On February 18, 1976, President Gerald Ford issues Executive Order 11905, which includes the provision: "No employee of the United States Government shall engage in, or conspire to engage in, political assassination." The order comes in direct response to the Church Committee's revelations about CIA assassination plots against foreign leaders including Fidel Castro (Cuba), Patrice Lumumba (Congo), Rafael Trujillo (Dominican Republic), Ngo Dinh Diem (South Vietnam), and René Schneider (Chile). Ford acts through executive order rather than waiting for Congress to legislate — a choice that proves decisive for the history of intelligence accountability.
The Church Committee's "Alleged Assassination Plots Involving Foreign Leaders" report, published in November 1975, documents a systematic pattern: the CIA developed assassination capabilities, planned or attempted to kill at least five foreign leaders, and operated with varying degrees of presidential knowledge and authorization. The report reveals the "plausible deniability" doctrine — the practice of insulating presidents from direct knowledge of assassination orders so they could truthfully deny involvement — as a structural feature of the intelligence system rather than an aberration.
Ford's executive order establishes the ban, but its form is as significant as its content. By acting through executive order rather than statute, Ford ensures that the assassination ban is executive self-regulation — revocable by any future president with a stroke of a pen — rather than a binding law enacted by Congress with enforcement mechanisms, penalties, and judicial review. Congress never passes a statutory assassination ban, despite multiple attempts. The intelligence community and its executive branch allies successfully resist legislative action by arguing that an executive order is sufficient and that a statute would create legal complications in ambiguous operational situations.
The order's careful wording also creates interpretive space. It bans "political assassination" without defining the term. Does a military strike targeting a specific individual constitute assassination? Does supporting a coup that results in a leader's death? Does providing intelligence to allies who conduct their own targeted killings? These ambiguities are not accidental — they preserve operational flexibility while satisfying the public demand for reform.
The assassination ban survives in modified form through subsequent administrations. Carter's Executive Order 12036 (1978) strengthens it slightly; Reagan's Executive Order 12333 (1981) reformulates it as: "No person employed by or acting on behalf of the United States Government shall engage in, or conspire to engage in, assassination." But the ban's executive-order status means it exists at the pleasure of the president. After September 11, 2001, the Bush administration interprets the ban as inapplicable to "enemy combatants" in the War on Terror, enabling the targeted killing program that expands dramatically under Obama's drone warfare and continues through subsequent administrations.
The larger pattern EO 11905 establishes is intelligence reform through executive self-regulation rather than democratic accountability. The president who controls the intelligence agencies also controls the rules governing them. This is the inverse of democratic oversight: instead of the people's representatives setting boundaries that the executive must obey, the executive sets its own boundaries and can change them at will. The Foreign Intelligence Surveillance Act (FISA, 1978), the Intelligence Oversight Act (1980), and the creation of congressional intelligence committees partially address this problem — but the assassination ban remains, to this day, an executive order rather than a law.
The episode demonstrates a recurring dynamic in post-scandal reform: the intelligence community concedes the principle (assassination is wrong) while capturing the mechanism (the ban is self-imposed and revocable), ensuring that the substance of reform remains permanently under executive control.
