This is really Professor Juneau’s area of expertise. I’ll let him complete what I’m about to say, and I’ll speak subject to his authority.
You’re quite right. The Iranian regime’s activities, in general, respond to a clear principle: to create disorder and instability. This includes the activities of its cyber-army, its propaganda activities and what it’s doing in Lebanon and Yemen. As you know, the IRGC Quds Force is active in Sudan, where it supplies Shahed‑136 drones to the army of the general whose name escapes me, but whose aim is precisely to gain a foothold on both sides of the Bab el‑Mandab Strait and the Red Sea and destabilize, if not disrupt, world trade and shipping.
