Muslim Brotherhood National Security Debate: Post-9/11 Lessons and U.S. Policy

The Muslim Brotherhood national security debate has resurged following a September 13, 2026 NewsNation segment examining post-9/11 national unity and the organization's alleged influence networks. The discussion highlighted competing assessments of the Brotherhood's activities in America, the Democratic Party's approach to the organization, and what has—and has not—changed in U.S. counterterrorism policy since 2001. This debate matters because it touches on fundamental questions about civil liberties, foreign influence, and how democracies balance security with constitutional protections.

Why Did the U.S. Designate Muslim Brotherhood Branches as Terrorist Organizations?
In January 2026, the United States designated three Muslim Brotherhood branches—in Egypt, Jordan, and Lebanon—as terrorist organizations . The Treasury Department accused the Egyptian and Jordanian branches of providing material support to Hamas, while the State Department designated the Lebanese branch, also known as Jamaa Islamiya, as both a Foreign Terrorist Organization (FTO) and a Specially Designated Global Terrorist (SDGT) . U.S. Under Secretary of the Treasury John K. Hurley stated: "The Muslim Brotherhood has inspired, nurtured, and funded terrorist groups like Hamas, that are direct threats to the safety and security of the American people and our allies" .

What Is the Muslim Brotherhood's Alleged Strategy in North America?
The debate often centers on a 1991 document titled "Explanatory Memorandum on the General Strategic Goal for the Group in North America," authored by Mohamed Akram . The memorandum describes the Brotherhood's work in America as "a kind of grand Jihad in eliminating and destroying the Western civilization from within" . It outlines a gradualist strategy focused on building Muslim communities through mosques, schools, charities, and professional organizations, emphasizing "patience and gradual growth rather than quick political victories" . Critics interpret this as a plan to transform Western society from within, while supporters argue the language is ideological and religious rather than a call for violence .

What Organizations Are Linked to the Muslim Brotherhood in America?
The Council on American-Islamic Relations (CAIR) is the most prominent organization frequently linked to the Brotherhood in public debate . CAIR's co-founder and Executive Director, Nihad Awad, publicly read a key passage from the 1991 memorandum at a 1994 symposium, stating: "The Ikhwan must understand that their work in America is a kind of grand Jihad in eliminating and destroying the Western civilization from within" . The 1991 document lists numerous Islamic organizations and encourages coordination among them . However, CAIR denies any ties to Hamas or the Muslim Brotherhood, describing itself as a domestic civil rights organization .

What Is the 1991 Explanatory Memorandum and Why Does It Matter?
The 1991 memorandum is a foundational document in the debate over the Muslim Brotherhood's presence in America . It outlines a long-term strategy emphasizing youth education, leadership development, and institutional influence . The document has been cited in congressional testimony and by critics who argue it reveals the Brotherhood's true intentions . Legal analysts note that while the memorandum provides ideological context, U.S. law requires evidence of direct material support to designated terrorist organizations for criminal prosecution .

How Has U.S. Counterterrorism Policy Evolved Since 9/11?
Since the September 11 attacks, U.S. counterterrorism policy has shifted from a broad "war on terror" framework to a more targeted approach . The Trump administration has pursued a graduated strategy, designating specific Brotherhood branches rather than the entire organization . The November 2025 executive order established a 30-day reporting requirement and 45-day action timeline for designations . Analysts note that past administrations resisted designating the Brotherhood as a whole due to its diverse branches and concerns about destabilizing political consequences.
