美国被爆曾监听35个外国领导人

The memo, dated October 2006 and which was issued to staff in the agency's Signals Intelligence Directorate (SID), was titled "Customers Can Help SID Obtain Targetable Phone Numbers".

It begins by setting out an example of how US officials who mixed with world leaders and politicians could help agency surveillance.

"In one recent case," the memo notes, "a US official provided NSA with 200 phone numbers to 35 world leaders … Despite the fact that the majority is probably available via open source, the PCs [intelligence production centers] have noted 43 previously unknown phone numbers. These numbers plus several others have been tasked."

The document continues by saying the new phone numbers had helped the agency discover still more new contact details to add to their monitoring: "These numbers have provided lead information to other numbers that have subsequently been tasked."

But the memo acknowledges that eavesdropping on the numbers had produced "little reportable intelligence". In the wake of the Merkel row, the US is facing growing international criticism that any intelligence benefit from spying on friendly governments is far outweighed by the potential diplomatic damage.

The memo then asks analysts to think about any customers they currently serve who might similarly be happy to turn over details of their contacts.

"This success leads S2 [signals intelligence] to wonder if there are NSA liaisons whose supported customers may be willing to share their 'Rolodexes' or phone lists with NSA as potential sources of intelligence," it states. "S2 welcomes such information!"
