Iranian missile and drone attacks have exposed deep vulnerabilities in the United States military’s long-established network of bases across the Persian Gulf, raising the possibility that Washington could permanently reduce its regional footprint and shift significant forces farther west.
The warning came from retired four-star U.S. Army General Barry McCaffrey, who said he believes the United States has “probably permanently lost access to 15 Persian Gulf bases.” McCaffrey, now a national security analyst for MS NOW, said Iran could increasingly influence American access to Gulf states and that Washington would need to negotiate alternative arrangements in western Saudi Arabia, Israel and southern Europe.
His assessment is not a formal Pentagon determination. There has been no public announcement that 15 U.S. bases have been permanently abandoned, nor has Washington announced a comprehensive restructuring of its Middle East force posture.
But the assessment comes as U.S. officials and military planners examine whether heavily damaged Gulf installations should be rebuilt at their previous scale or replaced with a more dispersed network of smaller, harder-to-target facilities.
The Financial Times reported that the future of major American bases in the Gulf is under serious reconsideration following extensive damage caused by Iranian missile and drone attacks during the conflict. The newspaper reported that repairing damaged facilities could cost about $5 billion, while U.S. planners are considering more mobile and distributed alternatives.
The debate could become one of the most consequential changes to the American military posture in the Middle East in decades.
For years, the United States has relied on a network of bases stretching from Kuwait and Bahrain to Qatar, the United Arab Emirates, Saudi Arabia and Oman.
The network provides the infrastructure needed to conduct air operations, support naval forces, store equipment, maintain aircraft, move personnel and supplies, gather intelligence and coordinate operations across the Middle East.
Among its most important locations is Naval Support Activity Bahrain, home to the headquarters of the U.S. Fifth Fleet. Qatar’s Al Udeid Air Base has also served as a major regional air-power and command hub, while Kuwait has provided critical logistics and ground-force infrastructure.
The architecture offered Washington a major strategic advantage: American forces could operate close to potential flashpoints without having to move personnel and equipment thousands of miles from Europe or the Indian Ocean.
Iran’s missile and drone campaign, however, demonstrated the vulnerability inherent in that geography.
Many of the installations are relatively close to Iran and contain large concentrations of aircraft, fuel, ammunition, communications systems, maintenance equipment and personnel.
That concentration makes them attractive targets.
Iran does not need to destroy every American aircraft or ship to impose substantial military costs. Damaging a runway, fuel storage facility, radar, communications node or maintenance complex can temporarily reduce the effectiveness of dozens of combat platforms.
The result is a shift in the definition of the battlefield.
Rear-area infrastructure that once operated largely as a protected foundation for U.S. combat power has increasingly become part of the contested battlespace.
The central strategic question for Washington is therefore not simply whether American forces remain militarily superior to Iran.
They do.
The question is whether that superiority can be generated and sustained from bases that Iran can repeatedly threaten.
The United States possesses advanced aircraft, long-range bombers, precision-guided missiles, aircraft carriers, sophisticated intelligence systems and extensive air and missile defenses.
But these systems require fuel, spare parts, maintenance, communications, ammunition, runways, ports and personnel.
Iran’s strategy has been to attack that supporting infrastructure.
This creates what military planners describe as an access and denial problem.
Tehran does not need to defeat the U.S. military in a conventional battle or occupy Gulf territory. It can instead attempt to make American operations increasingly expensive, unpredictable and politically difficult.
That is the significance of McCaffrey’s warning that Iran could gain leverage over access to the Gulf.
The statement should not be interpreted as meaning that Iran has acquired political control over Gulf states. Saudi Arabia, Bahrain, Kuwait, Qatar and the United Arab Emirates retain sovereign authority over their territory and security relationships.
Rather, Iran could gain the ability to impose sufficient military risk that both host governments and Washington reconsider how much American military infrastructure should remain within missile range.
The vulnerability emerged during Operation Epic Fury, the U.S. campaign against Iran launched on February 28, 2026, alongside Israel’s Operation Roaring Lion.
The United States said the operation was intended to destroy Iranian offensive missile capabilities, degrade its military infrastructure, damage its naval forces and prevent Iran from developing nuclear weapons. The U.S. Department of War describes the mission as focused on Iranian missiles, missile production, naval forces and security infrastructure.
The opening phase represented a massive American and Israeli military effort.
U.S. and Israeli forces struck Iranian leadership, air-defense systems, missile sites, military bases, command facilities and other strategic targets. Independent assessments at the beginning of the operation described the campaign as a broad multidomain assault involving air, naval, missile, cyber and electronic-warfare capabilities.
The United States subsequently claimed major battlefield successes.
But Iran’s ability to retaliate demonstrated a critical limitation.
Even after suffering extensive destruction, Iranian missile and drone forces retained enough capability to threaten American facilities and regional infrastructure.
That created a strategic paradox.
Washington could destroy large portions of Iran’s military infrastructure while still being unable to guarantee the security of the bases from which its own regional military power was generated.
One of the clearest consequences has been pressure on American logistics.
Reports circulating during the conflict indicated that damage to Bahrain’s naval infrastructure forced greater reliance on the distant Diego Garcia facility in the Indian Ocean.
That shift dramatically increases the distance between American logistical support and the Persian Gulf.
The longer the supply route, the greater the demand for ships, aircraft, fuel, crews, maintenance capacity and protection.
A supply movement that once required relatively short transit times may instead take considerably longer when equipment must travel from the Indian Ocean or Europe.
The effect is cumulative.
Every additional mile consumes resources.
Every additional staging point creates another facility that must be protected.
Every additional transfer increases the possibility of mechanical problems, weather disruption, intelligence exposure or attack.
The problem becomes even more serious for aircraft.
Fighter aircraft operating from bases farther from Iran require more aerial refueling. Tankers become essential to maintaining combat-air patrols, strike missions and surveillance operations.
But tanker aircraft are themselves high-value assets.
The United States therefore faces a trade-off: moving aircraft farther from Iran improves their protection from short- and medium-range missile threats, but increases the logistical burden required to put those aircraft over the battlefield.
One possible response is a westward shift.
Western Saudi Arabia could provide greater geographic depth while preserving American access to the Middle East.
Facilities near the Red Sea are farther from Iran than major installations along the Persian Gulf. They could therefore reduce the vulnerability of American aircraft and support infrastructure to Iranian short-range systems.
Prince Sultan Air Base near Riyadh could also play a larger role.
But relocation would not solve the problem automatically.
A large concentration of aircraft and support equipment at a single alternative location could simply create another lucrative target.
The Pentagon would therefore need to combine geographic relocation with dispersion.
That could mean smaller detachments, temporary operating locations, alternate runways, mobile fuel systems, dispersed aircraft shelters, decoy facilities and redundant command-and-control networks.
The objective would be to ensure that the destruction of one installation does not cripple an entire operational network.
Jordan and Israel are also potential components of a revised architecture.
Bases farther west would provide additional warning time against Iranian missiles and drones and could reduce the immediate threat to aircraft parked on the ground.
Israel offers highly developed military infrastructure and advanced air-defense capabilities.
But expanding the American presence there would bring its own political and security complications.
Israel is already deeply involved in the conflict with Iran, and facilities used by U.S. forces could become priority targets for Iranian retaliation.
There would also be concerns surrounding intelligence security, sensitive technology and the political consequences of deeper American military integration.
Southern Europe could offer still greater geographic distance.
American facilities in countries such as Italy, Greece and other Mediterranean locations could serve as staging and logistics hubs for Middle Eastern operations.
But the farther forces move from the Gulf, the greater the logistical burden.
Aircraft would need additional tanker support. Supplies would need longer routes. Ships would require more time to reach the theatre. Commanders would have less immediate access to the Persian Gulf.
The solution, therefore, is unlikely to be a simple move from the Gulf to Europe.
Instead, the United States could develop a layered system combining smaller Gulf facilities with larger western and distant regional hubs.
The most difficult decision could involve Bahrain.
The island nation hosts the headquarters of the U.S. Fifth Fleet and has long been central to American naval operations in the Gulf.
Abandoning Bahrain completely would create significant operational and political consequences.
The United States would lose a major naval command center and would have to recreate elements of its infrastructure elsewhere.
Yet keeping the entire existing architecture could also leave Washington exposed to another round of attacks.
A possible compromise would be to preserve Bahrain as a command and maritime-access location while moving vulnerable support functions elsewhere.
Critical communications systems could be hardened and duplicated. Logistics could be distributed among several ports. Personnel could be dispersed.
Such an arrangement would make it more difficult for Iran to disable the Fifth Fleet’s regional infrastructure with a limited number of attacks.
Kuwait has historically been central to American ground-force logistics because of its geographic position and access to regional transportation networks.
But its proximity to Iran makes it particularly vulnerable.
Large bases and storage facilities near the Gulf can be targeted quickly, leaving limited warning time.
A reduction in Kuwait could therefore become part of a broader American effort to reduce fixed infrastructure within Iran’s immediate strike envelope.
However, abandoning or dramatically reducing Kuwaiti facilities would create new logistical problems.
The United States would have to move equipment, ammunition and support capabilities farther west, increasing transportation requirements and reducing the efficiency of established supply corridors.
The decision will therefore depend on whether the cost of rebuilding and defending the facilities is greater than the cost of operating from farther away.
Iran’s military strategy has increasingly emphasized asymmetric capabilities.
Ballistic missiles, cruise missiles, one-way attack drones, naval mines, small boats, cyber operations and other relatively inexpensive systems can impose disproportionate costs on a technologically superior opponent.
This does not mean that Iran has achieved conventional military parity with the United States.
It has not.
But it does mean that Iran can exploit geography.
The Persian Gulf is narrow. American facilities are relatively predictable. Major ports, airfields and logistics hubs cannot easily be moved.
Iran’s missile forces, by contrast, can be dispersed and concealed.
Mobile launchers can be relocated. Decoys can complicate targeting. Underground facilities can protect portions of the arsenal. Drones can be produced and deployed at comparatively low cost.
The United States can destroy large numbers of these systems, but eliminating every mobile launcher and every reserve weapon is far more difficult.
The emerging U.S. approach could therefore emphasize survivability rather than concentration.
Instead of maintaining enormous permanent bases capable of supporting thousands of personnel and large numbers of aircraft, Washington could rely increasingly on smaller, distributed operating locations.
Aircraft could rotate among several airfields.
Fuel could be stored in multiple locations.
Maintenance teams could operate in mobile units.
Command systems could have multiple backup sites.
Naval forces could receive supplies from several ports rather than relying heavily on Bahrain.
Such a structure would be more resilient.
But it would also be more expensive and complicated.
Dispersed forces require more coordination, more transportation and more security personnel.
The United States would also become more dependent on allied governments providing access to airfields, ports, roads and airspace.
That makes diplomacy an essential component of military planning.
A major reduction in the U.S. Gulf presence would also send a political signal.
For decades, American military power has been a central element of the security architecture protecting Gulf monarchies and maintaining freedom of navigation.
If Washington substantially reduces its permanent presence, regional governments could question the durability of the American security commitment.
Some could increase their purchases of missile defenses and long-range strike systems.
Others might deepen security relationships with European or Asian powers.
Some could seek greater accommodation with Tehran.
Iran, meanwhile, could portray an American withdrawal as evidence that missile and drone warfare successfully forced Washington to reconsider its regional posture.
That is why the political presentation of any restructuring will matter.
If Washington describes the change as a deliberate transition toward a more resilient military architecture, it could be presented as adaptation.
If it appears to be an emergency retreat from damaged bases, Tehran could claim a major strategic victory.
Money will be another decisive factor.
Reconstructing damaged American facilities could cost billions of dollars, even before considering the cost of additional air defenses, hardened shelters and redundant infrastructure.
Recent reporting has put the initial repair bill at roughly $5 billion.
Washington therefore faces a fundamental choice.
It can spend billions restoring large bases to their prewar condition and then spend billions more protecting them.
Or it can invest in a smaller, distributed architecture designed from the beginning to survive missile and drone attacks.
The second option may ultimately prove more compatible with modern warfare.
There is no indication that Washington has finalized a comprehensive new Middle East basing strategy.
The Pentagon’s examination remains a planning exercise rather than an announced permanent force-posture decision.
The final outcome will depend on the trajectory of the conflict, the condition of Iranian missile forces, negotiations with Gulf governments, the security of the Strait of Hormuz and America’s competing military priorities in Europe and the Indo-Pacific.
The continuing confrontation has already demonstrated, however, that physical distance is no longer enough to guarantee the security of American military infrastructure.
The United States retains overwhelming advantages in air power, naval power, intelligence, precision weapons and global logistics.
But the Iranian campaign has shown that an adversary does not necessarily need to destroy those capabilities directly.
It can attack the infrastructure that allows them to operate.
That may be the most important lesson Washington carries forward from the conflict.
The future American military presence in the Middle East may therefore be smaller, more dispersed and less dependent on enormous permanent bases close to the Persian Gulf.
For Iran, the objective may not be to defeat the United States conventionally.
It may be enough to make American access increasingly difficult, expensive and politically complicated.
For Washington, the challenge now is to ensure that tactical military superiority can still translate into strategic access.
