The Muslim Brotherhood’s 1991 blueprint for long-term institutional capture inside the United States described a “Civilization-Jihadist Process” whose goal is “eliminating and destroying Western civilization from within.”
That’s not activist hyperbole. Those words appear in a court exhibit from the largest terrorism-financing prosecution in U.S. history.
The document — titled “An Explanatory Memorandum on the General Strategic Goal for the Group in North America” and written by Mohamed Akram in May 1991 — was entered as a government exhibit in United States v. Holy Land Foundation, the 2007-2008 trial that tied CAIR’s founders to a Hamas fundraising network.
“ELIMINATING AND DESTROYING WESTERN CIVILIZATION FROM WITHIN” — 1991 MUSLIM BROTHERHOOD MEMORANDUM, COURT EXHIBIT
CAIR’s founders were officers of the Islamic Association for Palestine and the broader U.S. Palestine Committee network that prosecutors tied to Hamas fundraising. Hamas was designated a terrorist organization by the U.S. in 1997. CAIR itself was named an unindicted co-conspirator in that case — a designation a federal court later upheld against CAIR’s challenge. The FBI subsequently restricted formal outreach to CAIR at the national level.
In November 2025, Texas Governor Greg Abbott designated CAIR and the Muslim Brotherhood as foreign terrorist and transnational criminal organizations under state law — the first time a U.S. state made such a designation of an American-founded organization without a matching federal one. Florida followed suit in December 2025.
The memo’s actual weight is disputed. Georgetown’s Bridge Initiative and other critics note the memo was a personal letter from one author to Brotherhood colleagues asking for comment, not a document shown to have been formally adopted. The official 1991 conference report that followed does not reference it, and linguistic analysis finds the phrase “civilizational jihad” is vanishingly rare in the broader corpus of Islamist writing.
Nevertheless, a senior Brotherhood figure articulated a long-term institutional capture strategy in 1991. It entered the trial record of an organization with documented ties to CAIR’s founders. Its status as official, binding Brotherhood policy remains contested — but the document is real, and so are the convictions that followed.
What makes this fit the modern definition of a fifth column is the documented strategic vision of long-term settlement and institutional capture, court-tested organizational overlap with a Hamas-financing case, and now state-level terrorist designations layered onto ordinary civic and political activity by a much larger population of Muslim Americans who may or may not have any connection to it.
The analysis also identifies four other categories of networks loosely qualifying as modern fifth columns: documented Chinese, Iranian, and Cuban influence operations; far-left militant and propaganda networks (PSL, ANSWER, Antifa, and CCP-linked groups); mass illegal immigration and open borders advocacy; and transnational cartels exercising parallel authority in parts of the U.S. border region.
Foreign intelligence operations meet the 1936 standard literally. The House Select Committee on the CCP’s “United Front 101” memo describes the Chinese communists’ United Front Work Department (UFWD) as a Central Committee body coordinating influence over American universities, think tanks, civic groups, and diaspora organizations.
The FBI’s October 2022 raid on a secret Chinese police station operating out of the America ChangLe Association in New York — and tied to the Alliance for China’s Peaceful Reunification Network — is a concrete, court-referenced example. Talent recruitment programs (Thousand Talents and successors) have produced multiple DoD prosecutions of researchers who concealed CCP funding and IP-transfer obligations from U.S. institutions.
Iran’s Islamic Revolutionary Guard Corps has been directly tied to U.S. election interference. The Justice Department indicted three IRGC-linked cyber actors in 2024 for a hack-and-leak operation targeting the presidential race.
Cuba’s intelligence apparatus has a long, documented history of U.S.-facing operations. The Wasp Network and Ana Montes cases remain the clearest precedents.
The term “fifth column” originated in Madrid in 1936. On 30 September 1936, during the Spanish Civil War, a secret German telegram was the first document to record the phrase, attributing to Spanish General Francisco Franco a claim that four Nationalist army columns were closing on Madrid while a “fifth column” inside the city waited to attack the Republican defense from within.
On 3 October, communist propagandist Dolores Ibárruri (“La Pasionaria”) used the phrase publicly in Mundo Obrero but attributed it to General Emilio Mola, not Franco. No verified transcript of any Nationalist radio address or speech by Mola, Franco, or Gen. Gonzalo Queipo de Llano contains the phrase.
Historians remain split on whether Mola coined it, whether it was invented or embellished by Republican propagandists to justify wartime repression of suspected Nationalist sympathizers in Madrid, or some mix of both. What is not contested is the meaning it carried: a clandestine, coordinated network of sympathizers inside a besieged population, working to open the gates from within.
That original sense — hidden saboteurs under central military direction — is such a high bar that modern use of the term revolves around a broader definition: claims about fifth columns are far more common historically than documented fifth columns themselves, and the rhetoric tends to rise with ethnonationalist and geopolitical anxiety regardless of whether the underlying threat is real.
Political scientists now treat fifth-column politics as rhetoric, policy, or mobilization against domestic “enemies within.” Scott Radnitz of the University of Washington splits it into two types: subversive claims aimed at vulnerable minorities or immigrants and collusive claims aimed at elites said to serve a foreign power. Neither needs a hidden army or single chain of command. Both describe a domestic network — whether organized or not — whose activities, funding, or ideology line up with a foreign adversary, or that treats the U.S. constitutional order as illegitimate and works to replace it from the inside.
Several proto-fifth-column clusters operate in or around the U.S.: an immigrant-linked network tied to Muslim Brotherhood- and CAIR-affiliated groups, and a largely separate set of leftist and CCP-aligned organizations (PSL, ANSWER, Antifa, and UFWD-linked groups). They are not under one command, but their interests sometimes coincide — in opposition to Israel and U.S. immigration enforcement and in hostility to the legitimacy of the American constitutional order.
That overlap, even without central direction, can enable foreign leverage, parallel structures, or slow institutional capture over time.
A 2026 House Financial Services subcommittee hearing and a parallel Washington Times op-ed both describe a “red-green alliance” connecting Cuban state-linked entities (ICAP, Resumen Latino americano), Iran-aligned groups, and U.S. organizations including CodePink and the People’s Forum. The congressional hearing rests on named witnesses, nonprofit tax filings, and a financial paper trail. The op-ed rests on a single Israeli counterterrorism research report, public filings, and a photograph, with no cited government finding.
This analysis is Part I of a two-part examination. Part II will cover far-left militant and propaganda networks, examine where the interests among the categories align, and conclude with monitoring recommendations for the future.
The charges remain allegations. The case has not been proven in court.
