The Syrian regime, long propped up by the strategic partnership of Iran and Russia, is teetering on the brink of losing Aleppo, a city that symbolizes its survival in the brutal civil war. This potential loss to Hayat Tahrir al-Sham (HTS), an opposition group with roots in Al Qaeda, could mark one of the most significant setbacks for Bashar al-Assad in years.
Aleppo, a crucial economic and cultural hub, represents far more than geography in this conflict. It was a centerpiece of the regime’s resurgence in 2016, when a coalition of Iranian militias, Hezbollah, and Russian forces orchestrated its recapture from rebel factions. At that time, Iran’s influence was at its peak, with Qasem Soleimani, the late commander of the Iranian Quds Force, rallying forces to save the regime. The city’s fall back into opposition hands would symbolize the unraveling of this once-powerful alliance.
The regime’s vulnerability today underscores the erosion of support from its allies. Russia, preoccupied with its ongoing war in Ukraine, has diverted resources and focus, while Iran’s regional influence has been systematically diminished by targeted Israeli operations. Hezbollah, once the linchpin of Iran’s proxy network in Syria, has been significantly weakened by Israel’s precision strikes on its fighters and supply lines. The loss of key leaders, such as Soleimani and Hezbollah’s former chief Hassan Nasrallah, has further hollowed out the cohesion and strength of these forces.
The resurgence of HTS, a group that once sought to rebrand itself to court Western tolerance but remains a hardline faction, demonstrates the regime’s inability to defend its positions effectively. HTS’s swift advance through dozens of villages in the Aleppo countryside serves as a stark reminder of Assad’s declining military capacity. The rapid retreat of Syrian forces resembles the collapse of the Iraqi army in Mosul in 2014, when the city fell to ISIS.
This shift comes at a time when the Syrian regime had begun to believe that regional normalization was within reach. Diplomatic overtures from Gulf states, the normalization of ties with Egypt, and inclusion in initiatives like BRICS had given Assad the illusion of newfound legitimacy. Yet, the reality on the ground paints a far grimmer picture.
Iran’s strategic setbacks have compounded the regime’s crisis. Syria has been the linchpin of Iran’s regional strategy, a vital corridor for transferring weapons and support to Hezbollah in Lebanon. However, Israel’s relentless campaign to prevent Hezbollah’s rearmament has disrupted these operations, leaving the Syrian regime increasingly isolated. The loss of Aleppo would further weaken Iran’s regional position, cutting off a crucial foothold and exposing its diminishing ability to project power through proxies.
The ripple effects of the Aleppo crisis could be far-reaching. Assad’s forces may be compelled to redeploy troops from other critical regions to attempt a counteroffensive, leaving areas like Homs, Hama, and even Damascus vulnerable. Such moves could open the door for a resurgence of ISIS in eastern Syria or embolden Turkish-backed opposition groups in the north.
Meanwhile, Iranian-backed militias, such as Kataib Hezbollah and Asaib Ahl al-Haq, may step into the fray to bolster the regime’s faltering defenses. However, their presence risks escalating tensions with U.S. forces stationed in eastern Syria and the Syrian Democratic Forces (SDF), further destabilizing an already volatile region.
The Aleppo crisis also highlights the unintended consequences of Iran’s broader regional strategy. While Tehran mobilized its proxies for a multi-front confrontation with Israel in the aftermath of the Hamas attack on October 7, the strategy has backfired. Iran now faces overstretched resources and diminished operational capabilities, compounded by the loss of thousands of Hezbollah fighters and the degradation of its command structure.
This evolving situation exposes the fragility of the Assad regime’s reliance on foreign backers. The normalization efforts that seemed promising just weeks ago now appear hollow, as Aleppo’s fall would shatter any illusions of stability or recovery. For Iran, the implications are profound. Losing influence in Syria, the crown jewel of its regional ambitions, could mark a turning point in its ability to shape the balance of power in the Middle East.
The battle for Aleppo serves as a stark reminder of the fluid and unpredictable nature of the Syrian conflict. As Iran struggles to maintain its foothold, and as Assad’s regime shows increasing signs of weakness, the region stands at a pivotal juncture. The outcome of this crisis will not only shape Syria’s future but could also redefine the broader geopolitical dynamics of the Middle East.
