Executive summary

The Andinia Plan is a long-standing antisemitic conspiracy alleging a Zionist plot to carve a Jewish state out of Patagonia in southern Argentina and Chile; it originated in Argentine far‑right circles in the 20th century and persists today despite an absence of credible evidence [1] [2]. Scholars, journalists and civil‑society watchdogs have repeatedly described the story as a fabrication that distorts historical Jewish migration and has been used as a rhetorical weapon against Jewish communities [3] [4].

1. Origins: a rumor born in the 1970s military and political milieu

The phrase “Plan Andinia” first surfaced in a leaflet circulated among Argentine military officers in 1971 and was popularized by ultranationalist figures such as Walter Beveraggi Allende; the narrative drew on, and wildly distorted, real historical facts about Jewish agricultural colonies and migration to Argentina in the late 19th and early 20th centuries [3] [2] [5]. During Argentina’s later military dictatorship the idea even reached interrogation rooms—Jacobo Timerman and other Jewish prisoners reported being questioned about a supposed Israeli plan for Patagonia—showing how the myth was institutionalized and weaponized by state actors [5].

2. What the conspiracy claims and the flimsy “evidence” marshaled for it

Proponents of the Andinia Plan claim coordinated land purchases, demographic infiltration (citing Israeli backpackers in Patagonia), NGO green‑land projects and historical Zionist proposals as proof of a secret program to secede Patagonia and create a Jewish state; these claims are repeatedly assembled from disparate, unrelated facts and anecdote rather than from documents or verifiable operational plans [6] [7] [2]. Reported “evidence” typically consists of isolated land transactions, tourist patterns and decades‑old proposals for Jewish settlement—none of which, on inspection, amount to a clandestine national‑secession scheme [6] [3].

3. Scholarly and institutional debunking: no credible proof, plenty of refutation

Academic studies, mainstream journalists and Jewish‑monitoring organizations have concluded there is no evidence the Andinia Plan ever existed as an organized project; the Anti‑Defamation League and research centers cite the absence of documentary proof and characterize the story as antisemitic fiction [3] [5] [4]. Contemporary reporting and encyclopedia summaries note that the Zionist movement abandoned any Argentine‑based state proposals long before the conspiracy’s rise, and that Argentine Jewish institutions were integrated into national life rather than secretly plotting secession [1] [6].

4. How the myth persists: narrative fit, political utility and modern channels

The conspiracy endures because it recycles classic antisemitic tropes—secret cabals, dual loyalties and territorial usurpation—and because it can be adapted to new political scares, local fires or immigration anxieties; fringe media, nationalist commentators and even some politicians have revived or hinted at the theme in crises, amplifying rumor into public debate despite official and scholarly rejection [7] [4] [8]. The pattern mirrors broader dynamics seen with other persistent conspiracies: selective interpretation of innocuous facts, anecdotal confirmation and the exploitation of institutional distrust to sustain belief [9] [10].

5. Real harms and why debunking matters

Beyond being historically false, the Andinia narrative has tangible consequences: it has been invoked to justify surveillance, discrimination and hostility toward Jewish communities in Argentina and Chile, and it served as interrogation fodder under repressive regimes—demonstrating how a baseless myth can underpin persecution and political scapegoating [5] [4]. Civil‑society groups that track antisemitism warn that the theory is a modern echo of fabricated texts like The Protocols of the Elders of Zion and stresses that debunking reduces the exploitability of the story [4].

6. Bottom line: history untangled from paranoia

The historical kernels cited by believers—Jewish immigration, agricultural colonization proposals and tourist patterns—are real but do not amount to a secret secessionist plan for Patagonia; repeated reviews by historians, journalists and watchdogs find no documentary or material evidence supporting the Andinia Plan and frame it instead as an antisemitic conspiracy deployed for political ends [6] [1] [3]. Where sources are silent on specific operational details or classified archives, reporting admits those limits rather than asserting hidden proof; on the record, the claim remains unsubstantiated and functionally debunked [5].
