The defeat of Ariobarzanes (Ariobarzen) at the Persian Gates and the damage caused by modern Iranian collaborators with the US share the same core dynamic: a successful defense can be fatally undermined by a single act of internal betrayal. Both cases show how a well-prepared resistance can be reversed not through a direct military defeat, but through the exploitation of disloyalty from within, which has since become a recurring theme in Iran’s national security discourse.
The Historical Betrayal of Ariobarzanes
· The initial defense: In the winter of 330 BC, the Persian satrap Ariobarzanes, commanding a small force, successfully ambushed Alexander the Great’s army at the narrow Persian Gate pass, inflicting heavy casualties and blocking his advance toward the ceremonial capital of Persepolis.
· The act of treachery: After 30 days, the Persians were betrayed. A captured local tribal chief, sometimes referred to as a shepherd, revealed an alternate path through the mountains to the Macedonians. This allowed Alexander to outflank Ariobarzanes, leading to his defeat and death.
· The historical parallel: This event is often compared to the Greek betrayal at Thermopylae, illustrating how a secret path revealed by a local can turn a heroic stand into a devastating loss.
Modern “Treachery” in the Iran-US War
· Widespread espionage accusations: During the recent US-Israel conflict, Iranian authorities have repeatedly announced the arrest and execution of citizens accused of spying. In March 2026, the Intelligence Ministry reported arresting 111 “traitors” across 26 provinces who were allegedly plotting with Israeli intelligence.
· Direct collaboration in airstrikes: Iranian state media has broadcast footage of captured suspects who confessed to providing the US and Israel with crucial targeting coordinates and security information for their bombing campaigns. Other arrests have uncovered spies specifically trained to locate and share the positions of military depots and weapon caches.
· A persistent problem: This is not a new phenomenon. For decades, Iranian officials have warned about figures within Iran who are willing to collaborate with foreign powers. A 2025 editorial in a state-aligned newspaper specifically accused a network of self-exiled Iranians of advising the US on how to “harm Iran”.
Drawing the Parallel: A Tale of Two Treasons
The thematic link between these two events is unambiguous and is often used in Iranian political and historical discourse to underscore a key vulnerability:
· Defeat from within: In both cases, an external enemy, despite its superior military power, was unable to secure a quick victory. Alexander was effectively stalled for a month; the US and Israel have relied on bombing campaigns. In both eras, the decisive blow was delivered by a willing collaborator from the local population, not by the enemy’s army alone.
· The value of local knowledge: The shepherd and the modern spies provide the same essential service: revealing hidden vulnerabilities. The shepherd exposed a geographical secret, while today’s accused traitors expose military and security secrets, effectively acting as a “force multiplier” for Iran’s adversaries.
· A national security lesson: The story of Ariobarzanes is regularly invoked in Iranian cultural and educational contexts as a symbol of patriotic sacrifice betrayed by a cowardly insider. The modern arrests serve the same purpose, reinforcing the message that internal disloyalty is a critical threat that can undermine even the most determined national defense.
