Soviet Bloc Plots to Coerce Four Nations While Cuba Defies Nuclear Treaty
By Roy Castellano ·
Cuba refused to sign the Non-Proliferation Treaty to counter the US presence at Guantanamo while Soviet leaders plotted to coerce Argentina and Brazil into accession.
In mid-August 1978, representatives of the socialist countries gathered in East Berlin to synchronize their movements for the upcoming 22nd general conference of the International Atomic Energy Agency (IAEA). The objective was a unified front. The record of this meeting survives in a report sent by Dr. György Osztrovszki, vice-chairman of the Hungarian National Atomic Energy Commission, to Comrade Komives of the Hungarian Foreign Ministry.
According to the English translation of this document provided by the Cold War International History Project, the meeting took place from August 15 to 17. The IAEA, as established in the public record, is an autonomous organization within the United Nations system designed to promote the peaceful use of nuclear energy while inhibiting its use for military purposes. For the socialist bloc, the 1978 conference was not merely a technical summit but a venue to assert a specific "political line."
August 15-17, 1978
The Soviet delegation took the lead in East Berlin, arguing that the socialist states should leverage resolutions adopted by the UN meeting on disarmament. The goal was to use these "positive resolutions" to reinforce the safeguards system and the Non-Proliferation Treaty (NPT). The Soviets viewed the IAEA conference as a tool for diplomatic coercion, urging the socialist countries to call upon those who had not yet signed the NPT to do so immediately.
The strategy focused on two categories of holdouts. First were those the Soviets identified as possessing "an actual nuclear potential," specifically Argentina, Brazil, India, and Pakistan. Second were nations situated in "zones of [international] tension," a list that included Zaire, Egypt, and South Africa. By pushing these nations toward the NPT, the Soviet bloc sought to codify a global order where nuclear capability remained the exclusive province of a few, while the rest were bound by strict safeguards.
"Actual Nuclear Potential"
While the Soviet Union sought a broad application of the NPT, the meeting also highlighted the friction and particularities of its satellite and partner states. The delegation from the Democratic People's Republic of Korea (DPRK) proposed a more aggressive diplomatic offensive. The DPRK announced its intention to deliver a speech at the general conference opposing the approval of the mandates of South Korea, Chile, and South Africa.
Romania and Cuba agreed with the North Korean position. The Soviet side, however, was more selective in its support. The Soviets announced they would speak against the mandates of South Korea and Chile, but they stopped short of fully adopting the North Korean line on South Africa, stating instead that they would "give support to the Korean proposal" regarding the South African case. This nuance suggests a Soviet desire to maintain a degree of diplomatic flexibility even while managing the more volatile instincts of its allies in Pyongyang.
Guantanamo and the NPT
One of the most significant points of contention involved technical assistance. The delegations generally agreed that member states of the NPT—those committed to the "exclusively peaceful use" of nuclear energy—should be given preference when receiving technical aid. This was a move to weaponize IAEA assistance, using it as a carrot to induce NPT accession.
Cuba, however, broke ranks. The Cuban representative stated that his country disagreed with the declaration of this principle. The reasoning was based on a "special situation": the immediate vicinity of the United States and the presence of an American military base at Guantanamo. Because of these factors, Cuba claimed it "could not afford to sign the Non-Proliferation Treaty."
This admission reveals a paradox within the socialist bloc's strategy. While the Soviets pushed for a universal safeguards system to constrain rivals like Brazil or India, they had to accommodate a key ally that felt it could not submit to those same rules without compromising its security against the United States. Cuba wanted the benefits of the IAEA's technical assistance without the constraints of the NPT.
Related records on the agency's operations during this era are held in the US National Archives under "Subject Files on the International Atomic Energy Agency" and "International Atomic Energy Agency Program Files," and within the State Department's FRUS volumes on the regulation of armaments from 1955 to 1968. However, those records do not provide the internal socialist perspective captured in the Osztrovszki report.
The report ends without detailing the outcome of the 22nd general conference. It remains an open question whether the Cuban dissent altered the final resolution on technical assistance, or if the Soviet-backed push against the mandates of Chile and South Korea succeeded in the plenary session.
