Yemen’s return to war: The collapse of the post-2022 truce and the new strategic contest in the Red Sea

Yemen’s conflict has entered a renewed phase of escalation following several years of relative calm after the 2022 truce. Although political divisions remained unresolved, large-scale fighting between the Houthis and forces aligned with Yemen’s internationally recognized government and Saudi Arabia substantially declined. Since July 2026, however, Houthi attacks against Saudi territory, strategic infrastructure and maritime traffic have intensified alongside fighting across Yemen’s front lines. Concurrently, the wider US–Iran confrontation has increased Yemen’s significance within regional security dynamics. This article examines the escalation’s implications for Yemen, Saudi Arabia and Red Sea security. It argues that the crisis differs from the pre-2022 conflict because the Houthis have developed greater long-range missile, drone and maritime capabilities, enabling them to exert disproportionate strategic leverage through the Bab el-Mandeb. Saudi Arabia must balance territorial and economic security against the costs of renewed warfare. The article assesses three trajectories: large-scale civil war, prolonged controlled escalation and negotiated de-escalation, arguing that the erosion of post-2022 restraints presents the principal regional danger.
