In a critical moment in the Iran nuclear negotiations, the top security official is suddenly replaced.

Supreme Leader Mojtaba appoints Zolagar Del as a political adviser, while Rezaei takes over as secretary of the Supreme National Security Council and also serves as the Leader’s representative.

Both are hardliners, and both have previously headed the Revolutionary Guards.

At this moment, Iran is at a diplomatic make-or-break stage in reaching an agreement to reopen the Strait of Hormuz.

Some political figures say that Zolagar Del’s resignation is not related to security issues; the conditions for reopening the strait that he had previously proposed align with Mojtaba’s views.

After the personnel change, how will Tehran’s position change?

No one can say for sure.
