Iran Grapples with a New Strategic Reality after Assad’s Ouster

The December 2024 ousting of Bashar al-Assad marked a pivotal moment in Middle Eastern geopolitics, dramatically shifting the regional balance of power. For Iran, the downfall of one of its most steadfast allies represents a significant blow to its influence in Syria and across the broader Levant. While this moment will have immediate and far-reaching consequences, Iran’s loss of Syria also underscores the weakening of Tehran’s soft and hard power in the region. Since the bloody Syrian Civil War began, Iran has used Syria to boost its so-called Axis of Resistance, capitalizing on the power vacuum in the region to flood money, men, and material to its proxies. Indeed, the Iranian-Syrian alliance was not merely geopolitical but also ideological, grounded in shared resistance against Western and Israeli influence in the region.

However, repercussions from the Israel-Gaza war have dealt a heavy blow to Lebanese Hezbollah and by extension the Assad regime, effectively dismantling this axis. Iran’s access to the Mediterranean has been severely restricted, and its ability to threaten Israel via Hezbollah is now in jeopardy. With Syria in disarray, Tehran’s ambitions to dominate the volatile region look increasingly fragile.

Nonetheless, Iranian officials, including Supreme Leader Ayatollah Ali Khamenei, have publicly downplayed the implications of Assad’s ouster, emphasizing the resilience of the Islamic Republic’s “resistance axis.” However, these statements belie the profound challenges Iran faces in adapting to the new reality. The loss of a loyal regime in Damascus may push Tehran to rethink its long-term “forward defense” strategy, which envisions a buffer of proxy forces across the region capable of engaging Israel far from Iranian territory.

Though the forward defense strategy yielded significant results for Tehran over the last two decades, the geopolitical landscape has dramatically changed with the decimation of Hamas and Hezbollah by Israel and the fall of Assad. Iranian policymakers must come to terms with the collapse of their foreign policy doctrine and the ascendancy of regional adversaries, including Israel and Turkey.

A New Power Player

The role Turkey played in Assad’s downfall highlights Ankara’s competing influence in the region. As Moscow reduced its military footprint in Syria, Ankara adeptly exploited the power vacuum left behind by backing Hayat Tahrir al-Sham (HTS) and other anti-government forces. Turkey’s soft power strategy—rooted in economic investments and cultural outreach—also played a crucial role in eroding Assad’s control. Perhaps most importantly, Ankara’s efforts to position itself as a stabilizing force in northern Syria have curtailed Iran’s influence. By aligning with Sunni-majority opposition factions, Turkey directly challenged Tehran’s strategy of backing Alawites and other religious minorities.

Turkey’s main motivation behind this timely alleged operation in Syria may be attributed to the second Trump administration, which is likely to continue its fiercely anti-Iranian policies. Thus, Ankara may have sought to send positive signals to Donald Trump’s team, highlighting its crucial role in deterring Iranian influence in the Middle East.

Irrespective of Ankara’s motivations for backing the Syrian opposition, Assad’s fall has created a dangerous security vacuum in Syria and the broader Middle East that poses both risks and opportunities for regional and international actors. The potential ramifications are legion, such as the resurgence of extremist groups like the Islamic State, the worsening of the humanitarian crisis, emergent proxy conflicts as pro-Iranian militias attempt to reassert themselves, and shifts in energy geopolitics, particularly for pipelines and transit routes. As rival powers compete for control over strategic corridors and jostle for influence with the government in Damascus, the potential for controversy and conflict looms large.

Facing a New Reality

The ousting of Bashar al-Assad represents more than just a change in regime; it signals a profound realignment of Middle Eastern geopolitics. For Iran, the loss of Syria undermines its long-standing strategy to dominate the Levant and projects an image of vulnerability that its adversaries may be quick to exploit. Russia’s diminished role and Turkey’s growing assertiveness in Syria further complicate Tehran’s path to recovery.

Tehran remains concerned that Israel’s defeat of Hamas and Hezbollah may soon expose its last effective proxy group: the Houthis. The Houthis’ disruptive activities have seen the group fire missiles and drones at ships transiting the Red Sea and at Israel itself. In response,  Israeli forces have conducted precise attacks on Sana’a. Having seized the strategic initiative, Israel may continue to launch airstrikes until destroying all of their military infrastructure and stockpiles, as Iran currently lacks credible mechanisms to deter Israel elsewhere.

In the short term, the radical transformation of the regional order wrought by Assad’s downfall poses significant challenges for stakeholders within the Middle East and beyond. However, the new reality also offers an opportunity for diplomatic initiatives to address the root causes of conflict and build a more secure future for the region and its people. For Iran, adapting to this new reality will require recalibrating its foreign policy and exploring alternative, perhaps less adventuristic, avenues to maintain its influence in an increasingly challenging security environment.
