Can U.S. Bases Leave the Gulf? Iran War Revives Old Questions About Security and Trust. Iran wants U.S. bases gone—but history suggests that demand may be impossible, for now.
The question of whether American military bases can leave the Gulf has resurfaced amid the Iran war—but history suggests the answer is far from simple.
To understand why those bases exist, analysts often look back to the Tanker War, when Iran targeted oil tankers and maritime routes during its conflict with Iraq. The escalation drew the United States directly into Gulf security, leading to naval escorts, clashes at sea, and ultimately the establishment of a permanent American military presence.
That presence was not theoretical—it was a response to a specific threat: the disruption of global energy flows.
Today’s crisis echoes that same pattern. Iran’s actions in the Strait of Hormuz—once again restricting maritime traffic and threatening energy exports—have reinforced the original logic behind U.S. bases in the region.
From Washington’s perspective, these installations are not simply strategic assets; they are deterrence infrastructure designed to prevent exactly the kind of escalation now unfolding.
Iran, however, sees it differently.
Tehran has reportedly demanded the removal of American forces as part of broader conditions tied to ending the war. In theory, such a demand aligns with its long-standing narrative that foreign military presence fuels instability rather than prevents it.
But in practice, the gap between those positions is defined by one word: trust.
The United States and its allies argue that any withdrawal would require verifiable and sustained changes in Iran’s military posture—particularly its missile programs, proxy networks, and ability to disrupt regional security. Without that, the risk of a power vacuum would be immediate.
That concern is not limited to the West.
Major Asian economies—including China, India, Japan, and South Korea—depend heavily on uninterrupted energy flows through the Gulf. As the current war has shown, any disruption in the strait quickly becomes a global economic crisis.
This raises a deeper question: if the United States were to step back, who would step in?
For now, no clear alternative security framework exists.
The war has also exposed a broader shift. Iran remains a significant regional military power, with capabilities built over decades—not just for defense, but for influence through allied groups across multiple countries. That network complicates any attempt to redefine security arrangements in the Gulf.
At the same time, Iran itself is not unchanged. Internally, it faces economic strain and generational discontent, raising questions about its long-term trajectory. But those internal pressures have not yet translated into a fundamental shift in external behavior.
That leaves the current reality intact.
American, British, and French bases in the Gulf are not there by default—they are there because of perceived risk. Removing them would require a transformation in that risk environment, not just a political agreement on paper.
Until then, the logic that created those bases in the 1980s continues to apply today.
The war may end. The tensions may ease.
But without a new foundation of trust, the infrastructure of deterrence is likely to remain.
