On Tuesday, September 11, the Guardian published a previously undisclosed document which revealed top-secret policies in place since 2009 that are used to share personal phone and Internet data pertaining to United States citizens with American ally Israel.
The document, a five-page memorandum authorized by the National Security Agency near the beginning of US President Barack Obama’s first administration, outlines a deal between the NSA and Israel’s SIGINT National Unit, or ISNU.
