Date: March 19, 2026
Host: Mary Louise Kelly
Guests: Greg Myre (NPR National Security Correspondent – Washington), Arzu Rezvani (NPR Correspondent – Erbil, Iraq)

Brief Overview

This episode delves into the complex and escalating conflict between the US and Iran, with a focus on the situation along the Iran-Iraq border, the diplomatic maneuvering led by President Trump to win allied support, and implications for global security and oil markets. Drawing on firsthand reporting from a key border region and insight from Washington, the NPR team examines the fallout from war, strategic chokepoints like the Strait of Hormuz, and the ongoing struggle to gather information amid internet blackouts and state surveillance inside Iran.

Key Discussion Points & Insights

1. On-the-Ground in Erbil: Fallout from the Iran War

[01:16]

• Why Erbil?

  • Arzu Rezvani explains Erbil’s proximity to both Iran and Turkey and its significance as a US foothold in Iraq, with a large consulate and military base that have been recent targets for Iranian and proxy attacks.
  • "Erbil is a fascinating place because America has a pretty large footprint here ... and you can definitely feel the war in those places." – Arzu Rezvani [01:35]

• Life under War

  • Most drone and interception activity occurs at night, punctuating otherwise “normal” life with sudden bangs that sometimes feel "really close by." [02:35-03:02]

• Attempt to Report from Baghdad

  • Arzu recounts being stopped at a checkpoint when trying to reach Baghdad, with warnings from both Iraqi authorities and the US embassy about kidnappings and ongoing attacks on the massive US embassy.
  • "They took a look at our passports, figured out that we were Americans and advised us to turn around." – Arzu Rezvani [03:36]

• Visit to the Iran-Iraq Border (Haji Amran Crossing)

  • Drones fly low, even over the border, a visible reminder of the war’s reach.
  • Displaced Iranians crossing into Iraq are terrified to speak; one woman emotionally described untenable conditions, only confiding her despair when the microphone was off.
    • "She burst into tears and said that life had become absolutely unbearable between the airstrikes from the sky and Iran's crackdown on the ground." – Arzu Rezvani [05:53]

• Reporting Challenges: Reaching People Inside Iran

  • Hard at the best of times due to Iran’s surveillance state; now nearly impossible because of a severe internet blackout, isolating people and stifling communication.
  • "Even during peacetime, it's a very difficult place to reach people ... At times, only 1% of the country has connectivity." – Arzu Rezvani [06:40]
  • "I have people who I still have not heard from in the last two weeks. And your mind starts to wander." – Arzu Rezvani [07:43]

2. Diplomatic Front: Trump’s Attempt to Rally Allies

[09:26]

• Trump’s Shifting Stance

  • Sunday (Reporter’s Pool, Air Force One): "It's the place from which they get their energy and they should come and they should help us protect it." – Donald Trump [09:35]
  • Monday: Chides allies’ lack of "enthusiasm": "We've protected them from horrible outside forces ... the level of enthusiasm, it matters to me." – Donald Trump [09:57]
  • Tuesday: "We don't need anybody. We're the strongest nation in the world." – Donald Trump [10:13]
  • Analysis: Allies—especially traditional NATO partners—are refusing to join the US campaign. There was no coalition building in advance, making US efforts at unilateral security particularly difficult. [10:28]

• Global Oil and the Strait of Hormuz

  • Daniel Yergin (oil industry expert) highlights how Japan (90%), Korea (70%), and China (45%) are dependent on the Strait—thus, while oil supply shocks are material for Asia, in the US, they register as price hikes only. [11:26]

3. Tactical & Strategic Challenges: Strait of Hormuz and Asymmetric Warfare

[12:08]

• Geography Favors Iran

  • The Gulf is long (500 miles) and the Strait narrows to two 2-mile-wide channels, now jammed with over 1,000 ships. The US may have 20 warships in the region, but Iran’s asymmetric tactics (drones, small boats, missiles) mean persistent threats. [12:28-13:58]
  • "Iran just needs these small kind of guerrilla type warfare at sea." – Greg Myre [12:28]
  • Trump claims to have "destroyed" 30+ minelaying ships, but the threat from small, nimble weapons remains. [13:58]

• Kharg Island: Oil Export Hub

  • Now in the news as Iran’s main oil export point. US has hit military targets there but not the oil facilities, which, if destroyed, would cut Iran’s exports and roil global oil markets.
  • "If [the US] did that, it would take out most of Iran's oil exports. We're talking up to 2 million barrels a day ... that would further push up global oil prices." – Greg Myre [15:01]

4. Endgame? Can Trump Just Walk Away?

[15:59]

• The initial hope that Trump could "end the war at will" seems eclipsed by the new “mess” at the Strait of Hormuz: “Can President Trump walk away from this—a problem that he created—and just exit this war?” – Mary Louise Kelly [16:45]
  • Greg Myre: "He could still do it now, but he would leave a huge mess behind ... hard to claim success if world oil prices remain high and there's no real solution here." [16:45]
  • Arzu Rezvani: Many Iranians fear a US withdrawal, believing continued strikes are needed to prevent a harsher, even more hardline regime; others fear that ongoing targeting only furthers radicalization and risks a failed state.
    • "If you don't (continue the campaign) and if this ruling establishment endures, the fear is that they will crack down even harder on people ... Iran could become a failed state." – Arzu Rezvani [18:12]
    • "When you go and kill an uncle, a father, their children often don't want to come to the negotiating table. They want to seek revenge." – Arzu Rezvani [19:33]

5. Washington Update: Senate Grills Intelligence Chiefs over Iran

[21:15]

• Senate Intelligence hearings focused on whether Iran posed an "imminent threat" as pretext for war.

  • Tulsi Gabbard (DNI): "Senator, the only person who can determine what is and is not an imminent threat is the president." [22:38]
  • Greg and Mary Louise note this abdicates traditional intelligence responsibilities. [22:45-22:48]

• Joe Kent's Resignation

  • The outgoing director of the National Counterterrorism Center quit in protest, stating Iran did not pose an imminent nuclear threat:
    • "Was Iran on the verge of getting a nuclear weapon? No, they weren't." – Joe Kent (citation via interview) [24:05]
  • Background on Kent: once viewed as a Trump loyalist, with controversial views, yet now aligned with intelligence community consensus on Iran.

6. Open Source Intelligence Notebook (OSINT)

[27:59]

• Greg Myre:

  • Reports on mysterious shortwave broadcasts of random numbers (in Persian) since the start of the war—a classic “numbers station” possibly used for clandestine intelligence.
    • "Anybody could listen in, but if you have an encryption key, those numbers make sense ... It's considered a really unbreakable system." [28:20-29:24]

• Arzu Rezvani:

  • Focuses on popular anonymous Iranian social media account “Vaheed Online”; this week, state media claims to have hacked him—a message likely meant to intimidate both the account holder and would-be sources in Iran. [29:39-31:10]

• Mary Louise Kelly:

  • Shares a lighter OSINT tidbit: Canadian and Finnish leaders spotted jogging together in London’s Hyde Park, providing a rare public glimpse into informal “cardio diplomacy.” [31:10-32:50]

Notable Quotes & Memorable Moments

• "She had wished that some of the airstrikes on her city had killed her." – Arzu Rezvani, on the despair of an Iranian woman at the border [05:53]
• “We don’t need them.” – President Trump on refusing allied help [10:13]
• "Japan gets 90% of its crude oil from the Strait of Hormuz ... so for them it's really a physical shortage.” – Daniel Yergin [11:26]
• "It can’t be with all the ships all the time. And Iran just needs these small kind of guerrilla type warfare at sea." – Greg Myre [12:28]
• "You could imagine a scenario in which President Trump can point to the fact that at least 10 of Iran's top officials and the Supreme Leader have been eliminated as a success. ... If he's good at anything, it's the way he's able to brand things." – Arzu Rezvani [17:39]
• "The only person who can determine what is and is not an imminent threat is the president." – Tulsi Gabbard [22:38]
