The document is undated, but states that the countries agreed to the intelligence-sharing in March 2009.
According to the memo, the raw intelligence "includes, but is not limited to, unevaluated and unminimized transcripts, gists, facsimiles, telex, voice and Digital Network Intelligence (DNI) metadata and content."
The document instructs the Israeli intelligence agency to "strictly limit" access to the NSA data and to only share the data within the Israeli government in a way that protects the identity of U.S. people. Israel is also required to immediately destroy any communications of U.S. government officials.
An NSA spokeswoman declined to address any specific intelligence agreement but argued that coordinating with foreign agencies "mutually strengthens the security of both nations."
"NSA cannot, however, use these relationships to circumvent U.S. legal restrictions. Whenever we share intelligence information, we comply with all applicable rules, including the rules to protect U.S. person information," the NSA official said. "Any U.S. person information that is acquired as a result of NSA’s surveillance activities is handled under procedures that are designed to protect privacy rights."
