Snowden disclosures

7 min read

In June 2013, a young American contractor downloaded the contents of his security clearance onto a USB drive, walked out of a government facility in Hawaii, and ignited a scandal that would reverberate through capitals around the world. Edward Snowden had just executed what a former British intelligence chief called "the most catastrophic loss to British intelligence ever"—and in doing so, he pulled back the curtain on an unprecedented global surveillance apparatus that spanning from Washington to Berlin, from Ottawa to Canberra, from Stockholm to Tel Aviv.

The documents Snowden carried would eventually implicate some of America's closest allies in a sprawling network of international espionage—one built not on the rubble of mutual suspicion but on secret treaties and raw data-sharing agreements that had been cultivated for decades. The disclosures would reshape conversations about privacy, power, and the boundaries of democratic oversight from Washington to Moscow.

The Man Who Walked Away

Edward Joseph Snowden was a former NSA contractor working for Booz Allen Hamilton, one of the largest defense and intelligence contractors in the United States. In his twenties, he held technical positions at the CIA and had been employed by the NSA itself. He was granted access to documents belonging not only to the U.S. government but also to several allied governments through what is known as the Five Eyes network—an exclusive intelligence-sharing arrangement between the United States, Britain, Canada, Australia, and New Zealand.

When Snowden left the NSA facility in Hawaii that June morning in 2013, he carried with him an estimated cache of documents whose precise scope remains unknown—but government officials have offered some figures. The Pentagon assessed this as "the biggest theft of U.S. secrets in history." British officials claimed at least 58,000 intelligence files had been compromised; Australian officials said at least 15,000 Australian intelligence files were exposed; and the U.S. Department of Defense estimated roughly 1.7 million U.S. intelligence files potentially involved. The actual numbers remain contested.

Snowden's motivations were clear from his earliest public statements: he wanted the public to understand what had been built in their name—but without adequate consent or democratic accountability.

"The reason for the Snowden disclosures was simple: the surveillance programs were sweeping up far more information about ordinary citizens than any reasonable definition of 'national security' could justify. The NSA wasn't just targeting terrorists—it was capturing the phone records, internet activity, and location data of entire populations."

A Global Surveillance Network Exposed

The first documents were published simultaneously in June 2013 by The Washington Post and The Guardian—two papers on opposite sides of the Atlantic that would soon find themselves at the center of a global controversy. Over the weeks and months that followed, journalists from around the world would receive portions of Snowden's cache.

What emerged was nothing short of revelatory.

The documents revealed secret agreements between members of the UKUSA community—Britain, the United States, Canada, Australia, and New Zealand—that enabled a level of cooperation previously unknown to most publics. But beyond the Five Eyes arrangement lay deeper treaties with other nations that made the surveillance truly global.

German Federal Intelligence service, known as the BND, was revealed to be transferring massive amounts of intercepted data to the NSA. Swedish Television revealed that the National Defence Radio Establishment—known as FRA—had provided the NSA with data from cable collection under a secret agreement signed in 1954 for bilateral cooperation on surveillance. These arrangements had persisted for decades, buried beneath layers of diplomatic agreements and classified protocols.

The scope was staggering:

Australian Secret Service (ASD), British GCHQ, Canadian CSE, Danish PET, French DGSE, German BND, Italian AISE, Japanese DIH, Dutch AIVD, Norwegian NIS, Spanish CNI, Swiss NDB—Singapore's SID—and Israel (ISNU), which received raw, unfiltered data of U.S. citizens from the NSA directly.

The New York Times later summarized what they called "a global surveillance system that cast off many of its historical restraints after the attacks of September 11, 2001." Secret legal authorities empowered the NSA to sweep in telephone records, internet metadata, and location data of entire populations. The agency had undisclosed financial relationships with numerous commercial partners and telecommunications companies—and previously secret relationships with allied governments for sharing intercepted data on each other's citizens.

The Guardian's editor Alan Rusbridger would later say: "We have published I think 26 documents so far out of the 58,000 we've seen." The actual extent remains difficult to gauge.

The Legal Firestorm

On June 14, 2013—shortly after the first publications—the United States Department of Justice charged Edward Snowden with espionage and theft of government property. The charges marked the beginning of a legal odyssey that would span continents and legal traditions.

By late July 2013, Russia granted Snowden temporary asylum for one year—an act that contributed to what was described as deterioration in Russia-United States relations. In October 2013, British Prime Minister David Cameron threatened to issue a D-Notice—a formal warning—after The Guardian published damaging intelligence leaks. By November, Britain's Metropolitan Police Service had opened a criminal investigation into the disclosures.

The disclosures also reached Brazil: O Globo revealed details about programs operating in that country. In the United States, President Barack Obama addressed the matter in January 2014:

"the sensational way in which these disclosures have come out has often shed more heat than light"

Critics like historian Sean Wilentz noted that many of Snowden's documents did not concern domestic surveillance directly—but rather international espionage. The question of whether the public was responsibly informed remained disputed.

Media Coverage Around the World

The simultaneous publication represented only a small portion of what Snowden had obtained—but it triggered what would become one of the most significant investigative journalism efforts in history.

These outlets accessed portions of Snowden's cache:

The Guardian and The Washington Post published first, then The New York Times entered the conversation. Canadian Broadcasting Corporation and Australian Broadcasting Corporation brought the story to North American and southern hemisphere audiences. Der Spiegel covered Germany; Le Monde France; L'Espresso Italy; NRC Handelsblad handled Netherlands; Dagbladet Norway; El País Spain; Sveriges Television Sweden.

Brazilian outlet O Globo also contributed significantly, bringing attention to programs in Latin America.

The Guardian editor Alan Rusbridger estimated that out of 58,000 documents seen by journalists, only about 26 had been published as of December 2013. The rest remained in legal limbo—subjects of ongoing negotiations between news organizations and governments worldwide.

The Fallout

George Brandis, Australia's Attorney-General, offered perhaps the most stark assessment: that Snowden's disclosure was "the most serious setback for Western intelligence since the Second World War." That sentiment echoed through allied capitals as officials scrambled to assess exactly what had been exposed—and what remained vulnerable.

But there were revelations beyond the obvious. The NSA was receiving data directly from telecommunications companies—some operated under code names like Artifice (Verizon), Lithium (AT&T), Serenade, SteelKnight, and X. These relationships had been hidden behind layers of classified arrangements that prevented even Snowden—despite his clearance—from knowing who owned these operations.

The Pentagon's first assessment concluded this was "the biggest theft" in the history of American secrets. Sir David Omand, former director of GCHQ, called it "the most catastrophic loss to British intelligence ever."

The Conversation Continues

As 2013 turned toward winter with Snowden still in Moscow—his lawyer said he had pledged not to release any documents while staying in Russia—the question remained: what else was there?

The documents revealed that before the Snowden disclosures, the global surveillance apparatus had been exposed piece by piece through individuals like NSA analyst Perry Fellwock (under pseudonym "Winslow Peck") who revealed the existence of the UKUSA Agreement—forming the basis for what's known as the ECHELON network. In 1988, that network's existence was confirmed by Lockheed employee Margaret Newsham.

Months before September 11 and during its aftermath, further details were provided by former MI5 official David Shayler and journalist James Bamford. GCHQ employees like Katharine Gun revealed plots to bug UN delegates shortly before the Iraq War. British Cabinet Minister Clare Short revealed in 2004 that the UK had spied on UN Secretary-General Kofi Annan.

But Snowden's documents were different—they were complete. They laid out not individual programs but an entire architecture of global surveillance, built upon secret treaties and shared data between nations whose citizens had no idea they were being watched.
