A self-proclaimed intelligence expert from Israel by the name of Andy Martin claims that Mr. Cipel was a MOSSAD case officer, originally posted to New York under official cover. Since MOSSAD is well known for using human sex toys, McGreevey could have been lured into a relationship that was intended to penetrate NJ Homeland Security, and possibly national Homeland Security.
And of course, there's the story about a suspected Israeli spy in the Pentagon...
The FBI believes that there is an Israeli spy at the very highest level of the Pentagon; federal agents believe the spy might be or might have been in a position to influence US policy on Iran and Iraq. Of course, the Israeli embassy immediately denied the report.
My guess is that Israel thinks we're not sharing all the info that they need with them.
