Puerto Rico: A launchpad for empire in the Caribbean

The island, which has been continuously colonized since the 1490s, is a linchpin of US power projection overseas.

The archipelago of Puerto Rico is the oldest continuous colony in the world.

Ever since Columbus set foot on what’s believed to have been the northwest coastline of Borikén in November 1493, Puerto Rico has belonged to some colonial power. The Spanish called the archipelago “la llave de las Antillas,” the key to the Antilles, because of its geostrategic location. Spain set up “Fort” Puerto Rico as their first line of defense to protect their vast American dominions and fend off European competitors with the construction of two massive forts at Castillo San Felipe del Morro and Castillo San Cristobal. They also used the island as a commercial pit stop for galleons before crossing the Atlantic with their loot.

Puerto Rico transferred hands from Spain to Britain back to Spain, and since 1898, the island has been a colony of the United States. Since entering the global imperial system, Puerto Rico has been leveraged as a strategic enclave against Puerto Rican sovereignty, land, and livelihood.

Puerto Rico as War Booty

Spanish rule in Puerto Rico lasted for 405 years. The United States intervened in the brutal Cuban war for independence in 1898 on the side of the rebels and, in the end, subverted Cuban independence and claimed Spain’s territorial possessions in America and the Pacific in what is known as the Spanish-American War. By December 1898, the Treaty of Paris ceded the territories of Puerto Rico, Guam, the Philippines, and the Mariana Islands to the United States as war booty.

The colonial experiment continued under new management. Almost immediately, the Americans occupied abandoned Spanish military garrisons throughout the Island, including the enormous fortress El Morro. An army of administrators, teachers, scientists, engineers, religious clerics, businessmen, land speculators, and agriculture corporate representatives followed to re-engineer Puerto Rican society, economy, and the landscape, and to exploit its resources. Through this system, the Americans installed a new colonial order on the Island and instilled a new colonial subject.

Many of the same strategies used to subjugate American Natives were applied to Puerto Ricans. “Kill the Indian and save the man” became “civilize” the Puerto Rican “brute.” American teachers were systemically deployed to Puerto Rico to restructure the existing education system to prioritize American values and the English language, and missionaries sought to convert Puerto Ricans from Catholicism to American Protestantism. Just as they recruited Apache natives to fight rebel Apache bands, the U.S. Army set up an all-Puerto Rican Provisional Battalion to serve as auxiliaries to the U.S. military and help with population control. As more battalions were created, this grew into the 65th Infantry Regiment, nicknamed the “Borinqueneers,” who fully integrated into the U.S. Army and later served with distinction in the Korean War.

FOB Puerto Rico

As westward expansion and subjugation of native peoples solidified U.S. control in continental North America, American capitalists and policymakers continued the march for dominance southward and across the Pacific.  Puerto Rico continued to serve as a strategic enclave— a Forward Operating Base providing a bridge to the wider region as the “Gibraltar of the Caribbean” and a choke point of control.  With Puerto Rico as a garrison colony, Americans were able to project power across the Caribbean Basin and ward off potentially hostile European powers. Puerto Rico became the headquarters of the Department of Defense of the Antilles for the US Army, and the Naval Base Roosevelt Roads became the largest overseas U.S. naval installation in the world with the longest airstrip in Latin America. This military center, along with the American naval base in Guantanamo Bay, Cuba, was also tasked to defend, until the handover in 1999, the colonial enclave of the Panama Canal Zone.

U.S. citizenship was imposed upon Puerto Ricans in 1917 under the Jones Act. That same year the United States entered the Great War in Europe, and some 236,000 Puerto Ricans were served draft notice, with 20,000 deployed. Since then, Puerto Ricans have participated in every U.S. war and military conflict.

Militarization in Puerto Rico continues to be multipurpose. In addition to projecting US power in the Caribbean Basin, Puerto Rico has served as a training ground for the U.S. military to influence and train foreign troops for wars and conflicts. It served as a transit point for resources and supplies sent to Africa and Europe during the Second World War. It was a lab to experiment in modern warfare with modern weapons, such as napalm, Agent Orange, and depleted uranium. And it was a stage to rehearse large-scale combined arms military exercises later applied in major theaters of war such as the D-Day invasion of Normandy, the invasion of Panama, the bombings of Yugoslavia, and the invasion of Iraq.

The U.S. military’s footprint on the Puerto Rican landscape is vast and inescapable. The US military not only took over Spanish military posts but built four additional main military installations and many more auxiliary camps and installations, a series of connecting roads and railroads, antenna stations for telecommunication, and airstrips for cross-island movement of supplies and persons. Over 30 municipalities have had a military installation at one time or another. An island that is a little over 100 miles long and 36 miles wide has given up tens of thousands of acres of land to military installations with thousands of acres directly expropriated from small farmers. Vieques, an island municipality adjacent to the main island, had 27,000 out of 31,000 total acres of land appropriated for military use. Its people were forced to emigrate or relocate to what remained of the island. A similar fate befell Culebra, another island municipality, which together with Vieques would serve for decades as the largest range for combined arms military exercises that included large-scale bombings from naval ships, amphibious assaults, and air-to-surface target practice for fighter jets and bombers.

The militarization of Puerto Rico has had devastating ecological impacts. To expand the Spanish naval base in San Juan Bay, swamps and mangles were destroyed and filled with lumber, dirt, and minerals from a nearby quarry. Six miles south in Guaynabo, 1,515 acres were expropriated to establish Army Garrison Fort Buchanan, built with materials taken from the same quarry and forest, and which later grew to as large as 4,500 acres. To the east in Ceiba, a large swath of land from El Yunque was deforested for lumber to build Roosevelt Roads Naval Station. In Cayey, lumber from the Carite Forest built Fort Henry Barracks, the headquarters and training center for the 65th Infantry Regiment. Along the northern coast in Aguadilla, 3,796 acres of agricultural land was taken from small farmers to construct army base Camp Borinquen, which later became Remy Air Force Base and part of the Strategic Air Command, one of three major commands of the U.S. Air Force. These are just a few of the many military installations that have littered Puerto Rico throughout 124 years of colonization by the U.S.

Military Occupation with a Familiar Face

These military bases and installations have wreaked widespread damage in Puerto Rico in order to advance U.S. geostrategic interests in a variety of ways.

They have been vital to projecting power abroad and also to squashing rebellions at home, such as the uprisings of 1950 that championed independence from the United States. Not to mention, they leave behind huge contaminants and unexploded ordinance.  Such is the case in Vieques where the promised clean-up after the closing of the range has not manifested.  With technological advancement, many of these military facilities have since become obsolete and repurposed. The land and facilities were eventually turned over to the local government for their use and development, or to house other American federal agencies like the Coast Guard, Customs and Border Patrol, FBI, and DEA.

Today, the remaining facilities are home to roughly 100,000 U.S. military personnel and affiliates from the Puerto Rican National Guard, the Air National Guard, the Reserves of various components of the Armed Forces, some active duty service members, ROTC, Veterans Affairs, DoD civilians, and veterans, retired or otherwise – almost all being Puerto Ricans.  Although overt Anglo military presence on the island has diminished, its destructive and subjugating legacy remains, and a more subtle military occupation persists.

Puerto Rico saw its peak in overt American militarization during the Second World War up until the Vietnam War.  Most of these bases and facilities have been turned over to the local government for civilian use, like the Luis Muñoz Marin International Airport in San Juan   But some bases remain military facilities. At Camp Santiago, a large training center in Salinas, on the southern coast of Puerto Rico, National Guard troops train and do their drills. It’s also a place where officers and soldiers from throughout Latin America and the Caribbean receive training from U.S. military personnel. Fort Buchanan was temporarily the headquarters of the U.S. Southern Command when it transitioned from Panama to Doral, Florida.

The Puerto Rican National Guard, when activated, automatically integrates into the US Army and Air Force. They were activated in the recent so-called “War on Terror” and the invasion of Iraq.  The Reserves are already part of the U.S. Armed Forces. With a population of 3.2 million and another four million in the diaspora, Puerto Ricans already make up a very large demographic in the regular armed forces. This dual consciousness, of being Puerto Rican and an American soldier, also serves to solidify American colonialism in Puerto Rico.

Trump's war is a gift to Iran’s hardliners

Shi'ite Muslims hold posters of Iran's new supreme leader, Mojtaba Khamenei, alongside late Iranian Supreme Leader Ayatollah Ali Khamenei, as they take part in the religious procession marking the death anniversary of Imam Ali, son-in-law of Prophet Muhammad, during the fasting month of Ramadan, in Karachi, Pakistan, March 11, 2026.

Trump's war is a gift to Iran’s hardliners

Middle East

When the United States and Israel launched strikes on Iran on February 28 — an escalation that has already brought new suffering and uncertainty to millions of ordinary Iranians — the central debate quickly turned to whether the Islamic Republic might collapse. Some analysts argued that decapitating Iran’s leadership could produce rapid regime change, perhaps resembling the leadership removal in Venezuela earlier this year. Others warned that Iran’s political system was far more resilient.

Yet the more important point may lie elsewhere. Given the Islamic Republic’s internal dynamics, war could produce the opposite of what many expect. Rather than weakening the regime, the war may strengthen its most committed supporters — the ideological networks often labeled “hardliners” in Western media — while marginalizing the broader political middle, inside and outside the system, that favors non-violent and gradual change.

As Iran war rages, Washington opens a new front in Ecuador

Latin America

As the world’s attention is focused on the U.S. and Israeli war on Iran, the United States has, with little fanfare, opened another front in its expanding campaign against so-called “narco-terrorism” in the Western Hemisphere.

Since this new "war on drugs" began last year, U.S. military strikes on alleged drug-smuggling boats, as well as a direct military intervention in Venezuela, have claimed the lives of more than 250 people. Now, Ecuador, a country on the northwestern edge of South America, has become the latest site of Washington’s reinvigorated “war on drugs.” This escalation risks making the United States complicit in the human rights abuses of a government that is steadily dismantling its own country’s democracy, including by suspending the nation’s largest opposition party.

Israel’s push for Somaliland base raises fears of wider war

QiOSK

Bloomberg reported Wednesday that Israel is in talks with Somaliland officials to form a strategic security partnership, which might include granting Israel access to a military base or other security installation along the Somaliland coast from which it can launch attacks against Yemen’s Houthi rebels.

With war raging in the Middle East, the Horn of Africa is a particularly important geoeconomic and geopolitical puzzle piece. Its location near the Bab el-Mandeb strait, which connects ships traveling through the Red Sea with the Gulf of Aden and the Indian Ocean, makes it a strategic location from the perspective of global shipping, 10% to 12% of which travels through the strait annually.
