ste Croix, , Origins, pp. 60Google Scholar). In 437 it sent major colonial expeditions to the Black Sea shore (Sinope, and Nymphaeum in the Crimea). This enhanced its commercial presence in that important granary, which was now more secure than Boeotia had been, as long as Athens maintained naval predominance. Athens then secured its northern sea route by planting colonies and forts in Thrace (437–6). It stocked a war chest of 6,000 talents drawn from surplus tribute. And, in the prewar crisis, Athens added a defensive alliance with Corcyra, the second naval power of Greece.

38 No more than an economist would regard a single bankruptcy as evidence of the inefficiency of a market would a Structuralist regard a single defeat as evidence of the weakness of structural explanation. But when large though corrupted states are neither easily eliminated by competition nor socialized to rational security and instead have the sort of influence Athens—and before her Persia and after Sparta (very briefly)—have on the international system, then particular actors are shaping the system as much as the system is structuring actor outcomes.
