The First Gulf War

John Mearsheimer views the First Gulf War as a classic case of limited war managed with realism. He argues that expelling Iraq from Kuwait was a necessary act of power politics to prevent Saddam Hussein from dominating the regional oil supply, which fits his core belief that great powers must stop any single state from becoming a regional hegemon.
He strongly defends the Bush administration’s decision not to march on Baghdad in 1991. Pushing further, he contends, would have produced a costly and unpredictable occupation. The United States achieved its strategic goal by restoring the balance of power without getting pulled into Iraq’s internal politics.
His later writings use 1991 as a contrast to the 2003 invasion. The First Gulf War worked because it had a clear, limited objective and broad international support. The 2003 invasion failed because it abandoned that logic and chased regime change and regional transformation instead, destroying the local balance of power and handing Iran a strategic windfall.
Mearsheimer frames his work as a theoretical framework rather than a set of predictions, but his forecasting record sits at the center of his public identity. He points to his successes as evidence that the world follows the brutal logic of offensive realism. Critics argue his failures come from that same rigid adherence to theory.
His record has genuine hits. In a 2014 Foreign Affairs article, he warned that the West was leading Ukraine toward ruin. If NATO continued treating Ukraine as a Western bulwark on Russia’s border, he argued, Russia would wreck it rather than let it slip into the Western orbit. He did not name a date, but many see the current war as a structural vindication. In his 2001 book The Tragedy of Great Power Politics, he argued China could not rise peacefully and would seek regional hegemony while the United States worked to contain it. That competition has since hardened into trade wars, military buildup, and the pivot to Asia. He and Stephen Walt also opposed the 2003 Iraq invasion, correctly predicting it would destabilize the region and empower Iran. Earlier, in 1982, he argued the Soviet Union would not attack Western Europe because it lacked a blitzkrieg option that could guarantee a quick win, and the late Cold War proved him right.
His failures are real too. In Back to the Future, his 1990 article, he predicted the end of the Cold War would bring widespread instability to Europe and argued that Germany and Ukraine should acquire nuclear weapons to maintain the balance of power. Neither happened. Europe stayed largely peaceful and integrated for thirty years. Like most realists, he also missed the internal collapse of the Soviet Union, since his framework reads power from the outside in and tends to ignore the ideological rot that can bring a superpower down without a shot fired. And while he predicted conflict over Ukraine, he initially read Putin as a rational actor seeking a neutral buffer. Critics argue he misjudged the personalist and imperial ambitions that drove the 2022 march on Kyiv, which looked less like a limited wrecking operation and more like an attempted conquest.
His hit rate runs highest when he predicts conflict between great powers driven by geography and structural interests. It runs lowest when he predicts how states reorganize internally or when he dismisses the stabilizing weight of economic ties and international law. He would say his failed predictions are not wrong in logic but simply premature, that states are behaving irrationally and have not yet reached the conclusions his theory points toward.
Scholars have dissected Back to the Future for decades, often treating it as the clearest example of where structural realism meets its limits. Robert Keohane and Celeste Wallander argue that Mearsheimer’s focus on anarchy is a blunt instrument. Institutions like NATO and the EU are not temporary alliances assembled against a Soviet threat. They are sophisticated frameworks that reduce the very uncertainty Mearsheimer says produces war, by offering transparency, a forum for negotiation, and mechanisms that make security competition unnecessary. When the Soviet Union collapsed, Mearsheimer predicted NATO would dissolve. Instead, the alliance adapted to manage instability and mistrust from within the system rather than against an external enemy.
Stanley Hoffmann called the 1990 piece a caricature of neo-realism. He argued that Mearsheimer failed to see that for a modern state like Germany, economic influence is a far more useful tool than nuclear weapons. The suggestion that Germany should go nuclear ignored the historical and domestic trauma that makes such a move politically unthinkable. Mearsheimer treats states like billiard balls, critics say, assigning them no interior life, no culture, no memory.
More recent critiques, sharpened after 2022, focus on his dismissal of nationalism and domestic agency. Historians note that his description of Ukraine as a vast flat expanse used by invaders reduces a nation to a buffer zone and strips it of political will. Others point to a tension inside his framework: he claims realism rests on objective power, yet his defense of Russia’s behavior depends heavily on Russian perceptions of a NATO threat. If realism is truly objective, they ask, why should a declining Europe frighten a rational Russia at all?
The scholarly consensus respects Mearsheimer’s consistency but holds that his 1990 predictions failed because he underestimated how much states can value absolute gains like wealth over relative gains like military dominance, how durable institutions prove once their founding enemy disappears, and how powerfully domestic ideology and historical memory can override what theory marks as the rational path.
