Discussion

Sam Dewinski:

On September 8, Houthi forces launched missiles and drones toward several southern Saudi locations, including Khamis Mushait, Abha, Jazan and Najran. Saudi authorities reported 73 people wounded. Fires were reported at oil facilities and utilities, with some temporary suspensions, and fresh attacks followed the next day. Saudi-led forces responded with strikes in Yemen. The historical point is that this comes after the breakdown of a largely effective 2022 truce—not after the collapse of a settled peace treaty. The conflict was never politically resolved.

Red Velhouse:

So this is a renewed escalation inside an unresolved war. Ann, where does Pakistan’s warning fit into that picture?

Ann Tofado:

Pakistan has entered the story very deliberately. According to Saudi, Pakistani and Iranian sources cited by Reuters, Islamabad conveyed a Saudi message urging Tehran to use its influence to stop the attacks. Pakistan’s defense minister then said that aggression against one member of the new Saudi-Türkiye-Pakistan arrangement could be treated as aggression against all three, and that continued spillover into Saudi territory could make the agreement operational. That sends two signals at once: deter further attacks and reassure Riyadh without yet promising a Pakistani military intervention.

Red Velhouse:

Is Islamabad primarily warning Iran, reassuring Saudi Arabia, or trying to avoid being pulled into the war itself?

Ann Tofado:

All three objectives fit the public record. Pakistan has longstanding defense and economic ties with Saudi Arabia, and it has just joined a collective-defense framework with Saudi Arabia and Türkiye. But it also borders Iran and has a strong interest in keeping that relationship workable. So Islamabad is saying that Saudi territory cannot be attacked without consequences while avoiding a promise to send troops into Yemen or join offensive strikes. That ambiguity is intentional—and it may be the only way to balance those competing interests.

Sam Dewinski:

And that balancing act reflects a wider historical pattern. A state may use a partner or aligned movement to impose costs while denying direct responsibility. But the analogy has limits. The Houthis are aligned with Iran, yet they have their own political and military interests. They sometimes coordinate with Tehran and sometimes act independently. Treating them as a remote-control Iranian unit could produce bad policy, because pressure on Iran may not automatically stop Houthi decisions.

Red Velhouse:

That brings us to the central dispute. Iran says it does not control the Houthis. Two anonymous Iranian sources cited by Reuters alleged that Tehran encouraged the latest attacks, promised more funding and weapons, and that Islamic Revolutionary Guard Corps personnel helped coordinate them. What can we responsibly conclude?

Ann Tofado:

We should separate what is established from what remains disputed. Iran’s denial is an attributed position, and the allegations are also attributed and disputed; they are not independently resolved facts. Politically, however, the disagreement matters even before it is settled. Tehran may want influence without accepting full responsibility. The Houthis may benefit from Iranian support while retaining room to pursue a Yemen-centered agenda. That creates controlled ambiguity: useful for deterrence, but dangerous in a crisis because every side can misread who is actually deciding.

Kate Burvish:

And that uncertainty has a material cost. Jazan is not just a location in the headlines. Its refinery is designed for capacity of up to 400,000 barrels per day and is connected to industrial and power infrastructure. The reports establish fires and temporary disruption, but not a lasting loss of Saudi production. That distinction matters: markets can price risk immediately even when the physical supply impact remains limited—unless repeated attacks damage facilities or force longer suspensions.

Red Velhouse:

Kate, then what would turn market anxiety into a genuine global energy shock?

Kate Burvish:

Repetition and geography. I would watch three thresholds. First, repeated or lasting damage at facilities such as Jazan, rather than isolated fires and short suspensions. Second, attacks on tankers or a broad suspension of Red Sea transit. Third, evidence that both Bab el-Mandeb—the chokepoint connecting the Red Sea and Gulf of Aden—and the Strait of Hormuz are under sustained threat. Those risks could raise insurance costs, divert ships around the Cape of Good Hope, lengthen deliveries and increase energy prices. But that remains a scenario, not the situation established so far.

Sam Dewinski:

That economic threshold also connects to Saudi Arabia’s historical dilemma. Riyadh intervened in Yemen in 2015 after the Houthis seized Sanaa and much of northern Yemen. The intervention became a costly regional war. The 2022 truce reduced cross-border fighting without resolving the political conflict. Saudi leaders therefore face a familiar choice: retaliate enough to defend territory and credibility, but not so broadly that they recreate an open-ended campaign.

Red Velhouse:

And what appears to have triggered this round?

Ann Tofado:

Reports identify a Saudi-led strike on the Sanaa airport runway after an Iran-linked flight attempted to reach Houthi-held Sanaa. The latest Houthi attacks can therefore be read in several ways: retaliation for that strike, pressure against Saudi policy, part of the wider United States-Iran conflict, or all three at once. The danger is that each participant can describe its own action as defensive while expanding the conflict.

Red Velhouse:

Let’s turn to the new pact. The Makkah Joint Defence Agreement, signed on August 7, says an armed attack on one member is to be regarded as an attack on all three. Does a Houthi attack from Yemen automatically activate it?

Ann Tofado:

The public record does not answer that automatically. The agreement contains collective-attack language and broader defense cooperation, but its precise legal effect is unclear—especially when the attacker is a non-state group operating from another country. Reported understandings say any Pakistani or Turkish role would be limited to defending Saudi territory, with no deployment into Yemen. So activation could mean intelligence, air defense, logistics or political coordination—not necessarily offensive operations.

Sam Dewinski:

That is why the pact should not yet be treated as a simple alliance analogy. Collective-defense language does not necessarily create an automatic war obligation, particularly when the members have different relationships with Iran and different appetites for intervention. The agreement is being tested almost immediately, but its implementation procedures are not publicly visible in enough detail to show how it would work.

Red Velhouse:

Ann, does that uncertainty make the pact more useful as deterrence—or less credible?

Ann Tofado:

Both possibilities are present. Ambiguity can deter an attacker by leaving the response uncertain, while giving the members room to choose a limited response. But if attacks continue, Riyadh may demand a clearer commitment. Pakistan would then have to show that its warning was credible without appearing to join a broader war, and Türkiye would face the same question about what territorial defense means in practice. No public evidence cited here shows that either country has joined Saudi retaliatory strikes.

Kate Burvish:

From the economic side, the credibility question is also about duration. Saudi Arabia has pipelines, storage and alternative ports, so it has buffers. But buffers reduce vulnerability; they do not eliminate it. The same is true of shipping. A short-lived threat may produce higher insurance costs and caution, while repeated attacks could force carriers to reroute and make the disruption much more expensive.

Red Velhouse:

Sam, what would distinguish a sharp but temporary exchange from a return to the full Yemen war?

Sam Dewinski:

Duration and geographic spread. If strikes remain concentrated in southern Saudi Arabia and western Yemen, leaders may still seek containment. If fighting reaches Saudi ports, international shipping or additional regional actors, the logic changes. We should also ask whether the cross-border restraint seen after the 2022 truce can be reconstructed. The humanitarian baseline is already severe: between August 23 and September 5, figures cited by the Associated Press from the World Health Organization and United Nations recorded at least 194 dead, more than 880 wounded and over 21,000 displaced.

Kate Burvish:

And the economic asymmetry makes every military choice harder. Saudi Arabia can draw on infrastructure alternatives, while Houthi-held areas depend on fragile supply networks and face severe humanitarian vulnerability. Escalation can impose costs on Saudi energy systems, but it can also deepen civilian hardship in Yemen and disrupt supplies ordinary people need. The suffering is distributed very unevenly.

Red Velhouse:

If the parties want to prevent that wider spread, what off-ramps are still available?

Ann Tofado:

The obvious possibilities are a renewed truce, reopening arrangements for Sanaa airport, easing blockade-related restrictions and pursuing a broader Yemen settlement. But each would require sequencing and verification. Saudi Arabia wants security guarantees; the Houthis want relief and political recognition; Iran may want leverage without direct confrontation. Pakistan could be useful as a channel because it has ties to both Riyadh and Tehran, although its new defense alignment may limit how neutral Islamabad is perceived.

Red Velhouse:

So Pakistan’s relationships could make it a useful intermediary, while its security commitment could make that mediation harder. Kate, what should viewers watch for in the coming days?

Kate Burvish:

Watch behavior rather than statements: whether major carriers continue using the Red Sea, whether insurance costs jump, whether Saudi facilities return fully to normal, and whether production data show lasting losses. Bab el-Mandeb carries important energy and commercial traffic, so the headline risk is substantial. But the measured effects so far show disruption and danger—not yet a sustained global supply crisis.

Sam Dewinski:

And watch whether the parties preserve an off-ramp. Yemen’s history shows how limited retaliation can become a regional war when local grievances, outside alliances and strategic waterways overlap. But history is not destiny. The 2022 truce demonstrates that even an unresolved conflict can be restrained if the governments involved decide that restraint serves them better than escalation.

Red Velhouse:

The central unresolved issue is how much influence Iran actually exercises over Houthi decisions—and whether the new Makkah defense pact is an automatic commitment or a political deterrent with room for discretion. Watch for sustained damage to Saudi energy infrastructure, attacks on shipping, wider geographic spread, and any formal move by Pakistan or Türkiye beyond diplomatic support and territorial defense. Also watch for efforts to restore the 2022 truce, because the difference between a contained exchange and a renewed regional war may be measured in diplomacy as much as in missiles.
