Prof. John Mearsheimer: 250 Years of American Foreign Policy

How did the United States rise from a fragile collection of colonies to the dominant power in the international system, and what does that history reveal about today’s great-power competition with China and Russia?

In this conversation hosted by the University of Chicago Graham School, Prof. John J. Mearsheimer – one of the world’s leading scholars of international relations theory and author of The Tragedy of Great Power Politics – examines 250 years of American foreign policy. Beginning with the founding, he contrasts the United States’ liberal language of natural rights with the hard nationalism of a new state determined to secure its independence, expand across the continent, and keep rival powers out of the Western Hemisphere.

Environmental Performance Index 2026 (Yale)

2026 EPI Policymakers Summary

Harnessing advances in data, science, and technology, the 2026 Environmental Performance Index (EPI) provides a comprehensive assessment of sustainability worldwide. The 2026 EPI ranks 177 countries on 47 indicators across 12 issue categories spanning three policy objectives: Environmental Health, Ecosystem Vitality, and Climate Change. These indicators provide a gauge at a national scale of how close countries are to established environmental policy targets. The EPI offers a scorecard that highlights leaders and laggards in environmental performance and provides practical guidance for countries that aspire to move toward a sustainable future.

EPI indicators provide a way to spot problems, set targets, track trends, understand outcomes, and identify best policy practices. Going beyond the aggregate scores and drilling down into the data to analyze performance by issue category, policy objective, peer group, and country offers even greater value for policymakers. This granular view and comparative perspective can assist in understanding the determinants of environmental progress and in refining policy choices.

America at 250 (Foreign Policy)

Pep Montserrat illustration for Foreign Policy

“The Cold War and its aftermath made the United States into the world’s hegemon. It was a global empire in all but name, with alliances, interests, and preoccupations spread across the world,” historian Odd Arne Westad writes. “What is most curious about the current administration’s policies is that they do constitute a revolution of sorts, a symbolic rebellion against the world that the United States has created.”

Along with Westad’s analysis of the country’s changing role in the world, Foreign Policy has published several essays on U.S. history as America turns 250. Among other topics, the series examines how the United States has shaped the global environment through consumption and conservation, how a fundamental tension at its founding has influenced the country and its diplomacy since, and even the “making of the mafia.”

P.S. We’ve temporarily lifted the paywall. You can read the full collection of essays here, as well as any other article on ForeignPolicy.com.

America at 250 (The Economist)

Animated stars and stripes and the flaming torch of the statue of liberty

Why anyone would want to leave Britain is beyond us. But in 1776 the 13 colonies declared their own version of Brexit, only with muskets. Out of this act of youthful defia

America would go on to fascinate, inspire and occasionally exasperate The Economist, founded in 1843 to champion many of those same ideals: open markets, free societies and human progress. To mark the republic’s 250th birthday, we offer not fireworks but something far more British—a review. An arch, authoritative, occasionally patronising review.

Over seven chapters—one a month until July 4th—we’ll scroll through America’s triumphs and hypocrisies, booms and busts. We’ll track its progress and regress through words, maps, charts and gems from our archive. Our first American correspondent, “fat, fair and forty”, was ejected from a hotel in the 1840s for preaching free trade. (We hated tariffs then; we hate them now.) A century later, when introducing our first US section, we promised to convey “the breadth and colour of the canvas on which the American democracy is painting current history”. We aim to do the same here, hopefully without overindulging in metaphor.,,,,

…….

In the year this timeline begins, not long after America declared its independence, the future of the young country was in doubt. George Washington’s troops were retreating, his army close to collapse. “These are the times that try men’s souls,” wrote Thomas Paine. Yet Paine was not one for despair. “What we obtain too cheap, we esteem too lightly.” He believed deeply in the Enlightenment ideals on which the new republic rested, and wrote to stiffen America’s resolve at a moment of genuine peril. Washington is thought to have read the words aloud to his troops.

Two hundred and fifty years later, America is in need of another dose of Paine’s resolve. The country’s great liberal experiment is under strain. Politicians show little regard for many of the Enlightenment ideals the founders held dear. Americans themselves are bitterly divided, rarely agreeing on what ails the country, let alone the cures. History offers some consolation. The American experiment has faltered before—and recovered. Its story has been one of setbacks as well as renewal.

From the moment the framers set out, in the constitution’s opening sentence, “to form a more perfect Union”, the country has wrestled with its imperfections. In Philadelphia in 1787, just after the constitutional convention adjourned, an ageing Benjamin Franklin was asked, “What have we got, a republic or a monarchy?” His reply: “A republic, if you can keep it.” America’s liberal experiment remains incomplete and contested. Two and a half centuries on, Franklin’s challenge endures.
