IT IS ONE of the world’s most powerful alliances. And yet most people have probably never heard of it, because its existence is a closely guarded government secret.The “SIGINT Seniors” is a spy agency coalition that meets annually to collaborate on global security issues. It has two divisions, each focusing on different parts of the world: SIGINT Seniors Europe and SIGINT Seniors Pacific. Both are led by the U.S. National Security Agency, and together they include representatives from at least 17 other countries. Members of the group are from spy agencies that eavesdrop on communications – a practice known as “signals intelligence,” or SIGINT.
Details about the meetings of the SIGINT Seniors are disclosed in a batch of classified documents from the NSA’s internal newsletter SIDToday, provided by whistleblower Edward Snowden and published today by The Intercept. The documents shine light on the secret history of the coalition, the issues that the participating agencies have focused on in recent years, and the systems that allow allied countries to share sensitive surveillance data with each other.
The SIGINT Seniors Europe was formed in 1982, amid the Cold War. Back then, the alliance had nine members, whose primary focus was on uncovering information about the Soviet Union’s military. Following the attacks on the U.S. in September 2001, the group grew to 14 and began focusing its efforts on counterterrorism.
The core participants of the Seniors Europe are the surveillance agencies from the so-called Five Eyes: the NSA and its counterparts from the U.K., Australia, Canada, and New Zealand. As of April 2013, the other members were intelligence agencies from Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, and Sweden.
