That article had some interesting information:
What neither side knew was that there was a spy in the summit. Iran’s MOIS, a rival of the Revolutionary Guards within the Iranian national security apparatus, secretly had an agent in the meeting who reported everything that was discussed. The MOIS agent not only attended but “acted as coordinator of this meeting,” according to the MOIS cable. The MOIS envied the Revolutionary Guards’ power and influence and secretly tried to keep track of the Guards’ activities around the world, the leaked archive shows.
Is MOIS working with Trump/Q?
