1. We agree with much of the analysis in John Vasquez, "The Realist Paradigm and Degenerative vs. Progressive Research Programs: An Appraisal of Neotraditional Research on Waltz's Balancing Proposition," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 899-912. But we do not agree, among other things, that balancing behavior per se provides a strong test of realism or that realism is beyond redemption. On various criticisms, see also Francis Fukuyama, The End of History and the Last Man (New York: Free Press, 1992); Richard Ned Lebow and Thomas Risse-Kappen, eds., International Relations and the End of the Cold War (New York: Columbia University Press, 1995); and Paul W. Schroeder, "Historical Reality vs. Neorealist Theory," in Michael E. Brown, Sean M. Lynn-Jones, and Steven E. Miller, eds., The Perils of Anarchy: Contemporary Realism and International Security (Cambridge, Mass.: MIT Press, 1995), pp. 421-461; Peter J. Katzenstein, Robert O. Keohane, and Stephen D. Krasner, "International Organization and the Study of World Politics," International Organization, Vol. 52, No. 4 (Autumn 1998), pp. 670-674; and Benjamin Frankel, ed., Realism: Restatements and Renewal (London: Frank Cass, 1996), pp. xi-xii. For rejoinders, see Kenneth N. Waltz, "Evaluating Theories," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 913-918; Thomas J. Christensen and Jack Snyder, "Progressive Research and Degenerative Alliances," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 899-912; Colin Elman and Miriam Fendius Elman, "Correspondence: History vs. Neorealism: A Second Look," International Security, Vol. 20, No. 1 (Summer 1995), pp. 182-193; Elman and Elman, "Lakatos and Neorealism: A Reply to Vasquez," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 923-926; Randall L. Schweller, "New Realist Research on Alliances: Refining, not Refuting, Waltz's Balancing Proposition," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 927-930; and Stephen M. Walt, "The Progressive Power of Realism," American Political Science Review, Vol. 91, No. 4 (December 1997), pp. 931-935.
2. Giovanni Sartori, "Concept Misinformation in Comparative Politics," American Political Science Review, Vol. 64, No. 4 (December 1970), pp. 1033-1053. This is another way in which our critique differs from that of Vasquez, who has also charged that the realist paradigm is degenerating. Vasquez argues that "there is no falsification before the emergence of better theory," and that alternative paradigms do not exist. We demonstrate that they do. Vasquez, "The Realist Paradigm," p. 910.

5. Or a "basic theory," "research program," "school," or "approach." For similar usage, see Stephen Van Evera, cited in Benjamin Frankel, "Restating the Realist Case," in Frankel, Realism, p. xiii; and Walt, "The Progressive Power of Realism." We do not mean to imply more with the term "paradigm" than we state.

Weatherhead Center for International Affairs Working Paper Series (Cambridge, Mass.: Harvard University, 1998). There we also employ these standards to reject paradigmatic definitions of realism based...
