The Carthage Problem
When Rome finally salted the earth of Carthage in 146 BCE, destroying its greatest rival after three brutal wars, something unexpected happened to the victors. Rather than celebrating permanent security, Roman society began tearing itself apart with civil conflicts that would ultimately destroy the Republic. The senators who had spent generations united against the Carthaginian threat suddenly found themselves without a common enemy to blame for their problems or rally against in times of crisis.
This pattern—the identity vacuum that follows the destruction of a defining enemy—has repeated itself across twenty-five centuries of recorded history. Human psychology, unchanged since the Romans walked the earth, still requires an "other" to define the "us." When that other disappears, societies don't celebrate; they fracture.
The Cold War's Aftershock
Americans experienced this phenomenon firsthand after 1991. For nearly half a century, the Soviet Union had provided a clear organizing principle for American domestic and foreign policy. Every budget allocation, every social program, every military intervention could be justified or opposed through the lens of competing with Moscow. The threat was existential, omnipresent, and conveniently located on the other side of the world.
When the Berlin Wall fell and the USSR dissolved, Americans initially celebrated. But within a decade, the country was mired in culture wars, political polarization, and a desperate search for new enemies that could provide the same unifying focus. The "war on drugs" escalated. "Rogue states" multiplied. Eventually, terrorism filled the void, but never with the same comprehensive clarity that the Soviet threat had provided.

The same psychological mechanics that drove Roman senators to civil war after Carthage's destruction now manifest in American politics. Without a foreign adversary to focus collective anxiety, that energy turns inward, seeking domestic targets that can serve the same psychological function.
The Ottoman Echo
European history offers another instructive case study. For centuries, the Ottoman Empire served as Christianity's defining enemy, the force that unified otherwise fractious European kingdoms. The siege of Vienna, the Battle of Lepanto, the Crusades—these conflicts provided a shared identity that transcended national boundaries.
As Ottoman power waned through the 18th and 19th centuries, European unity dissolved with it. The continent descended into the nationalist conflicts that would culminate in two world wars. Without the Turkish threat to focus their energies outward, European powers turned their military and psychological apparatus against each other.
The pattern holds because the underlying psychology remains constant. Humans organize their social identity through opposition. Remove the opposition, and the organizing principle collapses.
The Substitute Enemy Cycle
What follows the death of a defining enemy follows a predictable sequence. First comes disorientation—a period where the society struggles to understand what it stands for rather than what it stands against. Rome experienced this as confusion about the Republic's purpose beyond conquest. America felt it as the "end of history" malaise of the 1990s.
Next arrives the substitute phase. Unable to function without an enemy, the society begins manufacturing new threats or elevating minor ones to existential status. Rome found new barbarian tribes to fight. Post-Cold War America discovered an endless supply of regional threats that somehow required the same military apparatus once aimed at Moscow.
Finally comes internal targeting. When external substitutes prove insufficiently threatening, the society turns its enemy-seeking apparatus inward. Roman senators began treating political opponents as existential threats to the Republic. Americans began viewing fellow citizens with opposing political views as traitors rather than opponents.
The Modern Manifestation
This ancient pattern explains much about contemporary American politics. The hyperpartisanship, the apocalyptic rhetoric, the treatment of policy disagreements as existential conflicts—all reflect a society still psychologically organized around enemy identification but lacking a clear external target.
Both political parties now function as substitute enemies for each other, fulfilling the psychological role once played by foreign adversaries. The intensity of domestic political conflict has risen precisely because it now serves the enemy-identification function that external threats once provided.
The Inevitability of Crisis
History suggests no easy escape from this pattern. Societies built around enemy identification cannot simply choose to organize themselves differently. The psychological infrastructure remains, seeking new targets when the old ones disappear.
Rome never solved the Carthage problem; the Republic collapsed into Empire, then Empire into fragments. Post-Ottoman Europe never found unity without a common enemy; it took two world wars and the Soviet threat to temporarily recreate continental cohesion.
The lesson embedded in twenty-five centuries of identical behavior is sobering: victory over a defining enemy is often more dangerous than the enemy itself. The dragon's death leaves the dragon-slayers without purpose, and a society without purpose inevitably turns its weapons on itself.
America's current political crisis reflects this eternal pattern. Until the country develops an organizing principle beyond opposition—or finds a new external enemy to focus its energies—the internal conflicts will continue escalating. History offers no examples of societies successfully navigating this transition. The psychology that demands an enemy to define the self has proven more durable than any particular political system designed to contain it.
