Yemen: When Bab el-Mandeb Becomes a Substitute for the State — Why Military Gains May Not Produce Peace

Key Assessment
Yemen's conflict increasingly combines a struggle for territorial authority with competition over Red Sea security. This assessment tests a central hypothesis: strategic geography gives armed actors the capacity to impose regional and international costs that exceed their ability to produce stable governance at home. Threats to shipping corridors and airports can enhance negotiating leverage without establishing political legitimacy or rebuilding public institutions. The risk is that regional security arrangements manage Yemen's external threats while leaving its domestic fragmentation largely intact.
1. What Has Changed?
The 2022 truce reduced large-scale fighting without reconciling competing political and economic authorities. Renewed escalation in 2026 changed the picture. On 10 September the UN Special Envoy reported that the Houthis had advanced along the western coast and gained control of Mokha at that time, with the situation remaining fluid. In early October Saudi-backed government forces announced gains near Bab el-Mandeb, while contested claims about control continued. Strikes on Aden airport and Saudi airports on 7 October underscored the regional scope of the confrontation. Territorial reports should be read as dated observations, not fixed maps.
2. The Houthi Dilemma: Disruption Versus Governance
Ansar Allah controls Sana'a and extensive territory in northwestern Yemen and maintains missile and drone capabilities extending beyond its front lines. Yet capacity to disrupt trade or threaten infrastructure is different from capacity to pay salaries, provide services, and manage productive economic activity. The more valuable long-range capabilities become as bargaining assets, the more difficult limits on them may be to accept. This tension does not establish that negotiations are impossible; it helps explain why limited economic concessions alone cannot settle the place of armed power in a future Yemeni order.
3. The Government's Dilemma: Sovereignty Without Consensus
International recognition gives Yemen's government diplomatic legitimacy but does not automatically integrate competing institutions and local interests. Changes among southern forces in late 2025 and 2026 illustrated that military alignment against the Houthis is not the same as agreement on territorial representation, resource sharing, or the structure of the state. Recapturing coastal territory could strengthen the government's position, yet sustainable sovereignty requires rules accepted across diverse regions. Deferring these questions in the name of wartime mobilization risks reproducing conflict after the main battles subside.

4. Bab el-Mandeb: Geography Without Political Legitimacy
Bab el-Mandeb connects the Red Sea to the Gulf of Aden and links domestic military control to regional commerce, energy security, and international shipping. An armed group able to threaten navigation may gain influence far beyond its territorial base. Conversely, external powers may prioritize maritime protection without investing equally in Yemen's political reconstruction. Crucially, the possibility of disruption must be distinguished from observed disruption: a September UN briefing reported that commercial shipping was still moving despite rising concern. Maritime leverage therefore cannot be equated with either sovereign authority or good governance.
5. The Destructive Conflict Loop
KMT's framework links internal fragility with external destabilization in a self-reinforcing mechanism. Weak institutions allow armed fragmentation; conflict distributes control over revenue, ports, and transport routes; economic interests adapt to military authority; displacement and declining services weaken civilian institutions; reunifying resources and forces becomes more costly; and the resulting structures enable continued conflict. Yemen adds a distinctive element: strategic maritime geography can reward actors with external leverage for their capacity to threaten rather than govern. This does not imply universal benefit from war: civilians incur immense losses, even as specific organizational interests may become tied to continued division.
6. The Political Economy of Division
Yemen's administrative division has damaged unified public revenue collection and services while oil exports remain disrupted. The World Bank estimated a 1.5 percent decline in real GDP in 2025 and projected further contraction for 2026 in its May report. Any ceasefire that leaves unanswered who collects revenues, finances public wages, manages ports, or coordinates currency policy risks freezing the political economy of fragmentation. Shared fiscal rules and predictable public spending are thus integral to a peace agreement rather than technical issues postponed until after one.

7. Human Security and the Capacity for Peace
The UN's 2026 humanitarian plan estimated more than 22 million people needing assistance and protection, approximately 18.3 million facing acute food insecurity, and around 5.2 million internally displaced. These estimates predate the latest escalation and must not be treated as its specific casualty totals. Their significance is structural: prolonged loss of livelihoods, education, healthcare and water erodes the social foundations required for reconstruction. Reducing cross-border strikes without enabling families and institutions to recover would leave the destructive loop substantially intact.
8. Regional Security and Reciprocal Threats
Saudi Arabia regards threats to its border, airports and critical infrastructure as direct security concerns, while the Houthis may perceive retention of long-range capabilities as insurance against an unfavorable settlement. Measures each side considers protective can heighten the other's threat perception. External alliances also affect each side's capacity and incentives to continue fighting. Nevertheless, an enforceable system of reciprocal commitments on attacks, maritime security and economic access could begin to alter these calculations if it supports rather than displaces domestic state-building.
9. The Mediation Dilemma
Mediators face three linked questions: how should cross-border armed capabilities be constrained; how can legitimate institutions accommodate southern and local demands; and how can public revenues be reunified without excluding communities? A deal distributing posts solely among armed leaders could reproduce the original fragmentation. A regional deal focusing only on navigation could reduce external risk while leaving domestic political disputes unresolved. A constructive cycle requires shared rules for armed authority, accountability, resource distribution and regional security.
10. What Would Challenge the Hypothesis?
The assessment would weaken if verifiable developments showed strategic assets being brought under common civilian institutions: sustained restraint on drone and missile strikes; enforceable agreements on wages and revenues; ports and roads managed as public infrastructure rather than instruments of military leverage; inclusive participation of southern and local actors; and visible improvement in services and livelihoods. Changes in front lines alone, without changes in these rules, would not establish that Yemen's institutions are being reunited.
11. Strategic Scenarios
Four conditional pathways merit attention: renewed fighting over the western coast; regional security containment without institutional settlement; expanded escalation exposing civilians and critical infrastructure to greater risk; or gradual de-escalation linked to fiscal arrangements, inclusive negotiations and state reconstruction. These are not certainty claims or calculated probabilities. Their direction depends on battlefield developments, external support and the willingness of Yemeni actors to alter rules governing power and resources.
Final Strategic Judgment
The decisive question is not simply who controls Sana'a, Aden, or Bab el-Mandeb. It is whether Yemen's geography can be transformed from leverage for competing armed organizations into a resource supporting public security and state reconstruction. Control of a strategic strait may produce bargaining power, but cannot substitute for legitimate institutions, shared economic rules or human security. Peace requires changing the mechanisms that reproduce conflict, not merely redrawing military front lines.
