If Israel gave us a list with real names then they are huge fools. But the Israelis are smart, they may have given us a list of people that they want the Iranians to believe to be spies. Our allies don’t trust us. They probably assume we’re compromised or will leak what info we have.
I think this whole story is a bunch of hooey. Would the Iranians believe that Mossad gave US intel such a list in the first place? I say no. Maybe I’m completely wrong.
