Crosetto’s move was a response to the risk that a rapidly expanding Houthi presence on Yemen’s Red Sea coast could make the Bab al-Mandeb unsafe or effectively unusable for Italian shipping. He and Italy’s chief of defence staff ordered the Navy to prepare an escort mission rather than wait for a collective EU decision, judging that the economic and supply-chain consequences of delay were too great. 1

• Why the strait matters: Bab al-Mandeb is only about 29 km wide at its narrowest point, with Perim/Mayyun Island dividing the traffic channels. It links the Gulf of Aden and Indian Ocean to the Red Sea—and, through the Suez Canal, to Europe—making it the southern gateway to the Suez route. 3

• Energy and trade exposure: It carries Persian Gulf oil and gas bound for Europe and North America. U.S. energy data put the connected Red Sea/Suez route at roughly 11–12% of seaborne oil trade, while earlier estimates put Bab al-Mandeb at about 8% of global LNG trade; interference forces ships around the Cape of Good Hope, adding time, fuel, freight cost, and pressure on energy prices. 24

• The “two-chokepoint” problem: Reports that disruption at Hormuz had redirected Saudi export flows toward Red Sea outlets meant Bab al-Mandeb was no longer merely an alternative risk—it became a second potential bottleneck for Gulf energy. Houthi control near the Red Sea entrance therefore increases leverage over both commercial shipping and Saudi export options. 5

• What changed on the ground: Houthi forces reportedly took Mokha, advanced along the western coast, and reached Perim Island, alongside gains on the Hanish islands. Those positions provide proximity to, and potential observation or attack access over, the narrow navigation lanes. 67

• Saudi conflict and humanitarian fallout: Saudi Arabia and the Houthis then exchanged cross-border strikes, while Yemenis fled fighting by boat across the Red Sea. The escalation broadened the danger from ship attacks to a regional confrontation capable of disrupting oil supply and worsening displacement. 8

• Why responses are fragmenting: Saudi Arabia faces the choice of absorbing security and export costs or seeking accommodation with Tehran; Washington initially signalled intelligence support rather than direct intervention, while U.S. officials also held contacts with Houthi representatives in Oman. Italy, by contrast, is preparing a national naval response outside the EU’s slower consensus process. 5910

The prospect of additional U.S. military action against Iran—or of retaliation through Iranian-aligned groups—raises the risk that commercial shipping becomes both a target and a bargaining instrument. Italy’s decision is thus defensive and economic: preserve passage for its ships before a local Houthi advance and the wider Iran conflict turn Bab al-Mandeb into a closed or prohibitively dangerous route. 16
