This article combines the work of two unpublished papers. The theoretical sections are derived from Christensen's “Chained Gangs and Passed Bucks: Waltz and Crisis Management Before the Two World Wars,“ Columbia University, December 1987. The case study material is based on Snyder's “Offense, Defense and Deterrence in the Twentieth Century,” a paper presented at the Conference on the Strategic Defense Initiative, University of Michigan, November 1986. We are grateful to Charles Glaser, Harold Jacobson, Robert Jervis, Stephen Krasner, Helen Milner, David Reppy, Cynthia Roberts, Randall Schweller, Stephen Van Evera, Stephen Walt, Deborah Yarsike, William Zimmerman, and an anonymous reviewer for comments on various earlier drafts. We also thank the Social Science Research Council and the MacArthur Foundation for Christensen's financial support and the Program in International Peace and Security Studies at the University of Michigan for sponsoring Snyder's original paper.

2. We feel no need to take a position on the epistemological debates surrounding Waltz's theory, spurred in particular by John Ruggie and Robert Cox. We are satisfied to accept Waltz's scheme as what Cox terms a “problem-solving theory.” For current purposes, we hope to improve its problem-solving utility rather than to address its deeper epistemological adequacy. See Keohane , Robert , ed., Neorealism and Its Critics ( New York : Columbia University Press , 1986 ), especially pp. 208 and 214 Google Scholar .

By “theory of foreign policy” we mean a theory whose dependent variable is the behavior of individual states rather than the properties of systems of states. It does not refer to a theory that explains all aspects of a state's foreign policy.

For a work that preceded the publication of Waltz's and Jervis's theories but made many similar points, see Quester , George , Offense and Defense in the International System ( New York : Wiley , 1977 ) Google Scholar , especially chap. 10 on alliance behavior in World War I.

6. In addition to the above-mentioned works by Van Evera, see Posen, Sources of Military Doctrine ; and Snyder , Jack , “Civil-Military Relations and the Cult of the Offensive, 1914 and 1984,” in Miller , , Military Strategy , pp. 139 ?40 Google Scholar . Levy points out that difficulties in measuring offensive and defensive advantage make such judgments problematic for social scientists as well as elusive for policymakers. See Levy , Jack S. , “ The Offensive/Defensive Balance of Military Technology ,” International Studies Quarterly 28 ( 06 1984 ), pp. 219 ?38 CrossRef Google Scholar .

7. By “determinate predictions” we mean that if all other factors (such as checkerboard geography) are held constant, then knowing the polarity of the system and the perceived offensedefense balance will theoretically suffice to predict the alliance behavior of states. Of course, in the real world, other factors having some effect on alliance behavior may not be held constant, making our predictions probabilistic rather than strictly “determinate.”

17. This is at least implicit in Waltz's , arguments about interdependence in his Theory of International Politics , pp. 143 ?46 Google Scholar , juxtaposed to his arguments about the relative invulnerabilityof the bipolar superpowers, p. 172. Note also Waltz's remarks about firms on p. 135: “Morethan any other factor, relative size determines the survival of firms. Firms that are large incomparison to most others in their field find many ways of taking care of themselves?of protecting themselves against other large firms.”

25. This distinction works only as a rough first cut. There were deterrence failure aspects tothe 1914 diplomacy. Conversely, even firm, early deterrent threats might not have deterred Hitler's aggression. For a recent corrective along these lines, see Lynn-Jones , Sean M. , “ Detenteand Deterrence: Anglo?German Relations, 1911?1914 ,” International Security 11 ( Fall 1986 ), pp. 121 ?50 CrossRef Google Scholar . Recent correctives, however, do not negate the main point. Even followers of Fritz Fischer accept that Germany did not want a world war but that it stumbled into it as a resultof misguided attempts to ensure German security.

This general predisposition to underestimate the feasibility of blitzkrieg may even have lasted past May 1940 and contributed to the false hope that Hitler would not attack in June 1941. Politburo member Andrei Zhdanov believed in 1940 that “Germanyis incapable of fighting on two fronts,” and even after the fall of France, he considered that Germany was too “bogged down” by the war with England to attack the Soviet Union. Foreign Minister Vyacheslav Molotov said in June 1941 that “only a fool would attack us.” see Ra'anan , Gavriel , International Policy Formation in the USSR ( Hamden, Conn. : Archon , 1983 ), p. 18 Google Scholar .
