In a significant geopolitical shift, Iran is recalibrating its regional influence as its traditional strongholds in the Levant falter. While Israeli strikes have degraded Hezbollah’s capabilities and the fall of Bashar al-Assad in Syria has severed a critical supply corridor, Tehran is expanding its strategic footprint along key maritime chokepoints, particularly the Red Sea and the Strait of Hormuz.
On September 10, Israel destroyed Hezbollah’s underground command center and weapons stores beneath the Ali al-Tahir ridge in southern Lebanon, dealing a severe blow to Iran’s most important ally. This loss compounds two years of attrition that have stripped Hezbollah of senior commanders and much of its arsenal. Similarly, Assad’s removal in 2024 eliminated one of Tehran’s few reliable state partners and disrupted the land bridge used to resupply Hezbollah.
However, the wider conflict has opened new avenues for Iranian leverage. On June 8, Esmail Ghaani, commander of the IRGC’s Quds Force, announced a “new security belt” stretching from the Persian Gulf to the Red Sea. This signals a strategic pivot toward controlling the waterways indispensable for global trade and energy exports.
In Yemen, the Houthis have seized territory along the Red Sea coast, including the port city of Mokha and Perim Island within the Bab al-Mandab strait. These gains provide a stronger foothold at the southern entrance to the Red Sea, allowing for closer monitoring of vessels and potential deployment of weapons near shipping lanes. Although the Houthis operate with significant autonomy—driven by domestic goals to consolidate power in Yemen and force Saudi Arabia to lift its blockade—their ties with Tehran have deepened since October 2023. Reports indicate Iran has supplied IRGC commanders, military advisers, and missile and drone equipment to enhance Houthi capabilities.
The interplay between these fronts creates substantial vulnerability for Saudi Arabia. While Gulf exporters have utilized “shuttle runs” through the Strait of Hormuz to maintain oil shipments, intermittent Iranian attacks sustain uncertainty and raise insurance costs. Furthermore, diverting exports to Red Sea ports is no longer a guaranteed safe haven given Houthi advances. The threat extends inland as well; a recent drone attack from Iraq damaged three pumping stations on Saudi Arabia’s East-West Pipeline, demonstrating that alternative land routes are also exposed.
Although there is no unified chain of command across Iranian, Yemeni, and Iraqi operations, attacks from Iraqi territory are viewed as part of a broader campaign coordinated by the IRGC, which has mobilized smaller cells of Shiite fighters under its direct command. This multi-front pressure aims to raise the economic costs of war for Washington and its partners, reinforcing the Iranian leadership’s belief that holding firm will improve their bargaining position.
Yet, analysts warn that Iran may be miscalculating. Prolonged confrontation risks further entrenching military coordination among non-state partners and escalating attacks, while Iran’s own economy continues to suffer under blockade conditions. Moreover, disrupting neighbors’ exports has not financed Iran’s recovery and may backfire. Saudi Arabia is increasingly resistant to any deal that formalizes dependence on Iranian restraint, as evidenced by Riyadh’s refusal to attend recent mediation talks in Oman. Gulf governments remain unwilling to legitimize Iranian claims to control maritime transit, suggesting that Iran’s expanded reach, while dangerous, does not guarantee diplomatic success.
Lost Hezbollah but gained strategic depth? It feels less like an opportunistic shift and more like desperation disguised as innovation.
The pivot to the Red Sea is a bold move, but can Iran really sustain this without collapsing its own economy first?
