Pakistan is described in detail as an “intractable target,” and counterintelligence operations “are strategically focused against [the] priority targets of China, Russia, Iran, Cuba and Israel.”
In addition to what the former U.S. officials described as intrusions in homes in the past decade, Israel has been implicated in U.S. criminal espionage cases and disciplinary proceedings against CIA officers and blamed in the presumed death of an important spy in Syria for the CIA during the administration of President George W. Bush.
The CIA considers Israel its No. 1 counterintelligence threat in the agency's Near East Division, the group that oversees spying across the Middle East, according to current and former officials. Counterintelligence is the art of protecting national secrets from spies. This means the CIA believes that U.S. national secrets are safer from other Middle Eastern governments than from Israel. […]
The National Security Agency historically has kept tabs on Israel. The U.S., for instance, does not want to be caught off guard if Israel launches a surprise attack that could plunge the region into war and jeopardize oil supplies, putting American soldiers at risk.
Matthew Aid, the author of "The Secret Sentry," about the NSA, said the U.S. started spying on Israel even before the state was created in 1948. Aid said the U.S. had a station on Cyprus dedicated to spying on Israel until 1974. Today, teams of Hebrew linguists are stationed at Fort Meade, Md., at the NSA, listening to intercepts of Israeli communications, he said.
