The latest attacks on commercial shipping in the Strait of Hormuz and President Trump’s declaration that, in his view, the ceasefire with Iran is effectively over have revived a familiar debate in Washington: Why would Tehran risk undermining diplomacy at the very moment when reducing tensions could ease economic pressure and international isolation?
The conventional answer is that Iran is trying to negotiate while simultaneously increasing its leverage through regional escalation. That explanation contains some truth. But it overlooks a more fundamental question: What if Washington is analyzing the Islamic Republic through the wrong lens?
Most American discussions of Iran begin with foreign policy. They focus on nuclear negotiations, sanctions, military deterrence, proxy networks and regional power balances. These issues are undeniably important. Yet they often treat Tehran as though its external behavior were driven primarily by external calculations.
That assumption leaves out a critical part of the picture.
The Islamic Republic’s foreign policy cannot be fully understood without examining its domestic political logic. For more than four decades, the regime has relied not only on state institutions, but also on a permanent narrative of external threat. Hostility toward the United States has become more than a foreign-policy position. It has evolved into an organizing principle that reinforces the regime’s ideological identity, legitimizes its security apparatus and portrays domestic dissent as part of a broader confrontation with foreign enemies.
Seen from this perspective, confrontation serves purposes that extend well beyond the Middle East. It helps sustain the political environment on which the Islamic Republic has long depended.
This domestic dimension has become particularly significant following the widespread protests of January 2026 and the government’s violent crackdown. Regardless of how one interprets those events, they underscore that Iran’s leadership continues to view internal instability as a major security concern. Since then, the authorities have maintained an extensive security presence inside the country, including organizing nightly rallies, setting up checkpoints, heightened surveillance and other extraordinary security measures designed to prevent renewed unrest.
For outside observers, these developments may appear unrelated to Iran’s regional behavior.
For Tehran’s leadership, however, the connection may be much closer.
Governments facing serious internal pressures often seek to preserve political cohesion by invoking external threats. The Islamic Republic has long portrayed national security and regime security as virtually inseparable. Within that framework, regional confrontation reinforces domestic narratives of national emergency, justifies the continued mobilization of security institutions and reduces political space for dissent, organized or otherwise.
This does not mean that every regional action undertaken by Tehran is primarily motivated by domestic politics. Iran’s leaders also respond to genuine strategic concerns, military calculations and regional rivalries. But ignoring the regime’s internal political motives risks producing an incomplete understanding of its behavior.
This may also explain why diplomacy and escalation are not necessarily contradictory from Tehran’s perspective.
Many Western policymakers assume that negotiations and military pressure represent opposite directions. If diplomacy advances, escalation should decline. But for the Islamic Republic, these two approaches can operate simultaneously. Negotiations may relieve economic pressure, reduce international isolation or buy valuable time. At the same time, controlled regional tensions can preserve the atmosphere of external danger that strengthens the regime’s domestic security narrative.
What often appears contradictory from Washington may therefore appear entirely rational in Tehran.
This distinction carries important implications for American policy.
For decades, U.S. strategy has largely centered on sanctions, military deterrence and nuclear diplomacy. These tools are designed to influence Iran’s external behavior. Yet they do not necessarily address the domestic political calculations that frequently shape the regime’s strategic choices.
If the Islamic Republic views external confrontation as part of its internal survival strategy, then neither diplomacy nor military pressure alone is likely to explain – or consistently predict – its behavior.
The question facing Washington, therefore, is not simply why Tehran escalates while it continues to engage in diplomacy.
The more important question is whether a political system that has spent more than four decades defining itself through permanent confrontation, exceptional security measures and the constant mobilization of society against external enemies can adapt to genuine normalization.
Until American policymakers place the regime’s domestic political incentives alongside its geopolitical objectives, they are likely to continue viewing many of Tehran’s actions as irrational or self-defeating.
They are neither.
From the standpoint of regime survival, they may represent a coherent – if deeply troubling – political strategy.
