US intelligence spent years spying on European targets from a secretive base. Now, it seems that German intelligence was aware of the espionage -- and did nothing to stop it.
It was obvious from its construction speed just how important the new site in Bavaria was to the Americans. Only four-and-a-half months after it was begun, the new, surveillance-proof building at the Mangfall Kaserne in Bad Aibling was finished. The structure had a metal exterior and no windows, which led to its derogatory nickname among members of the Bundesnachrichtendienst (BND), the German foreign intelligence agency: The "tin can."
The construction project was an expression of an especially close and trusting cooperation between the American National Security Agency (NSA) and the BND. Bad Aibling had formerly been a base for US espionage before it was officially turned over to the BND in 2004. But the "tin can" was built after the handover took place.
The heads of the two intelligence agencies had agreed to continue cooperating there in secret. Together, they established joint working groups, one for the acquisition of data, called Joint Sigint Activity, and one for the analysis of that data, known as the Joint Analysis Center.
But the Germans were apparently not supposed to know everything their partners in the "tin can" were doing. The Americans weren't just interested in terrorism; they also used their technical abilities to spy on companies and agencies in Western Europe. They didn't even shy away from pursuing German targets.
The Germans noticed -- in 2008, if not sooner. But nothing was done about it until 2013, when an analysis triggered by whistleblower Edward Snowden's leaks showed that the US was using the facility to spy on German and Western European targets.
On Thursday, though, SPIEGEL ONLINE revealed that the US spying was vastly more extensive than first thought. The revelations have been met with extreme concern in the German capital -- partly because they mark the return of a scandal that two successive Merkel administrations have never truly sought to clear up.
It remains unclear how much the BND knew, and to what extent German intelligence was involved, either intentionally or not. More crucially, it demonstrates the gap in trust that exists between two close allies.
