John Mearsheimer

Mearsheimer was born on December 14, 1947, in Brooklyn, New York.[1] His father, Thomas J. Mearsheimer, was a civil engineer, and his mother, Ruth M. Mearsheimer, was a homemaker.[1] He married Mary T. Cobb on June 14, 1970, and the couple has three children: Ann, Max, and Nicholas.[1]

His path to academic life ran through two branches of the U.S. military. He served in the U.S. Army from 1965 to 1970, graduating from the United States Military Academy at West Point in 1970, and then transferred to the U.S. Air Force, where he served until 1975 and attained the rank of captain.[1]

Mearsheimer earned an M.A. from the University of Southern California in 1974, a second M.A. from Cornell University in 1978, and a Ph.D. from Cornell in 1981.[1] He received the Clark Award for Distinguished Teaching at Cornell in 1977, an early signal of the teaching distinction he would later sustain.[1]

Before joining the University of Chicago's faculty, Mearsheimer held research positions at two prominent institutions: he was a research fellow at the Brookings Institution from 1979 to 1980 and a research associate at Harvard University's Center for International Affairs from 1980 to 1982.[1] He also spent the 1988–89 academic year working at the Council on Foreign Relations in New York.[5]

Mearsheimer joined the University of Chicago as an associate professor in 1982 and rose to hold the R. Wendell Harrison Distinguished Service Professorship.[1] He also served as co-director of the Program on International Security Policy there.[1] The University of Chicago awarded him the Quantrell Award for Distinguished Teaching in 1985, and he was selected as a Phi Beta Kappa visiting scholar for 1993–94, a designation that brought him to lecture at eight colleges and universities.[1]

Identified by analysts as a leading representative of the realist school in international relations, Mearsheimer is associated with the approach that seeks to base foreign policy on national interest rather than sentimental moral considerations or the influence of ethnic and commercial lobbies.[2] His scholarship has been published in academic journals including International Security and in popular outlets including The Atlantic Monthly, and he has contributed opinion pieces to The New York Times on subjects ranging from Bosnia and nuclear proliferation to U.S. policy toward India and the Arab-Israeli peace process.[1][5]

In 2003, Mearsheimer was elected to the American Academy of Arts and Sciences.[1]

Mearsheimer's scholarly reputation rests substantially on his formulation of offensive realism, a theory that distinguishes his thinking from the defensive realist tradition. Where defensive realists argue that states seek only sufficient security, Mearsheimer contends that, because states can never be completely certain of other states' intentions in an anarchic international system, great powers are impelled to seek opportunities to improve their relative power and security whenever possible.[1][6] The result is a world in which hegemony functions as the principal guarantee of a state's survival.[7]

His book Conventional Deterrence (1983) received the Edgar S. Furniss Jr. Prize.[5] It was followed by Liddell Hart and the Weight of History (1988), an analysis of the British military theorist Basil Liddell Hart.[1] His 1990 article "Back to the Future: Instability after the Cold War" extended his realist framework to the post–Cold War environment, arguing that the end of bipolarity would produce more conflict pairs and more opportunities for war.[6]

The fullest statement of his theory appeared in The Tragedy of Great Power Politics (2001), published by W. W. Norton.[1][7] The book analyzes the likelihood of armed conflict after the Cold War and argues that, in a world without an overarching governing authority, states pursue maximal power as their best available guarantee of security.[1][7] Its chapters address anarchy and the struggle for power, survival strategies, the choice between balancing and buck-passing, the causes of great-power war, and the trajectory of great-power competition in the twenty-first century.[7] The Tragedy of Great Power Politics received the Joseph Lepgold Book Prize.[1]

Mearsheimer later co-authored How States Think: The Rationality of Foreign Policy with Sebastian Rosato. A 2023 review of the book noted its argument that Vladimir Putin should be understood as a rational actor and that critics who invoked Russia's invasion of Ukraine as proof of irrationality misunderstood the authors' conception of rationality.[8] He also wrote the Foreign Affairs article "The Inevitable Rivalry: America, China, and the Tragedy of Great-Power Politics," which warned that U.S. engagement with China had enabled the rise of a peer competitor and that Washington had failed to contain China's growth early enough, and argued that containment was the United States' only realistic means of preventing Chinese regional hegemony.[9]

On March 23, 2006, the London Review of Books published "The Israel Lobby" by John Mearsheimer and Harvard political scientist Stephen M. Walt.[3] A longer scholarly version containing more than 200 footnotes was posted as a working paper on the website of Harvard's Kennedy School of Government.[3] The publication quickly drew criticism from former policymakers, historians, academics, and Jewish organizations.[4]

The paper's central argument was that neither strategic nor moral considerations adequately explained the scale and consistency of U.S. support for Israel, and that the influence of a pro-Israel lobby was the principal explanation.[10] Mearsheimer and Walt defined "the Israel Lobby" not as a monolithic or centrally directed movement but as a broad coalition of individuals and organizations actively working to shape U.S. foreign policy in a pro-Israel direction.[11] They argued that this coalition had decisively shaped roughly thirty years of U.S. Middle East policy, particularly including the 2003 decision to invade Iraq.[3]

The paper attributed the promotion of the Iraq War partly to pro-Israel officials in the George W. Bush administration, specifically naming Paul Wolfowitz, Douglas Feith, and David Wurmser.[12] It further contended that the United States would not have been as focused on Iran, Iraq, and Syria without its close alignment with Israel, and argued that this alignment complicated America's international standing and its capacity to counter terrorism.[12] Mearsheimer and Walt also argued that U.S. support for Israel exacerbated anti-Americanism in Europe and the Middle East, and that pro-Israel views dominated media, think tanks, and universities, with accusations of antisemitism effectively discouraging open criticism.[13]

Mearsheimer and Walt defended their thesis and expanded the paper into a full-length book, The Israel Lobby and U.S. Foreign Policy, published by Farrar, Straus and Giroux in 2007.[11] The book's catalog description records the authors' argument that U.S. material and diplomatic support for Israel cannot be fully explained by strategic or moral considerations and is due largely to the lobby's influence.[11] Its chapters addressed the lobby's role in shaping U.S. policy toward the Palestinians, Iraq, Syria, Iran, and the Second Lebanon War.[14] The authors also argued, according to the book's description, that the lobby had affected U.S. relations with important allies and had increased dangers associated with global jihadist terrorism.[11] The book was published while Mearsheimer held his chair at the University of Chicago and Walt held his professorship at Harvard's John F. Kennedy School of Government.[11]

The authors presented figures arguing that Israel had been the largest annual recipient of direct U.S. military and economic aid since 1976 and the largest cumulative recipient since World War II, citing more than $140 billion in direct U.S. aid measured in 2003 dollars and approximately $3 billion in annual direct external assistance, and asserting that the United States had vetoed 32 U.N. Security Council resolutions critical of Israel since 1982.[5] These figures and causal claims formed part of a politically contested argument.

The publication of The Israel Lobby and U.S. Foreign Policy prompted responses from a wide range of former policymakers, historians, academics, and Jewish organizations.[4] The reception was sharply divided. One reviewer, noted in the Encyclopedia.com account, said the authors were serious scholars who were neither antisemites nor racists; another reviewer in the same summary criticized the book as unbalanced and overly reliant on one-sided accounts.[1]

Former Secretary of State George Shultz offered a direct counterargument: U.S. support for Israel reflected broad agreement among both political parties, national leaders, and the American public rather than the hidden hand of a lobby.[15] An Israeli government publication noted that polls showed more than 70 percent of Americans favored robust ties with Israel, presenting this broad public support as the reason the pro-Israel lobby is politically influential rather than as evidence that it overrides American interests.[15] In a 2008 Republican presidential debate, Israel was mentioned 18 times, compared with one mention of Russia and three of China—a figure the same publication cited to illustrate organic American interest in Israel beyond any lobbying pressure.[15]

Critics argued that the Mearsheimer-Walt thesis was not grounded in a careful investigation of declassified U.S. State Department, Defense Department, military, or intelligence documents.[10] Scholars and analysts disputed their characterization of the Israeli-Palestinian conflict, the Palestinian refugee issue, the Camp David negotiations, and U.S. policy toward Iran, arguing that the framework attributed major developments to Israeli influence while omitting competing historical explanations and later Israeli concessions at Taba.[16]

Steven Bayme characterized the Mearsheimer-Walt position as an example of defection by some sectors of elite opinion from the bipartisan pro-Israel consensus, while also noting that their claim that the lobby had hijacked American foreign policy failed to gain significant resonance in political campaigns or among voters, even as he acknowledged their views had some resonance within security and intelligence circles.[17][13] Adam Kirsch, as reported by the Times of Israel, offered an opposing assessment: even if their central thesis was rejected by mainstream and Jewish thinkers and media, the book had nonetheless affected public discourse about Israel and Jewish power.[18]

A Times of Israel report noted that, five years after publication, mainstream and Jewish thinkers and media had vociferously rejected the book's thesis that an "all-powerful Israel lobby" controlled American foreign policy.[18] Efraim Sicher described the book as having "canonized" the conviction that the Israel lobby exercised undue influence in the United States and recorded that the argument became part of wider British and American debates over whether pro-Israel lobbying exerted excessive influence over national policy.[19] Kenneth S. Stern distinguished criticism of U.S. support for Israel from what he regarded as antisemitic implications in parts of the paper, and also criticized its scholarship and its characterization of Israel as a strategic liability.[20]

Beyond the Israel Lobby controversy, Mearsheimer applied his offensive realist framework to several other major international questions. In his Foreign Affairs essay on the U.S.-China relationship, he warned that American engagement policy had allowed China to emerge as a genuine peer competitor and that Washington had not acted early enough to contain China's rise; he argued that containment remained the United States' only viable strategy for preventing Chinese regional hegemony.[9]

On Russia and Ukraine, Mearsheimer delivered a 2015 talk titled "The Primrose Path: Why Ukraine is the West's Fault," in which he assessed the causes of the Ukraine crisis, the best way to end it, and its consequences for the principal actors, emphasizing that accurately assigning responsibility for the crisis was necessary to formulate sound policy.[21] His co-authored book How States Think: The Rationality of Foreign Policy extended this analysis, arguing that Vladimir Putin should be understood as a rational actor and that dismissing him as irrational reflected a misunderstanding of how rationality functions in interstate behavior.[8]

On Iran, CAMERA reported that Mearsheimer stated during a PBS NewsHour appearance that "a nuclear-armed Iran would bring stability to the region" and that Iran had "hardly any offensive capability at all."[22] These statements were reported in a critical account by the media-monitoring organization rather than in a transcript supplied by Mearsheimer himself.[22]

The most sustained controversy surrounding Mearsheimer concerns his thesis—developed with Stephen Walt—that the Israel lobby substantially determines U.S. Middle East policy. The Anti-Defamation League characterized the work as conspiratorial and as invoking claims of Jewish power and Jewish control, arguing that its loosely and inconsistently defined concept of an "Israel lobby" was used to attribute U.S. policy to pressure designed to serve Israel's interests at the expense of American ones.[16][16] The ADL responded to the book by stating it gave credibility to accusations that were "little more than paranoid fantasies that reinforce persistent, anti-Semitic myths."[18] Kenneth Stern distinguished between legitimate criticism of U.S. support for Israel and what he considered antisemitic implications in certain passages of the original paper.[20]

In a 2010 lecture, Mearsheimer divided American Jews concerned with Israel into categories he called "righteous Jews" and "new Afrikaners," and stated that Palestinians were "not going to get their own state any time soon" and would instead live in "an apartheid state dominated by Israeli Jews."[9] These remarks generated significant criticism.

A separate controversy arose when Mearsheimer endorsed Gilad Atzmon's book The Wandering Who: A Study of Jewish Identity Politics, describing it as "a fascinating and provocative book on Jewish identity in the modern world."[23] Critics noted that the Atzmon book's associated language characterized Zionism as "blind loyalty to Israel" and referred to Holocaust warnings as "scaremongering," and presented Mearsheimer's endorsement as evidence of a serious lapse in judgment regarding Jewish identity and Israel.[23]

Mearsheimer and Walt also wrote that European Muslim antisemitism could be partly provoked by Israel's conduct toward Palestinians, while acknowledging that some of it was straightforwardly racist.[24] This formulation became a further point of criticism in assessments of their treatment of antisemitism. Taken together, these episodes produced a body of criticism from pro-Israel organizations, Jewish communal institutions, and academic commentators who argued that Mearsheimer's scholarship on Israel and Jewish political influence crossed the line from legitimate policy analysis into territory that legitimized harmful stereotypes.
