The NSA supposedly protects the USA from its enemies. Instead, its been spying on Germany, a close US ally, for decades:
The US National Security Agency tapped phone calls involving German chancellor Angela Merkel and her closest advisers for years and spied on the staff of her predecessors, according to WikiLeaks.
A report released by the group on Wednesday suggested NSA spying on Merkel and her staff had gone on far longer and more widely than previously realised. WikiLeaks said the NSA targeted 125 phone numbers of top German officials for long-term surveillance .

WikiLeaks published what it said were three NSA intercepts of Merkel’s conversations, and data it said listed telephone numbers for the chancellor, her aides, her office and even her fax machine.
“The names associated with some of the targets indicate that spying on the Chancellery predates Angela Merkel as it includes staff of former Chancellor Gerhard Schroeder (in office 1998-2002), and his predecessor Helmut Kohl,” WikiLeaks added in a statement.
Barack Obama recently called Germany an "inseparable" ally. The actions of his spy agency may be about to test that - because nobody likes it when a supposed friend is just a two-faced spy.
