U.S. Military Bases in Puerto Rico: The Island as Strategic Colony
Since 1898, the U.S. military has used Puerto Rico as a strategic military platform — establishing major bases including Roosevelt Roads Naval Station, Ramey Air Force Base, Fort Allen, Fort Buchanan, and the Vieques and Culebra bombing ranges. At its peak, the military controlled approximately 13% of Puerto Rico's land area. The military presence shaped the island's geography, economy, environment, and political status — making Puerto Rico a key piece of U.S. military infrastructure in the Caribbean.

The Borinqueneers: Puerto Rico's 65th Infantry Regiment
The 65th Infantry Regiment — known as the Borinqueneers — was a U.S. Army infantry unit composed primarily of Puerto Rican soldiers who served with distinction in World War I, World War II, and the Korean War. Despite facing systematic discrimination, language barriers, and being one of the last segregated units in the U.S. Army, the Borinqueneers earned extraordinary combat honors. Their story embodies the colonial paradox: Puerto Ricans fighting and dying for a democracy that denied them the vote.

Puerto Rico National Guard: Fighting America's Wars Without a Vote
Puerto Ricans have served in every U.S. military conflict since World War I — over 200,000 in total — despite being unable to vote for the Commander-in-Chief who sends them to war. The Puerto Rico National Guard has been deployed to Iraq, Afghanistan, and dozens of other missions.

La Operación: Mass Sterilization of Puerto Rican Women (1930s-1970s)
Between the 1930s and 1970s, approximately one-third of Puerto Rican women of childbearing age were sterilized — the highest sterilization rate in the world. The program, driven by U.S. eugenics ideology and economic policy, targeted poor and working-class women who often were not fully informed about the permanence of the procedure.

Puerto Rican Political Prisoners: The Cost of Demanding Freedom
Throughout the 20th and into the 21st century, Puerto Ricans who actively fought for independence were imprisoned by the United States — from Pedro Albizu Campos (1936, 1950) through the Nationalist prisoners of the 1950s, the FALN (Fuerzas Armadas de Liberación Nacional) prisoners of the 1980s, to Oscar López Rivera (released 2017). The existence of political prisoners from a U.S. territory contradicts the American narrative of democracy and freedom.

FBI Surveillance of the Independence Movement: FOIA Revelations
Freedom of Information Act (FOIA) requests and declassified documents have revealed the extraordinary scope of FBI surveillance of Puerto Rican independence advocates — over 100,000 carpetas (intelligence files), infiltration of political organizations, agent provocateur operations, and coordination with Puerto Rican police in what constitutes one of the longest-running political surveillance programs in U.S. history.

Federal Minimum Wage Application: Colonial Labor Economics
The application of the federal minimum wage to Puerto Rico has been a contested issue for decades — initially set lower than mainland rates, then equalized in 1983, with ongoing debate about whether the federal minimum helps or harms Puerto Rico's economy, revealing how colonial economic policy creates impossible choices.

The Popular Democratic Party (PPD): Architects of the Colonial Compromise (1938-present)
The Popular Democratic Party (PPD), founded by Luis Muñoz Marín in 1938, created Puerto Rico's Commonwealth status (Estado Libre Asociado, 1952) — a political arrangement that its architects called 'self-governance' but that the United Nations, independence advocates, and many legal scholars consider continued colonialism under a new name.

Camp Santiago and Military Contamination of Salinas
Camp Santiago, a U.S. military training facility in Salinas, has contaminated surrounding communities with perchlorate, heavy metals, and unexploded ordnance, contributing to elevated cancer rates in one of Puerto Rico's poorest municipalities.

Puerto Rican Independence Party (PIP): 78 Years of Electoral Struggle
The Puerto Rican Independence Party (PIP), founded in 1946 by Gilberto Concepción de Gracia, has maintained an unbroken 78-year electoral presence advocating for Puerto Rican sovereignty through democratic means — despite systematic harassment, surveillance, and voter suppression.

First Elected Governor: Limited Self-Government (1948)
In 1948, Puerto Ricans voted for their own governor for the first time — electing Luis Muñoz Marín. For 50 years (1898-1948), governors had been appointed by the U.S. President, making Puerto Rico one of the last places in the Western Hemisphere where the chief executive was imposed by an external power.

Carpetas: Government Surveillance Program
For decades, the Puerto Rico Police maintained secret surveillance files ("carpetas") on over 150,000 independence supporters, journalists, labor organizers, and political dissidents.

Puerto Rico's Electoral System: Democracy Within the Colony
Puerto Rico's electoral system — in which voters elect a governor, legislature, and municipal governments but cannot vote for president or elect voting members of Congress — creates a unique form of limited democracy. The island's multi-party system is organized primarily around the status question (statehood vs. commonwealth vs. independence) rather than left-right ideology, and the emergence of new parties like the Movimiento Victoria Ciudadana signals a potential realignment.

The Suppression of the Nationalist Movement: State Terror in the 1950s
Following the Jayuya Uprising (October 30, 1950), the U.S. and Puerto Rican colonial governments launched a systematic campaign to destroy the independence movement — bombing Jayuya and Utuado from the air (the only time U.S. citizens have been bombed by their own government), imprisoning hundreds of Nationalists, and creating a pervasive surveillance state through the 'carpetas' system of political files that lasted for decades.

Public Law 600 and the 'Compact' Illusion (1950-1952)
Public Law 600 (1950) authorized Puerto Rico to draft its own constitution, leading to the establishment of the Commonwealth (Estado Libre Asociado) in 1952 — which critics call a colonial façade that changed nothing about U.S. sovereignty.

U.S. Government Radiation Experiments in Puerto Rico
Declassified documents and the 1994 Advisory Committee on Human Radiation Experiments confirmed that the U.S. government conducted radiation experiments on unwitting subjects during the Cold War — lending credibility to Pedro Albizu Campos's claims of being irradiated in prison.

65th Infantry Regiment (Borinqueneers) in the Korean War
The 65th Infantry Regiment — the Borinqueneers — was an all-Puerto Rican U.S. Army unit that fought with distinction in Korea, earning the Congressional Gold Medal. Yet the soldiers fought for a country that denied them full citizenship rights and was simultaneously bombing Jayuya and imprisoning independence leaders at home.

Puerto Ricans in Korea: The Borinqueneers' Forgotten Sacrifice
The 65th Infantry Regiment — the all-Puerto Rican Army unit known as the 'Borinqueneers' — served in some of the Korean War's most brutal battles, including the Chosin Reservoir. Despite extraordinary valor, the regiment was subjected to a mass court-martial in 1953 when over 90 soldiers refused to continue fighting under conditions of racism and command failure. The Congressional Gold Medal was awarded in 2014 — 60 years late.

Constitutional Convention of 1951-1952: Drafting the Colonial Constitution
The 1951-1952 Constitutional Convention drafted Puerto Rico's constitution — a document that included broader rights than the U.S. Constitution but was subject to congressional approval. Congress struck several provisions, including the right to education and work, demonstrating that Puerto Rico's 'self-governance' was subject to colonial veto.

Federal Death Penalty in Puerto Rico: Imposed Against the People's Will
Puerto Rico abolished the death penalty in its 1952 Constitution, but the federal death penalty still applies on the island — meaning Puerto Ricans can be executed under a law passed by a Congress in which they have no vote, overriding their own constitutional prohibition.

The Statehood Movement: Assimilation as Strategy and Debate
The statehood movement — represented primarily by the Partido Nuevo Progresista (PNP) since 1967 — argues that Puerto Rico's colonial problems can be solved through full incorporation as the 51st state. The movement has won multiple non-binding plebiscites but never achieved congressional action, revealing the limits of working within the colonial system.

July 25: Competing Commemorations and Colonial Memory
July 25 is Puerto Rico's most contested date: it marks both the U.S. invasion of 1898 and the establishment of the Commonwealth in 1952, making it simultaneously a day of colonial conquest and ostensible self-governance — a contradiction that encapsulates Puerto Rico's political dilemma.

Puerto Rico's Bill of Rights: Broader Than America's, Weaker Than Paper
Puerto Rico's 1952 Constitution included a bill of rights broader than the U.S. Bill of Rights — including prohibitions on the death penalty, wiretapping, and discrimination — but Congress stripped its most progressive provisions, and federal law can override any of its guarantees.

United Nations Resolutions on Puerto Rico's Colonial Status
The UN has passed over 40 resolutions reaffirming Puerto Rico's right to self-determination, while the U.S. removed Puerto Rico from the UN's list of non-self-governing territories in 1953 by a narrow vote.

The Birth Control Pill Trials: Puerto Rican Women as Test Subjects (1955-1960)
In the mid-1950s, researchers Gregory Pincus and John Rock chose Puerto Rico as the primary testing ground for the first oral contraceptive pill — Enovid. Puerto Rican women were selected because they were considered 'compliant' subjects, birth control was not illegal in Puerto Rico (unlike many U.S. states), and the colonial population control ideology supported the research. The women were not told they were part of an experiment, were not adequately informed of side effects (which were severe), and three women died during the trials.

Agent Orange Testing in Puerto Rico's Forests
Before Agent Orange was deployed in Vietnam — where it caused cancer, birth defects, and environmental devastation affecting millions — the U.S. military tested herbicidal warfare agents in Puerto Rico's tropical forests. El Yunque National Forest and other sites were used as testing grounds, exposing Puerto Rican ecosystems and nearby communities to toxic chemicals.

Puerto Ricans in the Vietnam War: Colonial Soldiers in an Imperial War
Over 48,000 Puerto Ricans served in the Vietnam War, with approximately 345 killed in action — a disproportionate sacrifice from a territory whose residents could not vote for the commander-in-chief who sent them to war. Puerto Rican soldiers fought in Southeast Asia while their island remained a colony of the country they served, unable to vote in presidential elections or have voting representation in Congress.

Puerto Rico Status Plebiscites (1967-2020)
Puerto Rico has held six non-binding status plebiscites (1967, 1993, 1998, 2012, 2017, 2020), none of which have resulted in a change to the island's territorial status because Congress is not obligated to act on the results.

Status Plebiscites: The Colonial Democracy Illusion (1967-2024)
Puerto Rico has held seven status plebiscites or referendums (1967, 1993, 1998, 2012, 2017, 2020, 2024) — none of which has changed anything, because the U.S. Congress has no obligation to honor the results, making each vote an exercise in colonial democracy theater.

UN Decolonization Committee: International Recognition of Colonial Status
Since 1972, the United Nations Special Committee on Decolonization has passed over 40 resolutions affirming Puerto Rico's right to self-determination — making Puerto Rico one of the most discussed colonial cases in international law, while the United States consistently ignores UN recommendations.

Supplemental Security Income (SSI) Exclusion from Puerto Rico
Puerto Rico residents are excluded from Supplemental Security Income (SSI), the federal safety-net program for elderly, blind, and disabled Americans. This exclusion, upheld by the Supreme Court in Vaello Madero (2022), affects approximately 300,000 Puerto Ricans who would be eligible if they lived on the mainland.

Section 936: Pharmaceutical Colony and Its Collapse (1976-2006)
Section 936 of the Internal Revenue Code (1976-2006) allowed U.S. corporations to operate in Puerto Rico virtually tax-free, turning the island into a pharmaceutical manufacturing hub — then its repeal triggered an economic collapse that led directly to the debt crisis and PROMESA.

The Cerro Maravilla Murders (1978): Police Assassination of Independence Activists
On July 25, 1978 — the anniversary of the U.S. invasion of Puerto Rico — two young independence activists, Carlos Soto Arriví (18) and Arnaldo Darío Rosado Torres (24), were lured to a police ambush at a telecommunications tower atop Cerro Maravilla in the central mountains. After surrendering, both men were executed by police officers. The subsequent cover-up, investigation, and trials exposed the depths of political repression in Puerto Rico and led to the conviction of police officers for murder.

Harris v. Rosario: Supreme Court Upholds Unequal Welfare (1980)
In Harris v. Rosario (1980), the Supreme Court ruled 6-3 that Congress can provide lower welfare benefits to Puerto Rico than to states — because the Territorial Clause gives Congress virtually unlimited power over territories and Puerto Ricans don't pay federal income tax.
