Bashar al-Assad’s regime has fallen in Syria. How will this impact an already fractured region?

The swift and unexpected fall of the Syrian capital^[1], Damascus, to Sunni opposition forces marks a pivotal moment in the modern history of the Middle East.

Bashar al-Assad’s regime had withstood more than a decade of uprisings, civil war and international sanctions since the onset of widespread protests in 2011. Yet, it collapsed in a remarkably short period of time.

This sudden turn of events, with the opposition advancing without significant battles or resistance, has left regional powers scrambling to assess the fallout and its broader implications.

This dramatic development signals a reshuffling of power dynamics in the region. It also raises questions about Syria’s future and the role of its neighbours and global stakeholders in managing the post-Assad landscape.

What does the future hold for Syria?

With the collapse of the Assad regime, Syria now finds itself fragmented and divided among three dominant factions, each with external backers and distinct goals:

1. Syrian opposition forces, led by Hayat Tahrir al-Sham^[2]: These groups, supported by Turkey, now control central Syria, extending from the northern border with Turkey to the southern border with Jordan.

Although they share a common religious identity, the Sunni factions have a history of internal conflicts, which could hinder their ability to form a cohesive government or maintain long-term stability.

The opposition forces range from former jihadists coming from Islamic State and al-Qaeda to secular groups such as the Syrian National Army^[3], which split from Assad’s army after the 2011 uprising.

2. Kurdish forces: The Kurdish groups control territory in northeastern Syria, bordering Turkey in the north and Iraq in the east. They continue to receive support^[4] from the United States, which has established military bases in the area. This support risks escalating tensions with Turkey, which views Kurdish empowerment as a threat to its territorial integrity.

3. Alawite forces: Pro-Assad Alawite factions^[5], primarily situated in the coastal regions of western Syria, maintain strong ties with Iran, Iraq and Lebanon’s Hezbollah militant group. These areas could serve as a stronghold for remnants of Assad-aligned groups after the opposition’s takeover, perpetuating sectarian divides.

The stark divisions among these groups, combined with the absence of a mutually acceptable mediator, suggest that Syria may now face prolonged instability and conflict.

How will this impact the region?

The swift fall of the Assad regime has profound implications for the major players in the Middle East.

The Sunni rebel forces, with strong Turkish backing, capitalised on a moment of vulnerability in Syria. The Assad regime’s allies were preoccupied — Russia with its ongoing war in Ukraine, and Iran and its proxies with their ongoing conflict with Israel. This provided a strategic opportunity for the rebels to advance swiftly across Syria to the capital, Damascus.

Turkey already effectively controls a strip of territory in northern Syria, where its military has been fighting Syrian Kurdish forces. Now, with the victory of its Syrian opposition allies, Turkey is expected^[6] to expand its political and military influence in Syria, causing more challenges for the Kurdish minority fighting for its autonomy^[7].

Israel is also in a strategically better position. The fall of Assad disrupts the so-called “axis of resistance^[8]”, comprised of Iran, Syria and Tehran’s proxy groups like Hezbollah in Lebanon, Hamas in Gaza and the Houthi rebels in Yemen.

Iran’s critical military supply lines to Hezbollah will likely be severed, isolating the militant group and likely weakening it even further.

Additionally, the fragmentation of Syria into ethnic and religious factions could diminish the regional focus on Israel, providing space for it to pursue its broader strategic goals. After Israel agreed to a ceasefire with Hezbollah last month, for example, Israeli Prime Minister Benjamin Netanyahu emphasised^[9] a shift in focus to countering the “Iranian threat”.

Iran, meanwhile, has the most to lose. Assad was a crucial ally in Iran’s regional proxy network. And the collapse of his government follows the significant damage that Israel has already inflicted on its other partners, Hamas and Hezbollah. Iran’s regional influence has now been severely diminished, leaving it more vulnerable to direct conflict with Israel.

The fragmentation of Syria also poses significant security risks to its neighbouring countries – Turkey, Iraq, Jordan and Lebanon. Refugee flows, cross-border violence and sectarian tensions are likely to escalate. Turkey is already hosting^[10] more than 3 million Syrian refugees – many of whom it hopes will return home now that Assad’s government is gone.

For Iraq and Lebanon, this instability could exacerbate their fragile political and economic situations. The Balkanisation of Syria along ethnic and religious lines could encourage other groups in the region to rebel against governments in the pursuit of their own autonomy. This risks entrenching divisions and prolonging conflict across the region.

While many Syrians have celebrated Assad’s fall, it remains to be seen whether their lives will improve much. With the absence of a unified and internationally recognised government in Syria, sanctions are unlikely to be lifted. This will further strain an already devastated Syrian economy, deepening the humanitarian crisis and potentially fuelling extremism.
