Spies that are not loved by other spies

Jeff Stein of the Washington Post writes:
The CIA took an internal poll not long ago about friendly foreign intelligence agencies.
The question, mostly directed to employees of the clandestine service branch, was: Which are the best allies among friendly spy services, in terms of liaison with the CIA, and which are the worst? In other words, who acts like, well, friends?
“Israel came in dead last,” a recently retired CIA official told me the other day.
Not only that, he added, throwing up his hands and rising from his chair, “the Israelis are number three, with China number one and Russia number two,” in terms of how aggressive they are in their operations on U.S. soil.

As tensions with Iran escalate, according to former CIA officer Philip Giraldi, “Israeli agents have become more aggressive in targeting Muslims living in the United States as well as in operating against critics.”
“There have been a number of cases reported to the FBI about Mossad officers who have approached leaders in Arab-American communities and have falsely represented themselves as ‘U.S. intelligence,’ ” Giraldi wrote recently in American Conservative magazine.

Giraldi’s piece continued, “Mossad officers sought to recruit Arab-Americans as sources willing to inform on their associates and neighbors. The approaches, which took place in New York and New Jersey, were reportedly handled clumsily, making the targets of the operation suspicious.”
“These Arab-Americans turned down the requests for cooperation,” Giraldi added,”and some of the contacts were eventually reported to the FBI, which has determined that at least two of the Mossad officers are, ironically, Israeli Arabs operating out of Israel’s mission to the United Nations in New York under cover as consular assistants.”
