Background: The JFK Assassination and Sweden’s Cold War Context

The assassination of John F. Kennedy remains one of the most debated events of the 20th century. The Warren Commission concluded that Lee Harvey Oswald acted alone, but conspiracy theories involving the CIA, the mafia, and foreign actors like the Soviet Union and Cuba have persisted. The latest declassified documents continue to fuel this debate, even though they provide no definitive proof of a conspiracy.

For Sweden, these documents are more than a historical curiosity. They reflect a time when the Cold War shaped global security policies—including Sweden's.

Swedish Neutrality During the Cold War – In Theory and Practice

Sweden was officially neutral, but in practice, the country carefully balanced between East and West. The Soviet Union's presence in the Baltic Sea and submarine incidents in the 1980s showed that Sweden was not insulated from superpower conflicts. At the same time, Sweden maintained secret ties with the West, including the U.S. and NATO, as later research revealed. The JFK documents may offer insight into how Sweden was perceived—and perhaps even monitored—by American intelligence, a perspective especially relevant to Swedish readers.

What Do the New Documents Reveal?

The ten documents analyzed here do not directly address the Kennedy assassination but focus on CIA agents and their skills during the 1950s and 1960s. Surprisingly, they contain specific references to Sweden.

For example, document 104-10224-10012 mentions an agent named J. Wigren, described as highly proficient in Russian and knowledgeable about Swedish political parties. Why would a CIA agent need insight into Swedish politics during the Cold War?

Sweden as an Intelligence Focal Point

Sweden’s proximity to the Soviet Union and its advanced industry made it a point of interest for both blocs. The presence of CIA agents with expertise in Swedish affairs suggests Sweden wasn’t as invisible to U.S. intelligence as often assumed.

The documents also showcase the CIA’s wide linguistic reach—agents fluent in Russian, French, Hindi, and even cryptic references in Arabic and Cyrillic. This mirrors Sweden’s own intelligence agencies, like Säpo and FRA, which invested in language skills to monitor Eastern threats.

Swedish Parallels to CIA Surveillance

A key focus of the JFK files is the CIA's surveillance of Lee Harvey Oswald, especially his 1963 trip to Mexico City where he contacted Soviet and Cuban embassies. While the documents in this analysis don't directly mention Oswald, other files show the CIA tracked his movements in detail.

There’s a direct Swedish parallel in Säpo’s monitoring of suspected Soviet agents. A prime example is the Wennerström affair in 1963, where Colonel Stig Wennerström was exposed as a Soviet spy. Like the CIA tracked Oswald due to his Soviet ties, Säpo followed individuals seen as threats to national security.

The CIA’s Interest in Sweden – What Does It Tell Us?

Perhaps the most intriguing detail for a Swedish audience is the mention of Swedish political parties. During the Cold War, Sweden’s political scene was dominated by the Social Democrats, with center-right parties often viewed as more pro-Western. Communist groups were closely watched by Säpo due to suspected Soviet ties.

The fact that CIA agents had knowledge of these parties suggests a deliberate effort to map Sweden’s political stability and potential role in a deepening Cold War.

Secret Cooperation Despite Neutrality

This isn’t the first time Sweden appears in U.S. intelligence contexts. Research has shown covert cooperation with NATO and the U.S., especially in signals intelligence. The IB affair in the 1970s revealed Sweden's surveillance of left-wing groups and data sharing with the West.

CIA interest in Sweden, hinted at in the JFK files, fits into a broader strategy to understand and influence the Nordic region—where Sweden, with its strategic location, was key despite its neutral stance.

Linguistic Expertise – A Shared Strategy

The CIA’s emphasis on language skills is particularly resonant in Swedish history. Agent Wigren’s Russian proficiency mirrors Swedish efforts to train experts in Eastern European languages. FRA recruited linguists to intercept Soviet communications, and universities like Uppsala and Lund became hubs for Slavic studies.

Both the U.S. and Sweden recognized that understanding the enemy was vital in the information war.

Cryptic Codenames and Swedish Counterparts

Terms like “Liebeny” and “FIRGITTEA” in the CIA documents spark curiosity. These may have been internal codenames—just like Sweden used its own secret codes. FRA’s sophisticated codebreaking played a critical role during the 1980s submarine hunts. For Swedish readers, it raises the question: what secrets still lie dormant in our own archives?

A Critical Swedish Eye on Official Narratives

The official story that Oswald acted alone has always been controversial. Similarly, Sweden’s self-image of neutrality has been challenged by revelations of secret deals and surveillance.

It's natural for a Swedish audience to approach the JFK files critically—just as we re-examine our own Cold War history. Could still-classified Swedish documents offer new insights into global events like the Kennedy assassination?

Swedish Relevance and Future Questions

The JFK files are a reminder that Sweden was not an isolated island during the Cold War. CIA interest in Swedish politics and the parallels to Säpo’s surveillance show that Sweden was part of a global intelligence network.

This could open new discussions about Sweden’s role in that era—how much did the CIA know about us, and what did we know about them?

Moreover, while the U.S. gradually releases its JFK records, much of Sweden’s Cold War past remains classified. A full release of Säpo or FRA documents could reveal more about Sweden’s cooperation with the CIA and its own surveillance efforts.

Conclusion: Sweden in the Shadows of the JFK Files

The newly released JFK files from March 2025 don’t solve the mystery of Kennedy’s death—but they offer a fascinating look into CIA operations, including surprising insights into Sweden.

Through references to Swedish political parties and intelligence parallels, they show how the Cold War reached even a neutral country. For Swedish readers, this is a chance to reflect on our role in a tense global era—and to ask what secrets still lie in our own archives. The JFK files are not just an American story—they remind us that the Cold War cast its shadow over Sweden too.
