Snowden files: US spooks share secret data
The National Security Agency (NSA) routinely shares raw intelligence data with Israel without first sifting it to remove information about United States citizens, a top-secret document provided to the Guardian by whistle-blower Edward Snowden reveals.
Details of the intelligence-sharing agreement are laid out in a memorandum of understanding between the NSA and its Israeli counterpart that shows the US government handed over intercepted communications likely to contain the phone calls and emails of American citizens. The agreement places no legally binding limits on the use of the data by the Israelis.
The disclosure that the NSA agreed to provide raw intelligence data to a foreign country contrasts with assurances from the Obama administration that there are rigorous safeguards to protect the privacy of US citizens caught in the dragnet. The intelligence community calls this process "minimisation", but the memorandum makes clear that the information shared with the Israelis would be in its pre-minimised state.
The deal was reached in principle in March 2009, according to the undated memorandum, which lays out the ground rules for the intelligence sharing.
The five-page memorandum, termed an agreement between the US and Israeli intelligence agencies "pertaining to the protection of US persons", repeatedly stresses the constitutional rights of Americans to privacy and the need for Israeli intelligence staff to respect these rights.
But this is undermined by the disclosure that Israel is allowed to receive "raw Sigint" – signal intelligence.
The memorandum says: "Raw Sigint includes, but is not limited to, unevaluated and unminimized transcripts, gists, facsimiles, telex, voice and Digital Network Intelligence metadata and content."
According to the agreement, the intelligence being shared would not be filtered in advance by NSA analysts to remove US communications. "NSA routinely sends ISNU [the Israeli Sigint National Unit] minimised and unminimized raw collection," it says.
Although the memorandum is explicit in saying the material had to be handled in accordance with US law, and that the Israelis agreed not to target Americans identified in the data deliberately, these rules are not backed up by legal obligations.
"This agreement is not intended to create any legally enforceable rights and shall not be construed to be either an international agreement or a legally binding instrument according to international law," it says.
In a statement to the Guardian, an NSA spokesperson did not deny that personal data about Americans was included in raw intelligence data shared with the Israelis.
But the agency insisted that the shared intelligence complied with all rules governing privacy.
"Any US person information that is acquired as a result of NSA's surveillance activities is handled under procedures that are designed to protect privacy rights."
The NSA declined to answer specific questions about the agreement, including whether permission had been sought from the Foreign Intelligence Surveillance court for handing over such material. The memorandum of understanding, which the Guardian is publishing in full, allows Israel to retain "any files containing the identities of US persons" for up to a year. The agreement requests only that the Israelis should consult the NSA's special liaison adviser when such data is found.
Notably, a much stricter rule was set for US government communications found in the raw intelligence. The Israelis were required to "destroy upon recognition" any communication "that is either to or from an official of the US government".
Such communications included those of "officials of the executive branch (including the White House, Cabinet departments, and independent agencies), the US House of Representatives and Senate (member and staff) and the US federal court system (including, but not limited to, the supreme court)". – © Guardian News & Media 2013
