Yemen - 2026
Yemen is partitioned by a civil war that has run since 2014 - the Houthi (Ansar Allah) movement controls the capital Sana'a and most of the populous northern highlands, the internationally-recognized Presidential Leadership Council government holds Aden and parts of the south, the Southern Transitional Council operates as a Saudi-and-Emirati-aligned semi-autonomous force in the south, and the Saudi-led coalition has intervened militarily since 2015 in support of the recognized government. Population about 33M, GDP collapsed to perhaps $20B PPP. The strategic identity is the chokepoint civil war - Yemen's geographic position on the Bab al-Mandeb strait, the maritime gateway to the Red Sea and the Suez Canal route to Europe, has converted the country's internal conflict into a strategic problem for global shipping and the maritime powers that depend on it.
Starting position
The military situation in Yemen splits across multiple actors. The Houthi movement fields perhaps 200,000 personnel - including substantial Iranian-supplied or Iranian-pattern medium-range ballistic missiles, anti-ship cruise missiles, suicide drones, and the maritime systems used in the Red Sea shipping campaign that began in November 2023. The recognized government's forces are a fraction of that, organized largely by Saudi training and finance. The Southern Transitional Council operates with Emirati support and effective control over much of southern Yemen including the Aden port and Socotra. The Saudi coalition has effectively wound down direct ground operations after the 2022 truce that has held in modified form, though Saudi airpower remains positioned. The Houthi anti-shipping campaign in 2023-25 produced the largest US Navy combat operation since World War II in defense of merchant traffic - Operation Prosperity Guardian and the subsequent strike packages.
What turns the campaign
What each Yemeni actor wants is different. The Houthi movement wants international recognition or at least de facto acceptance of control over the populous north, sanctions relief, and continued strategic relevance through the Bab al-Mandeb leverage and the alignment with Iran and the broader Resistance Axis. The recognized government wants the territorial reunification it has been formally pursuing for a decade, sustained Saudi support, and a political settlement that institutionalizes its constitutional status. The STC wants formal southern independence or autonomy at minimum, the Aden-port economic asset preserved, and continued Emirati backing. What all of them fear is a regional escalation - Saudi-Iran confrontation, Israeli strikes, US strike packages - that converts Yemen back into a hot active theater after the 2022-onwards reduction in operational tempo, and an internal-Houthi crisis that destabilizes the only actor with credible territorial control over the populous north.
Signature challenge
The Bab al-Mandeb leverage
Yemen's central strategic problem is that the chokepoint geography that gives any actor controlling it international relevance is also the geography that guarantees external intervention against any actor willing to use it disruptively. The Houthi shipping campaign of 2023-25 was the demonstration: real damage to global shipping (Suez transits dropped sharply, traffic rerouted around the Cape of Good Hope), real cost imposition on the Western maritime powers, and real US-and-British strike packages in response that did not, in the end, stop the campaign or topple the regime imposing it. NationFall surfaces this as the Yemeni campaign's defining tension: the leverage works only as long as someone is willing to bear the cost of exercising it, and the cost is being shifted in real time among Houthi, Iranian, Saudi, Emirati, and Western actors none of whom have a stable answer.
