Yes, ask their Mossad direct and local handlers (as per Mike Pompeo [1]) about how things are going, I’m sure that this being Mossad they have a ground-based way to get the information out.
Mike Pompeo is a private citizen; is there some reason to believe that he has direct knowledge of foreign involvement in these protests? It seems unlikely, and doubly so that he’d actually disclose it if he did.
“Former” is operative. I don’t see any reason to believe that Pompeo has special insider knowledge here, and sharing it makes zero sense even if he did. The more parsimonious explanation is that he’s a sidelined grifter whose only way to stay relevant is to speculate on social media.
After reading Walter Isaacson's biography of US Secretary of State Henry Kissinger, I would be extremely surprised to find that a former Secretary of State was suddenly out of the loop on major events.
Henry Kissinger was a notorious power broker, and basically remained "in the loop" until the day he died. Pompeo is neither of these things.
But there's an even simpler way to reach this conclusion: given everything you and I know about Pompeo's politics, is there any reason to believe he'd want to introduce doubt about the legitimacy of popular protest in Iran?
