Episode notes
Strait Of Hormuz Is The Central Battleground
- The Iran war has become chiefly about control of the Strait of Hormuz, where threats and attacks have created a de facto closure of a waterway that once carried ~15% of global oil.
- Gregg Carlstrom explains Iran's limited attacks and geography mean persistent threats scare off shippers and insurers, keeping flows halted without a formal blockade.
Small Attacks Can Keep The Strait Shut
- A few intermittent attacks are enough to maintain a de facto closure because insurers and shippers avoid transit after even occasional strikes.
- The strait's 54-kilometre narrowness and mountainous Iranian coast mean naval escorts have only seconds to react to strikes.
Seizing Khark Island Carries High Risks
- U.S. consideration of seizing Khark Island illustrates risky escalation: taking it is feasible, but holding it exposes troops to mainland missile and drone fire and may backfire economically.
- Gregg Carlstrom notes strikes hit Iranian military positions there while leaving the oil terminal intact, suggesting softening up for a possible seizure.
