This telegram made by the Brazilian Embassy in Buenos Aires, verifies U.S. pressure on Argentina’s nuclear program, especially through Canada, with whom Argentina had a strategic partnership in the nuclear field. The telegram goes into depth on factors that underlie Argentina's decision not to sign the NPT, and its efforts to import the materials necessary for its nuclear program.

This document reveals an encounter between a U.S. State Department official and an Argentine diplomat in Washington D.C., in which the U.S. diplomat suggests to his Argentine counterpart that the U.S. government would warmly welcome an initiative by Argentina and Brazil regarding mutual inspections as well as a declaration renouncing the right to develop peaceful nuclear explosives.

This is a letter written by Brazilian Congressman Herbert Levy which reveals the content of his meetings with high U.S. governmental officials regarding his concern about Argentina’s nuclear activities less than a year after the Falklands/Malvinas War. In these conversations, Levy states that Argentina might develop a nuclear artifact.

Ambassador Barbour reports that Foreign Minister Eban will confer with Deputy Minister of Defense Zvi Dinstein on the location of the Argentine uranium.

Ambassador Barbour spoke to Israeli Foreign Minister Eban, who said he would ask about the location of the Argentine uranium.

The Department of State requested that the Embassy inform the Israelis that they were satisfied with the inspection of Dimona, but ask Israel to clarify the location of the uranium ore from Argentina.

The Embassy did not believe it was advisable to inform the Argentine government of US plans to ask the Israeli government about the location of the uranium.

The Embassy reported that it had no information on Israeli uranium imports, and the only way to obtain that information would be a high-level inquiry to the Israeli Foreign Ministry.

In a conversation with one or two State Department officials, a British Embassy officer notes that reports available to both governments estimate Israel's purchases of uranium to add up to 190 tons and proposed a joint US-British approach to Argentina on safeguards.

In response to a request for further instructions, the Dept. of State informed the Embassy that Washington was looking to establish a common policy on the mandatory application of IAEA safeguards. Until they were closer to agreement, the Embassy should request that the Argentine government apply safeguards to future deals.
