Two weeks after Edward Snowden’s first revelations about sweeping government surveillance, President Obama shot back. “We know of at least 50 threats that have been averted because of this information not just in the United States, but, in some cases, threats here in Germany,” Obama said during a visit to Berlin in June. “So lives have been saved.”
In the months since, intelligence officials, media outlets, and members of Congress from both parties all repeated versions of the claim that NSA surveillance has stopped more than 50 terrorist attacks. The figure has become a key talking point in the debate around the spying programs.
“Fifty-four times this and the other program stopped and thwarted terrorist attacks both here and in Europe — saving real lives,” Rep. Mike Rogers, a Michigan Republican who chairs the House Intelligence Committee, said on the House floor in July, referring to programs authorized by a pair of post-9/11 laws. “This isn’t a game. This is real.”
But there’s no evidence that the oft-cited figure is accurate.
The NSA itself has been inconsistent on how many plots it has helped prevent and what role the surveillance programs played. The agency has often made hedged statements that avoid any sweeping assertions about attacks thwarted.
A chart declassified by the agency in July, for example, says that intelligence from the programs on 54 occasions “has contributed to the [U.S. government’s] understanding of terrorism activities and, in many cases, has enabled the disruption of potential terrorist events at home and abroad” — a much different claim than asserting that the programs have been responsible for thwarting 54 attacks.
NSA officials have mostly repeated versions of this wording.
When NSA chief Gen. Keith Alexander spoke at a Las Vegas security conference in July, for instance, he referred to “54 different terrorist-related activities,” 42 of which were plots and 12 of which were cases in which individuals provided “material support” to terrorism.
But the NSA has not always been so careful.
During Alexander’s speech in Las Vegas, a slide in an accompanying slideshow read simply “54 ATTACKS THWARTED.”
And in a recent letter to NSA employees, Alexander and John Inglis, the NSA’s deputy director, wrote that the agency has “contributed to keeping the U.S. and its allies safe from 54 terrorist plots.” (The letter was obtained by reporter Kevin Gosztola from a source with ties to the intelligence community. The NSA did not respond when asked to authenticate it.)
Asked for clarification of the surveillance programs’ record, the NSA declined to comment.
