Iran at the Breaking Point: How Afghanistan and Iraq Still Inform U.S. Strategy

EXPERT PERSPECTIVE — Iran is experiencing its most consequential period of internal unrest in years. Nationwide demonstrations driven by economic collapse, social grievance, and political frustration have been met with force, mass arrests, and near-total information control. The scale and coordination of the response suggest a regime that feels threatened but not unmoored, confident in its ability to absorb pressure while preventing fragmentation.This moment has reignited debate in Washington about escalation, leverage, and the possibility—explicit or implicit—of regime collapse. That debate is familiar. The United States has confronted similar moments before, most notably in Afghanistan and Iraq, where early assumptions about pressure, legitimacy, and endurance proved wrong.This article is not an argument for restraint or intervention. It is a warning drawn from experience: without understanding how competition unfolds below the level of open conflict – the gray zone – pressure alone does not produce favorable outcomes. Iran today sits at the center of a problem the United States has repeatedly misunderstood – not the use of force, but what comes before and after it.Afghanistan and Iraq: Where Strategy SlippedIn Afghanistan, the United States removed the Taliban from power quickly. In Iraq, Saddam Hussein’s regime collapsed even faster. In both cases, the decisive phase of the conflict ended early. What followed was the harder contest—one defined less by firepower and more by local power structures, informal authority, and external interference operating quietly and persistently.In Afghanistan, as I witnessed firsthand, regional actors adapted faster than Washington. Iran, Pakistan, Russia, and later China treated the conflict as a long game. They invested in relationships, cultivated influence, and positioned themselves for the post-U.S. environment years before the withdrawal. The result was not an immediate defeat on the battlefield, but a strategic hollowing-out of the state.Iraq followed a similar trajectory. Iranian-aligned militias embedded themselves within neighborhoods, religious institutions, and political parties. Over time, they became inseparable from the state itself. U.S. military dominance did not prevent this. In fact, it often obscured it, until the architecture of influence was already in place.The lesson from both cases is straightforward: control of territory is temporary; control of networks endures.Iran Is Not Afghanistan or Iraq — But the Pattern RhymesIran today is often discussed as if pressure will produce rapid political change. That assumption ignores how power is organized inside the Islamic Republic.Iran’s security model is deliberately social. The Basij is not simply a paramilitary force; it is embedded across society—universities, workplaces, neighborhoods, religious institutions. Its purpose is not only repression, but surveillance, mobilization, and ideological reinforcement. This structure was built to survive unrest, sanctions, and isolation.Externally, Iran has exported the same logic. In Iraq, allied militias function simultaneously as armed actors, political movements, and social providers. In Afghanistan, Iran preserved influence across regime changes, maintaining access to key actors even after the fall of the Republic. These are not improvisations; they are the product of decades of learning.It is worth remembering that Iran was not a spectator during the U.S. presence in Afghanistan and Iraq. It observed American methods up close—what worked, what failed, and where patience outperformed power. Tehran adapted accordingly.Why Escalation Without Preparation BackfiresMoments of internal unrest often create pressure for external action. Yet Afghanistan and Iraq show that collapse—real or perceived—creates its own risks.Removing a regime does not dismantle informal power structures. It often accelerates their consolidation. Networks that survive pressure are the ones that define what comes next. Iran’s internal system is designed precisely for this kind of stress: decentralized, redundant, and socially embedded.There is also a strategic paradox at play. External pressure can validate internal narratives of siege and foreign threat, strengthening coercive institutions rather than weakening them. Information controls, security mobilization, and proxy signaling are not reactions; they are rehearsed responses.This is why simplistic comparisons—whether to Eastern Europe, Latin America, or past protest movements, are misleading. Iran’s political ecosystem is closer to the environments the United States faced in Kabul and Baghdad than many in Washington are willing to admit.Who’s Reading this?

Economic distress, generational change, and legitimacy erosion are real. But history cautions against assuming that pressure equals control or that unrest equals opportunity.The more relevant question for U.S. policymakers is not whether Iran is vulnerable, but whether the United States is prepared to operate effectively in the space that follows vulnerability.That preparation requires understanding how authority is distributed beneath formal institutions, recognizing how coercive and social systems reinforce one another, and anticipating how regional actors adapt during periods of instability.These are the same lessons Afghanistan and Iraq offered lessons learned too late.Iran’s current unrest has reopened a familiar debate in Washington about pressure, leverage, and escalation. But Afghanistan and Iraq should have settled that debate long ago. The United States did not lose those conflicts because it lacked military power; it lost because it underestimated how authority, loyalty, and influence actually function inside contested societies.Iran is not a blank slate, nor is it a fragile state waiting to collapse under external strain. It is a system built to absorb pressure, manage unrest, and outlast moments of crisis. Any approach that treats unrest as an opportunity without first understanding what follows it risks repeating the same strategic error the United States has already made—twice.The choice facing U.S. policymakers is therefore not whether to act, but how to act without misunderstanding the terrain. Escalation without preparation does not produce control; it produces consequences that others are better positioned to manage. If Washington has truly learned from Afghanistan and Iraq, it will recognize that the most dangerous moment is not the collapse of order, but the false confidence that comes before it.History will not judge the United States on whether it applied pressure. It will judge whether it understood what that pressure would unleash.The Cipher Brief is committed to publishing a range of perspectives on national security issues submitted by deeply experienced national security professionals.
