Argentina, like its neighbor, Brazil, was determined to develop an “independent nuclear fuel cycle,” with the capacity to reprocess plutonium and enrich uranium. Also like Brazil, Argentina was one of the few Latin American countries to refuse to sign the Nuclear Nonproliferation Treaty. Thus, Argentina’s nuclear activities were under routine scrutiny to see if they involved anything that suggested an interest in a weapons capability. US intelligence agencies continued to monitor developments but perspectives shifted as Argentina’s domestic politics evolved. Prepared after the Argentine-British conflict over the Falklands Islands, in which Washington helped London, this special estimate professed “great uncertainty” over Argentina’s nuclear intentions. While “emotionally” the Argentine military leadership was interested in a weapons option, it had “reduced capability to fulfill this desire.”
