The surveillance-sharing relationship with Israel has expanded to include the NSA’s British and Canadian counterparts, GCHQ and CSEC, both of which actively participate in feeding the Israelis selected communications data they have collected. Several documents from early 2009, at the height of the Israeli attack on Gaza called “Cast Lead” that left more than 1,000 people dead, detail some of this cooperation.
One top secret 2009 GCHQ project named “YESTERNIGHT” involved “Ruffle,” the British agency’s code name for ISNU. According to the document, the project involved a “trilateral (GCHQ, NSA and Third Party RUFFLE) targeting exchange agreement covering respective COMSAT accesses.” One of the “specific intelligence topics” shared between the parties was “Palestinians”, although the GCHQ document states that “due to the sensitivities” of Israeli involvement, that particular program does not include direct targeting of Palestinians and Israelis themselves. Another GCHQ document from February, 2009, describes “a quadrilateral meeting for RUFFLE, NSA, CSEC and GCHQ.”
The British agency noted in early 2009 that it had been spying on emails and telephone numbers specifically requested by ISNU, “and they have thanked us many times over.”
If they're doing this spying now, then that makes them complicit in the war crimes Israel is currently committing in Gaza.
And then there's the obvious question: is the GCSB also spying for Israel? If they were, I don't think most kiwis would approve...
