Over the last decade, the NSA has significantly increased the surveillance assistance it provides to its Israeli counterpart, the Israeli SIGINT National Unit (ISNU; also known as Unit 8200), including data used to monitor and target Palestinians. In many cases, the NSA and ISNU work cooperatively with the British and Canadian spy agencies, the GCHQ and CSEC.

The relationship has, on at least one occasion, entailed the covert payment of a large amount of cash to Israeli operatives. Beyond their own surveillance programs, the American and British surveillance agencies rely on U.S.-supported Arab regimes, including the Jordanian monarchy and even the Palestinian Authority Security Forces, to provide vital spying services regarding Palestinian targets.
