Goldman Sachs Exchanges
Host: Alyson Nathan
Date: March 27, 2026
Episode Overview
This episode of Exchanges explores the ongoing Iran conflict, which has now entered its fourth week. Host Alyson Nathan assembles a panel of experts to dissect the motivations behind the war, its likely course, key players, and the global impact—especially on energy markets.
The guests include:
- Sanam Vakil: Director, Middle East & North Africa Program, Chatham House
- Ambassador Dennis Ross: Former Middle East Advisor to five U.S. Administrations
- Vice Admiral Kevin Donegan: Former Commander, U.S. Navy Fifth Fleet
The discussion covers the war’s triggers, Iran’s domestic and strategic objectives, U.S. policy, the pivotal role of the Strait of Hormuz, and the logistical and political challenges around restoring global energy flows.
Key Discussion Points & Insights
1. Iran’s Perspective: Existential Struggle
-
Motivations & Goals
- Iran perceives the conflict as a threat to regime survival and “a regime change war.” Its leadership aims to “spread the costs of the war horizontally and as widely as possible” so that any eventual settlement dissuades future attacks.
- [01:03] Sanam Vakil: “So the system, or what remains of it, is fighting for its very survival...”

-
Perception of Weakness
- The last major conflict (the "12 Day War") left Iran thinking it had conceded too early, fueling external perceptions of Iranian weakness and inviting the current escalation.
- [01:53] Sanam Vakil: “There were perceptions that Iran was weak. And that opened the door… that because Iran was weak, this was the perfect opportunity to go for another round.”

-
US Influence is Limited
- The war’s end is not solely up to the US; Iran seeks a conclusive outcome and, crucially, sanctions relief.
- [04:02] Sanam Vakil: “Ultimately what they really need is sanctions relief... that is going to require some sort of negotiation... nuclear program and ... a broader discussion on regional security.”

2. Military Dynamics: Asymmetry and Stalemate
-
Imbalanced Capabilities
- Iran lags behind the US/Israel militarily, but it uses asymmetric tactics (drones, regional disruption) to inflict damage and prolong conflict.
- [05:12] Sanam Vakil: “Iran has asymmetry in this war, so it can use drones that are low cost to inflict damage.”
- Iran lags behind the US/Israel militarily, but it uses asymmetric tactics (drones, regional disruption) to inflict damage and prolong conflict.
-
No Quick Resolution
- Hopes of regime-changing instability in Iran are unrealistic. The conflict enhances Tehran’s domestic control, exploiting war conditions to suppress dissent.
- [06:23] Sanam Vakil: “Continuing this war allows for a heightened security environment internally... A revolution is very hard to build...”
- Hopes of regime-changing instability in Iran are unrealistic. The conflict enhances Tehran’s domestic control, exploiting war conditions to suppress dissent.
3. The Strait of Hormuz: The Strategic Chokepoint
-
US ‘Victory’ Hindered Without Control of the Strait
- Symbolic or military victories are insufficient if Iran controls the Strait of Hormuz, which is vital for global energy exports.
- [09:29] Amb. Dennis Ross: “He can't end this war with them in that position. Right now, the Iranians’ capacity to threaten hasn't disappeared, but it's been dramatically reduced...”
- Symbolic or military victories are insufficient if Iran controls the Strait of Hormuz, which is vital for global energy exports.
-
Establishing Convoys
- The US and its allies have long-standing plans and annual exercises to ensure passage through the Strait if challenged, but practical flow would be severely limited and not a complete solution.
- [13:03] Vice Adm. Kevin Donegan: “We spend a lot of time planning for a contingency... We've rehearsed this exercise each year for the past 15 years... Yes, France, UK, Greece... Japan, Absolutely. The Koreans. Absolutely.”
- The US and its allies have long-standing plans and annual exercises to ensure passage through the Strait if challenged, but practical flow would be severely limited and not a complete solution.
-
Restoring Normal Oil Flow is Complex
- Even with convoys, restoring the pre-war flow of oil would be slow, mired by insurance and trust issues.
- [15:35] Donegan: “...something like this would never be to replace the flow of oil out of the straits... Maybe 20% of the normal flow... It really depends on what the Iranians start doing after the first one.”
- Even with convoys, restoring the pre-war flow of oil would be slow, mired by insurance and trust issues.
4. Global Players and Mediation Efforts
-
Mediation Only Short-Term Solution
- Without military reversal at the Strait, only robust mediation (possibly involving Russia and China) could break the deadlock, but Iranian leadership fragmentation makes mediation difficult.
- [10:11] Amb. Dennis Ross: “I think then [the war] only resolves soon if there's an effective mediation."
- [11:24] Ross: “I think it comes down to both the Russians and the Chinese…”
- Without military reversal at the Strait, only robust mediation (possibly involving Russia and China) could break the deadlock, but Iranian leadership fragmentation makes mediation difficult.
-
Iranian Leadership Instability
- The death of Ali Laranjani, a key power broker, has left Iran without an authoritative figure to steer negotiations.
- [10:43] Ross: “If anyone was going to be able to orchestrate a move to end the war through mediation, it would have been Laranjani.”
- The death of Ali Laranjani, a key power broker, has left Iran without an authoritative figure to steer negotiations.
5. Iran’s Endgame and the Path Forward
-
Regime Survival Trumps All
- Iran’s leadership is ultimately focused on regime survival, not on controlling the Strait. The war enables them to suppress dissent but leaves the country militarily and economically weakened.
- [16:27] Donegan: “...think about it through the lens that their number one thing is regime survival..."
- Iran’s leadership is ultimately focused on regime survival, not on controlling the Strait. The war enables them to suppress dissent but leaves the country militarily and economically weakened.
-
Economic & Sanctions Pressures Remain
- Post-war, Iran will face an economy in collapse and continued sanctions, making negotiations and “cash infusions” likely top priorities.
-
U.S. Leverage
- The US holds significant leverage: control over Kharg Island, the ability to interdict shadow oil fleets. These could further pressure Tehran in negotiations.
- [17:12] Donegan: “Iran knows that the US holds Kharg island hostage and without car to island flow they can't get anything through... We could also just stop the shadow fleet carriers...”
- The US holds significant leverage: control over Kharg Island, the ability to interdict shadow oil fleets. These could further pressure Tehran in negotiations.
Notable Quotes & Memorable Moments
- [01:03] Sanam Vakil: “This is seen to be a regime change war... the system is fighting for its very survival.”
- [03:01] Vakil on US messaging: “President Trump has shifted the aims and objectives and timelines of this war since it began... the administration has been all over the place.”
- [08:00] Vakil on signs of war ending: “The demands are so out of left field that it's very clear they're not interested in ending this war anytime soon.”
- [09:29] Amb. Dennis Ross: “He can't end this war with them [Iran] in that position [in control of Hormuz].”
- [13:03] Vice Adm. Donegan: “We spend a lot of time planning for a contingency... We've rehearsed this exercise each year for the past 15 years...”
- [15:35] Donegan: “...something like this would never be to replace the flow of oil out of the straits. It can't be done. Maybe 20% of the normal flow.”
- [16:27] Donegan: “Their number one thing is regime survival... when this is over they have an economy that's in collapse...”

Takeaways
- The conflict is likely to drag on, driven by Iran's regime survival instincts and lack of clear “offramps.”
- The Strait of Hormuz remains the critical chokepoint: until full freedom of navigation is restored, energy markets will be jolted.
- Even successful military or logistical operations to reopen the strait would not instantly normalize oil flows; trust and insurance constraints would delay recovery.
- Mediation may offer a diplomatic exit but is hampered by intra-Iranian and great power dynamics.
- Ultimately, economic pressure and postwar reconstruction needs may shape Iran’s willingness to compromise—but that chapter is still ahead.
