Lessons for America: The Gap Between Rhetoric and Action

#498 – Anthony Kaldellis: Roman Empire, Byzantine Empire, R… · Jun 30, 2026 History

The Eastern Roman Empire worked because its armies were genuinely doing what emperors said they were doing: protecting subjects. Most of the world no longer believes what American leaders say their foreign policy goals are. Machiavelli's lesson, applied to empires across 2,200 years: it's not enough to say you're governing for the people. You have to actually do it. The rhetoric only has power when the action backs it up.

The final chapter broadens from history to philosophy. Kaldellis distills the Eastern Roman Empire's lesson for modern governance: invest in institutions that work for the majority of your subjects, explain to them why they pay the cost, and think in terms of long-term success rather than short-term gain. He contrasts this with American foreign policy, where he argues the gap between stated goals ('spreading democracy,' 'feminist wars') and actual actions has become so large that most of the world no longer believes the rhetoric — a failure the Roman Empire, for most of its history, managed to avoid. He and Lex discuss Aristotle's advice to tyrants in The Politics: the best way to persuade subjects you're a legitimate benevolent king is to actually be one. The conversation then expands to human nature across time — Kaldellis aligns with Thucydides that humans are fundamentally consistent across eras, with culture setting the dials rather than rewriting human psychology — and to the phases of human civilization (hunter-gatherer, agricultural, industrial-technological), with Kaldellis suggesting we are in the third phase and uncertain about the fourth. He closes with measured optimism: the sheer amount of global misery is probably decreasing every year, and there's no reason to despair.

Why the Eastern Roman Empire Lasted: The Two-Part Answer

#498 – Anthony Kaldellis: Roman Empire, Byzantine Empire, R… · Jun 30, 2026 History

Two factors, and two alone, explain the Eastern Roman Empire's extraordinary resilience: first, authorities made an extraordinary effort to persuade subjects they were ruling on their behalf — and then actually did so. Second, the empire had a tightly unified Roman and Orthodox identity that made every alternative — rule by non-Romans or non-Christians — worse. No separatist movements, no peasant uprisings, no warlords carving out territory. Just subjects who preferred to stay.

The Missile Markup: How Iran Money Funded the Contras

Selects: Iran-Contra Affair: Shady in the 80s, Part 2 · Aug 8, 2026 History

The Pentagon sold missiles to the CIA for $3,700 each. The CIA sold them to Richard Secord at cost. Secord sold them to Iranian middleman Ghorbanifar for $10,000 each. Ghorbanifar charged Iran even more. The profit — including $3 million in interest in one Swiss account — was diverted directly to fund the Nicaraguan Contras.
