The recent escalation between the United States, Israel, and Iran has drawn global attention to a network that has existed quietly for decades: the vast system of American military bases across the Middle East and around the world.
In the wake of coordinated U.S. and Israeli strikes against Iranian military targets—and Iran’s retaliatory missile and drone attacks on several American installations—these bases have suddenly become central to global headlines. Locations that once operated largely outside public awareness, such as Al Udeid Air Base, Naval Support Activity Bahrain, and Al Dhafra Air Base, are now key battlegrounds in an expanding regional confrontation.
Yet the presence of American forces across the Middle East is not a recent development. It is the result of more than a century of strategic evolution—from early imperial expansion to Cold War containment and modern counterterrorism campaigns. Understanding why these bases exist requires looking back at the long historical arc of American foreign policy.
For much of the 19th century, the United States largely adhered to an isolationist foreign policy rooted in the warnings of George Washington, who cautioned against becoming entangled in European conflicts. The young republic focused instead on internal development and continental expansion.
Following the end of the American Civil War, however, the country emerged unified and increasingly confident. The ideology of Manifest Destiny had already driven American expansion westward, displacing Native American populations and extending U.S. territory to the Pacific Ocean.
By the late 19th century, the United States was beginning to resemble other imperial powers of the era.
A pivotal moment came in 1898 with the Spanish–American War. The conflict transformed the United States from a continental power into an overseas imperial actor. One of the central figures behind the war was Theodore Roosevelt, who, while serving as Assistant Secretary of the Navy, advocated aggressive action against Spain. Roosevelt famously resigned from his government post to form the volunteer cavalry unit known as the Rough Riders and personally fight in the war.
The brief conflict ended with the rapid defeat of Spain’s declining empire. In the resulting settlement, Spain ceded several territories to the United States, including Guam, Puerto Rico, and the Philippines.
Another Spanish colony, Cuba, was placed under American occupation before gaining formal independence in 1902. Even after Cuban independence, Washington retained control of the naval facility at Guantanamo Bay Naval Base—a base that remains operational today and represents the oldest continuous U.S. military installation overseas.
These acquisitions marked the beginning of America’s overseas basing network.
Despite its growing global influence, the United States maintained a largely isolationist stance during the early decades of the 20th century. That changed dramatically during the lead-up to the World War II.
In 1940, with Britain facing the threat of Nazi invasion, Franklin D. Roosevelt negotiated the historic Destroyers-for-Bases Agreement.
Under the deal, the United States transferred aging naval destroyers to Britain in exchange for 99-year leases on military bases across the Western Hemisphere. These included facilities in Newfoundland, Bermuda, Bahamas, Jamaica, Trinidad, and Guyana, then known as British Guiana.
The geographic logic behind these bases was clear. American planners wanted to secure the Caribbean and protect the strategic Panama Canal, a vital shipping route connecting the Atlantic and Pacific oceans.
Shortly afterward, the United States also took over the defense of Iceland in 1941, relieving British forces and strengthening Allied monitoring of German naval operations in the North Atlantic.
By the time the United States formally entered World War II after the Attack on Pearl Harbor, the foundations of a global basing network had already been laid.
The end of World War II marked the emergence of the United States as a global superpower. Almost immediately, it found itself locked in strategic competition with the Soviet Union in what became known as the Cold War.
During this period, Washington dramatically expanded its overseas military presence.
The strategic thinking behind this expansion drew heavily on the ideas of geopolitical theorists such as Halford Mackinder and Nicholas Spykman.
Mackinder argued that whoever controlled the “Heartland”—the vast interior of Eurasia—could dominate the world. Spykman modified this concept by arguing that control of the “Rimland,” the coastal areas surrounding Eurasia, was actually the key to global power.
To prevent Soviet expansion, the United States sought to encircle the USSR with alliances and military bases stretching from Western Europe through the Middle East to East Asia.
This strategy led to the formation of the North Atlantic Treaty Organization and the establishment of major bases in allied countries such as Germany, Japan, and South Korea.
At its peak during the Cold War, the United States operated more than 1,000 military installations abroad.
Most of these bases existed under legal arrangements known as Status of Forces Agreement, which define the legal framework governing American troops stationed in foreign countries.
These agreements ensure that the presence of U.S. forces is formally authorized by host governments. When agreements expire or political circumstances change, the United States typically withdraws—as it did from Iraq in 2011.
After the collapse of the Soviet Union in 1991, the United States reassessed its global military footprint.
With the primary adversary gone, Washington launched a major restructuring effort known as the Base Realignment and Closure process.
Between the late 1980s and mid-2000s, hundreds of military facilities were closed or consolidated. In total, 424 installations were shut down, though many of these were domestic bases.
However, this reduction proved temporary.
The September 11 attacks fundamentally reshaped U.S. military strategy.
The subsequent wars in Afghanistan and Iraq required a dense network of bases across the Middle East to support large-scale operations.
Although American involvement in the region predates 9/11—largely due to the strategic importance of oil—the wars dramatically expanded the scale of the U.S. military presence.
- Al Udeid Air Base – the forward headquarters of United States Central Command
- Naval Support Activity Bahrain – home of the United States Fifth Fleet
- Camp Arifjan – headquarters of United States Army Central
- Al Dhafra Air Base – a major hub for American air operations
Temporary facilities known as forward operating bases were also established in Iraq and Afghanistan to support combat operations.
Even in an era of long-range missiles and advanced drones, geographic proximity remains strategically crucial.
Operating aircraft from nearby bases reduces the need for mid-air refueling and allows faster response times. Missiles launched from closer distances have shorter flight times, making interception more difficult.
Naval bases near chokepoints like the Persian Gulf and Red Sea enable rapid deployment of aircraft carriers and destroyers.
For the United States, this network allows rapid power projection across the Middle East, North Africa, and parts of South Asia.
This infrastructure has become central to the ongoing confrontation with Iran.
Following joint American and Israeli strikes launched on 28 February 2026 targeting Iranian missile facilities, air defenses, and leadership compounds, Iran responded with a wave of missile and drone attacks across the region.
- Al Udeid Air Base
- Naval Support Activity Bahrain
- Al Dhafra Air Base
- Ali Al Salem Air Base
- Muwaffaq Al‑Salti Air Base
American officials confirmed the first U.S. casualties of the conflict—three soldiers stationed in Kuwait.
These attacks highlight the inherent vulnerability of forward-deployed bases: they enable power projection but also sit within range of adversaries.
Washington has long regarded Iran as one of its most persistent regional adversaries.
Since the Iranian Revolution led by Ruhollah Khomeini, the Iranian state has defined itself partly through opposition to the United States.
Iran has also supported numerous regional groups opposed to U.S. and Israeli interests, including Hezbollah, Hamas, and the Houthi movement.
American officials argue that the Islamic Revolutionary Guard Corps plays a central role in coordinating these proxy networks.
The recent offensive reportedly targeted command centers, missile launch systems, naval assets, and senior leadership figures.
Among those killed was Iran’s Supreme Leader, Ali Khamenei, according to reports from Israeli and American officials.
Iran entered the conflict facing significant internal and external pressures.
Many of its regional allies had been weakened following the escalation triggered by the Hamas attack on Israel, which brought sustained Israeli and American military pressure on Iran’s broader network.
Domestically, the Iranian government has also faced rising unrest. Protests earlier this year were met with violent repression, with thousands reportedly killed during crackdowns aimed at suppressing dissent.
These internal tensions have led some analysts to argue that Iran’s leadership was operating from a position of relative weakness when the strikes occurred.
Despite the death of senior leaders and the destruction of military infrastructure, the outcome of the conflict remains uncertain.
The IRGC is not simply a conventional military organization; it is an ideological force deeply embedded in Iran’s political and economic system. That makes regime change from external pressure extremely difficult.
Some Iranian expatriates and dissidents have celebrated the death of the Supreme Leader. Others fear the potential for chaos, fragmentation, or civil war.
Within parts of the Shiite world, meanwhile, Khamenei’s death has been mourned as the loss of a figure seen as resisting Western influence.
Ultimately, the fate of Iran—and the broader Middle East—remains uncertain.
The United States’ global network of military bases, built over more than a century, has once again proven central to its ability to project power far from home.
But those same installations also draw American forces directly into the front lines of regional conflicts.
For Iran, the coming months may determine whether the political system created by the 1979 revolution can survive mounting internal unrest, leadership losses, and sustained external pressure.
The country once stood as one of the Middle East’s most dynamic centers of culture, education, and development.
