Timothy Snyder is an expert on European history. He taught for many years at Yale University and held a prestigious chair in European history. In 2025, he accepted a chair at the University of Toronto. His Substack blog is titled “Thinking About…” This important essay appeared in May 9. Nothing Snyder says here has changed.
He wrote:
The United States has just spent billions of dollars to lose a war that enriches its oligarchs, impoverishes the citizenry, sabotages its alliances, and strengthens its enemies. As justification for the self-destructive mindlessness, the White House gestures towards Jesus and genocide.
On April 20th I was asked to speak in New York about ethics and power. My thinking, which I expressed in a conversation at the Council on Foreign Relations, on this little video, and in the media, was that our utterly unethical war was also utterly self-destructive. The war, a catastrophe in itself, suggests the guiding principle of Trump foreign policy: superpower suicide. The term was since come into more general use, and readers have been asking me to spell it out.
Empires have risen and failed before, but to my knowledge no state has ever chosen to kill its own power, and succeeded with such rapidity.
It is hard to see this clearly. Even as we oppose individual Trump adventures, we hope that in some way they are based on some understanding of the national interest. They are not. To get the perspective we need to see the nature of this anti-strategic self-slaughter, it will help to consider thirteen traditional bases of state power.
1. Statehood. A superpower must, at a minimum, be a modern state. This means that it must be an arrangement that includes, via law and other institutions, a larger body of citizens within a common endeavor. There is no sign that the Trump administration regards the United States of America as a state. It treats the existence of the United States as a commercial opportunity for a select few people, American and otherwise.
2. National interest. Another minimal requirement of superpower would be a sense of why that power must be used. The Trump administration exhibits no interest in the good of the people. Theorists of international relations have differed as to how leaders understand national interests; we are intellectually unprepared, however, for a situation in which the leader simply does not care about either the state or the nation.
3. Succession. Again, for a state to maintain itself as a superpower, it must maintain itself over time. The basic requirement of such continuity is a succession principle, a means by which authority is transferred from some people to other people while institutions continue to function. In the United States, democracy enables succession. Historically, there are means of succession, for example by dynasty (or dynastic adoption, as in second-century Rome) or by the decision of a politburo, as in China or the USSR (in the US this would be a capitalist politburo, the sort of oligarchical coven that got us JD Vance). Getting from democracy to such different arrangements would end the American republic. Trump aspires to stay in power indefinitely, and says so. By putting the vote in question, he puts America in question, and thus American power.
4. Elites. For states to thrive and to accumulate and maintain power, the right people have to be in charge. There is no perfect means to achieve this, and there is the inevitable tension, as the Roman Stoics and others have noted, between the skills needed to rise to the top and those suited to serving some general interest. And those who rise to a position of authority will try to pass it on to their children; the Roman Catholic Church went to the extreme of insisting on priestly celibacy to block this tendency. Historically, powerful states seek ways to enable qualified people to serve in positions of authority, regardless of birth. Ancient China had an examination system. Napoleon established the principle of merit in both civilian and military life. The United States had a civil service that was the envy of the world as well as a military that was its most meritocratic institution. The Trump administration has chosen to disable the civil service and to purge the military command of people of quality. This process has been carried out by people who are themselves wildly unqualified to hold any sort of office, let along cabinet positions. To see where we are, we must understand that people such as Tulsi Gabbard, Kash Patel, and Pete Hegseth, about whom one might raise other objections, had no business accepting their nominations, since they lack any qualifications. The fact that such people could be considered, let alone appointed, is a marker of superpower suicide.
5. Education. In a deeper sense, a superpower must have a mechanism to refresh its society, and thus its politics and administration, by preparing its population to understand the challenges of the world. This administration has done the contrary. University students are forbidden to gather and to speak their minds; university administrations are threatened with retaliation if they allow their faculty to teach freely; libraries around the country, including in military academies, are purged of useful books; public education generally is replaced with scams whereby tax money is transferred from the poorer to the richer while schools themselves are starved; an unregulated internet is allowed and indeed encouraged to transform the public sphere into a realm of emotions and recriminations.
6. Science. The rise of great powers often involves an alliance between politics and science. The ancient Mesopotamians were astronomers whose systems of describing the heavens still mark our ways of thought; so were the Mayans. The Romans managed to operationalize Greek science to build, defend, and cure. The Renaissance was, by no coincidence, also the age of exploration. Modern imperial powers built state institutions to fund science and attract scientists; the United States from the 1940s was the outstanding example of this trend, and science (often as practiced by immigrants) was the most important basis of American superpower. Current American policy is to fund science on the basis of primitive ideological taboos, and to discourage young scientists from immigrating to the United States. Senior scientists are also leaving; a colleague in a central position in US science just told me that he is leaving the country in part because the overall environment is better in other places. It is also US policy to cast doubt on basic scientific observations, such as that of human-caused climate change.
7. Energy. Human groups that pioneer new forms of energy technology rise; those that do not fall. This might be the most profound truth of our history; a magnificent forthcoming bookdemonstrates the significance of energy transitions at the most profound level, that of the history of life on earth itself. Humans who mastered fire could consume more energy themselves. Humans who domesticated dogs could use their energy to hunt mammoths. Humans who domesticated plants could turn solar energy to their own purposes. Humans who understood weather and climate could turn wind energy to the purpose of exploration and conquest, as did the Vikings. The United States was established on the cusp of a transition to hydrocarbon energy: coal, oil, natural gas. These forms of energy are now becoming obsolete, not only in ecological but also in economic terms. And yet this administration has chosen to cancel America’s energy transition and subsidize technologies that have no future. This is superpower suicide in perhaps the most basic form. And nothing could benefit America’s chief rival, China, more than this choice.
8. Technology. It requires little effort to associate technology with the rise of great powers. Military achievement is associated intimately with innovation; from the spur to the machine gun, the causal relationship is not really contestable. While the United States spends gigantic amounts of money on weaponry, the Trump administration has chosen to focus on weapons from the past rather than of the future. Trump’s idea is battleships named after himself based on what he remembers of a movie. The plans for “Trump-class” battleships are a mixture of the fictional and the vulnerable, which does reflect the man. The notion is to invest untold amounts of money into a kind of weapon has been understood to be obsolete since 1943, and which if somehow built would be highly vulnerable to weapons other countries now have. This strategic atavism draws the United States away from national security in its most basic sense. The shape of modern warfare is revealed by the high-tech war between Russia and Ukraine, especially in Ukraine’s successful self-defense. The Trump administration chose to ignore the lessons of that war and to demean and defund America’s Ukrainian ally, to the detriment of American interests and American warfighting.
9. Diplomacy. This art, celebrated by great powers, has been trashed by the United States. It cannot be practiced without understanding other countries, as the most focused American diplomats have stressed (for example, Henry Kissinger, who can hardly be excused of softheartedness). It has rested, in the American and other cases, on the deliberate construction of a diplomatic corps where people train in languages and trade in knowledge. Under the Trump administration, the foreign service has been trashed. The principle of diplomacy, such as it is, is that other countries will do what we want because we are big and bad. This has not worked. The bizarre notion that the president can himself “make deals” is the sign of a religious cult; like most cults, its activity is the generation of ever more creative excuses for the lack of performance. There is no evidence that Trump knows how to negotiate, and abundant evidence that he does not: for example, defeat in trade wars with China; personal vulnerability to the preferences of Russian leaders, and the disaster of Iranian nuclear enrichment, of which Trump himself is the chief sponsor. In practice, critical negotiations, with Iran and elsewhere, have been put in the hands of two people, Steve Witkoff and Jared Kushner, with close personal relationships with the president and obvious economic stakes in the relevant conflicts. The diplomacy of the Huns was far more sophisticated than this. It is hard to overstate how primitive the current American approach is, and how much joy it brings to America’s enemies.
10. Alliances. Great powers have allies. To be sure, they might change these alliances rapidly for reasons of interest, as the East Roman (Byzantine) Empire famously did. The whole history of the Roman Empire, for that matter, was one of active diplomacy with neighboring barbarians (as the Romans saw matters); archaeology bears witness to the arrangements that were made. The history of modern European empires was also one considered alliances, as the architects of American superpower understood. Under the Trump administration, useful allies are mocked and marginalized for no reason other than personal whimsy and a sense of grievance. Because there is no sense of state or national interest, there can be no understanding that alliances are of service. Trump feels annoyed because he is losing a war and removes US troops from Germany; those troops are there to enable the United States to win wars. I personally cannot think of any other example in which the leaders of a great power behaved in this way, presumably because these kinds of choices are inconsistent with the maintenance of power. The United States now seems to be treating as “allies” middle eastern countries that have nothing to offer except their own interests in the use of American armed forces in their own region, permanent engagement in the disastrous politics of oil, and financial opportunities for people personally close to Trump.
11. The international system. Postwar America did something far more impressive than build a system of alliances; it essentially created a set of laws, rules, and norms that allowed American power to maintain itself and to expand. The European Union and NATO, so abused by the Trump people today, were indirect and direct results of American policies intelligently designed to maximize American trade and security interests. But the achievement was far broader than that, and indeed historically unprecedented: the construction of laws and conventions that kept one country in the center of the world. Today, the Trump people make themselves at the World Economic Forum, the Munich Security Conference and similar gatherings and complaining that the rules are against them — the exact opposite was the case, because America made the rules. In deliberately destroying its own international system, this American government is improving the position of its rivals China and Russia, who have been calling for exactly this to happen, but who lacked the ability to make it happen.
12. The idea of victory. A superpower wins in confrontations, at least some of the time. This administration loses again and again, and is seen to lose by others. Trump announced that his main weapon of influence would be tariffs, but then lost his trade war with China, leaving Beijing more powerful and more emboldened. The Russo-Ukrainian war is a curious case. It would serve the interests of the United States in prosperity and stability for Ukraine to win; but under Trump the United States has switched its policy to one of support for Ukraine to support for Russia. So it has lost in that way. But since the United States has made that pivot, Ukraine has performed ever better in the war, and Russia has performed worse. And so the United States, amazingly, has managed to be the loser in the same war a double sense: by failing to see its own interests, and then by failing to fail. The Iranian war is an obvious strategic defeat in every traditional sense; insofar as there were any American objectives, they were not achieved. Trump’s policies have left Iran with more enriched uranium in the hands of a more radical regime which holds new sources of economic power in the world. In the current situation, in which military options have been self-humiliatingly exhausted, the useful instruments would be those that involved communicating with the Iranian people or influencing Iranian society. Those institutions existed until very recently; they were willfully demolished, to great fanfare, in early 2026.
The United States is now governed by people who celebrate defeat in symbolic terms characteristic of states in disastrous decline. Consider Defense Secretary Hegseth’s description of the rescue of a US pilot as the resurrection of Jesus. The screaming blasphemy of this might distract us from its strategic helplessness. Christological images of this sort are used as propaganda to transform defeat in the real world into victory in some imaginary one. The US lost the war in Iran. Among other things it was not able to sustain an air campaign. The downing of a US fighter meant than an individual mission failed. It is happy news, of course, that the pilot survived. But the notion that this was a “literal miracle,” as Hegseth claimed, brings the United States, sadly, into the tradition of losers who use Jesus to claim to be winners. An historical example of this was Polish Romanticism, with its idea that the collapse of a republic (chiefly due to wealth inequality) made of Poland the “Christ of Nations.” Donald Trump’s own self-deification has to be seen in similar terms: a president who could assert power in this world would not have to claim that his real authority comes from another one. His fantasies of the total destruction of Iranian civilization are part of an apocalyptic panorama that is inconsistent with decent politics.
13. Finances. Though not the most interesting historical subject, budget disaster stands behind many of the most notable collapses of state power, ancient and modern. Under Trump our national debt now approaches $40 trillion. National debt is higher than GDP of the country for the first time since the end of the Second World War. That is a notable point of comparison: it is normal to run big deficits when facing the challenge of the scale of a world war. We are running huge deficits for an entirely different reason: because we decline to tax wealthy individuals and corporations. That is not an approach that is consistent with fighting and winning wars, nor with maintaining the social services that allow a modern society to function. More profoundly: it reflects an approach to politics — government as customer service to the very wealthy — that leads us from power to ethics.
The war can lead us to a diagnosis of superpower suicide. Wars cannot be won by people who have no idea what they are doing, because they have no frame of reference (such as the nation or the state) beyond their own feelings. They cannot be fought well when the wrong people are making the daily decisions and the wrong weapons are being deployed. They cannot be reasonably brought to an end when there is no practice of diplomacy and no notion of the value of alliances and no concern about corruption.
But even a strict focus on power will lead us back to justice. But just as the war is only a symptom of superpower suicide, so superpower suicide is only a symptom of a still deeper condition, the one that must be addressed.
Even if all we cared about were American power, we would have to ask ourselves how to undo the distortions of democracy and the drastic inequalities of that enabled world-historical levels of strategic buffoonery. After a year of Trump, we face a situation where reform and repair are not the relevant categories. And, in a certain sense, this is useful. The fact that we reached this point, the fact that just a year of Trump could bring superpower suicide, shows us that the prior status quo was unsustainable.
The systems that made the United States a superpower cannot be rebuilt as they were, nor should they be: they involved structural injustices that made the present attempt at self-annihilation possible. From where we stand now there are two ways forward: one is the self-induced downfall of the American republic; the other is to reconsider American ideals and to restructure American politics so as to bring the people greater power over a more just future.

For worse but also for better, as the Ukrainians have shown us, this is a time when civil society campaigns can contribute to general security.
