The Cycle of Escalation: On the U.S. and the War with Iran

Yemen's Ansar Allah group, widely known as the Houthis, has declared a naval blockade on Saudi Arabia, signaling the conflict involving Iran has escalated into its most perilous stage. Despite controlling most of Yemen's major population centers, including its capital Sana'a, the Houthis, a staunch Iranian ally, had previously refrained from direct engagement due to a fragile yet functional ceasefire agreement with Saudi Arabia. This truce effectively disintegrated on July 13 following an assault on Sana'a airport by forces linked to "Yemen's internationally recognized government," which is based in Saudi Arabia and commands loyal units within Yemen, even though the Houthis remain the nation's dominant political and military power. Attributing the attack to Riyadh, the Houthis announced on July 20 their intention to block ships bound for Saudi ports along the Red Sea. Saudi Arabia, whose crude oil and other exports via the Strait of Hormuz have been significantly curtailed by Iran’s own blockade, has increasingly relied on its Red Sea terminals, particularly Yanbu. Tankers departing from Yanbu for Asian markets must navigate the Bab-el-Mandeb Strait, a vital waterway connecting the Red Sea to the Gulf of Aden and the Arabian Sea. Given their extensive control over Yemen's Red Sea coastline overlooking Bab-el-Mandeb, the Houthis possess the capability to enforce this critical maritime restriction. When Iran previously closed the Strait of Hormuz following the onset of the U.S.-Israel war on February 28, all nations bordering the Persian Gulf struggled to maintain their export operations. Saudi Arabia, however, mitigated this impact by utilizing its East-West Pipeline, which connects its eastern oilfields to its Red Sea export facilities. Should the Houthis impose a complete blockade on the kingdom, Riyadh could encounter substantially more severe economic disruption. This prospect, combined with Iran’s targeting of Kuwait’s desalination infrastructure and power grid—actions taken after U.S. assaults on Iranian civilian sites—presents a stark outlook for the conflict and its wider regional repercussions. While the initial phase of Iran’s retaliatory strategy focused on the Persian Gulf monarchies, the subsequent stage broadened its scope to include Jordan, a nation hosting two significant U.S. military installations. Now, with the Houthi blockade, the economic strain imposed by the war is poised to intensify even further. U.S. President Donald Trump had a clear opportunity to withdraw from the escalating conflict when he formalized a memorandum of understanding with Iran on June 17. However, by reigniting hostilities over disagreements concerning command of the Strait of Hormuz, Mr. Trump has not only squandered that crucial chance but has also heightened the danger of entangling the United States in yet another protracted and unwinnable war. At this juncture, he appears to be applying the same military strategies against Iran repeatedly, seemingly anticipating different outcomes. If Mr. Trump genuinely seeks a resolution, he must alter his approach, advocate for an immediate cessation of hostilities, and recommit to diplomatic solutions.
