Syria has undergone one of the most dramatic political collapses of the twenty-first century. On 8 December, rebel forces entered Damascus and Bashar al-Assad fled to Russia, ending more than fifty years of rule by the Assad family and nearly fourteen years of civil war. The speed was extraordinary. A rebel offensive led principally by Hayat Tahrir al-Sham (HTS) began in northwestern Syria in late November, captured Aleppo, moved through Hama and Homs and reached Damascus while much of the Syrian military simply disintegrated. A regime that survived enormous protests, years of civil war, sanctions, Islamic State, international intervention and repeated predictions of collapse disappeared in less than two weeks. The immediate reaction among many Syrians has understandably been celebration, particularly among communities subjected to imprisonment, bombardment and displacement under Assad. Yet removing a regime and constructing a state are entirely different achievements. Assad has lost Syria. That does not mean anybody else yet controls enough of Syria to rebuild it.
The speed of the collapse tells us something important about authoritarian durability. Assad’s government survived after 2011 not simply because it possessed overwhelming domestic legitimacy or institutional strength. It survived because Russia, Iran and Hezbollah supplied resources the regime itself lacked. Russian aircraft intervened decisively from 2015. Iran provided financing, advisers and military support. Hezbollah deployed experienced fighters. Those external actors helped compensate for weaknesses inside the Syrian state.
In 2024, all three became substantially less capable of doing so.
Russia is consumed by the war in Ukraine.
Hezbollah has been severely weakened by Israel.
Iran’s regional network has suffered enormous losses.
Israel has repeatedly targeted Iranian-linked infrastructure in Syria.
The external scaffolding holding Assad’s government upright therefore weakened at exactly the moment rebels tested it.
This is a useful reminder that regime stability can be externally subsidised. A government may appear durable because allies continually absorb the cost of its weaknesses. Remove the subsidy and the underlying institutional fragility becomes visible very quickly.
The Syrian military’s collapse demonstrates the same point internally. Assad’s forces possessed tanks, aircraft, uniforms and formal command structures. Yet military capability is not simply the sum of equipment. Soldiers need salaries, logistics, leadership and some reason to fight.
When those disappear, an army can become much weaker than its inventory suggests.
This is latent versus effective capacity.
A state can possess thousands of soldiers on paper while possessing far fewer soldiers willing and able to defend it under pressure.
Authoritarian regimes are particularly vulnerable to this because military institutions can become organised around political loyalty rather than competence. Leaders fear coups and therefore create overlapping security agencies, promote loyal commanders and prevent military organisations from developing too much independent authority.
These structures protect the ruler from the army.
They can make the army worse at protecting the ruler from an external opponent.
This is the coup-proofing paradox.
The same institutions that increase regime security during normal periods can reduce battlefield effectiveness during crisis.
Assad’s fall therefore should not be interpreted simply as evidence of overwhelming rebel military strength. HTS and its allies fought effectively, but the offensive succeeded partly because the state they attacked was much weaker than its apparent longevity suggested.
This distinction matters for evaluating what happens next.
HTS is not a conventional democratic opposition movement. The organisation emerged from the jihadist forces that fought during the civil war and has historical roots in al-Qaeda’s Syrian affiliate, although its leader Ahmed al-Sharaa, previously known as Abu Mohammed al-Golani, broke publicly with al-Qaeda years ago and has spent considerable effort attempting to reposition HTS as a Syrian Islamist rather than transnational jihadist movement.
That transformation now faces its real test.
Running an insurgency rewards discipline, ideological commitment and military effectiveness.
Running a country requires something much broader.
Taxation.
Electricity.
Schools.
Police.
Courts.
Trade.
Minority protection.
Foreign relations.
A functioning currency.
An armed group can seize a ministry building.
That does not give it the administrative knowledge contained inside the ministry.
This is the rebel-to-state transition problem.
Successful insurgencies frequently discover that the institutions they spent years fighting are also the institutions required to keep water running once they win.
Destroy too much of the old state and administrative capacity collapses.
Preserve too much and networks responsible for repression remain embedded.
Syria therefore needs to distinguish the Assad regime from the Syrian state.
They are not the same thing.
The security organisations responsible for torture and political repression require fundamental reform and accountability.
Ordinary civil servants, engineers, teachers, doctors and municipal administrators are another matter.
A government attempting to purge everyone who worked under Assad would destroy much of the human capital required to govern.
Iraq after 2003 provides the obvious warning. The American-led occupation dismantled much of the Ba’athist state and disbanded the Iraqi army, producing hundreds of thousands of armed and politically excluded men while weakening administrative capacity. That was not the sole cause of the insurgency and sectarian conflict that followed, but it contributed substantially to the vacuum.
Syria should avoid repeating that error.
De-Assadification cannot become de-statification.
This is especially important because Syria is extraordinarily fragmented.
HTS controls Damascus and much of western Syria.
Kurdish-led forces remain powerful across substantial territory in the northeast.
Turkish-backed armed groups operate elsewhere.
Turkey possesses major influence in northern Syria.
American forces remain deployed in parts of the country.
Israel has moved forces into the buffer zone near the occupied Golan Heights and launched extensive strikes against Syrian military assets following Assad’s collapse.
Russia still possesses military bases.
Different local armed organisations control different communities.
Assad’s departure therefore has removed the actor claiming sovereignty over the entire state without immediately producing another actor capable of exercising it.
This is fragmented sovereignty in its most literal form.
Maps can show one internationally recognised country while coercive authority is divided among several organisations.
The first task of Syrian reconstruction is therefore political consolidation without simply replacing Assad’s dictatorship with another monopoly created through force.
That requires negotiations over how armed groups enter national institutions.
The Kurdish question will be particularly difficult. The Syrian Democratic Forces, dominated militarily by Kurdish organisations, built autonomous institutions in the northeast during the civil war and became America’s principal local partner against Islamic State. Turkey considers important Kurdish components of the SDF linked to the PKK, which Ankara regards as a terrorist organisation.
A new Syrian government therefore inherits a three-way problem.
Kurds want meaningful autonomy and security.
Turkey wants Kurdish armed groups weakened.
Damascus will want territorial sovereignty restored.
Those objectives overlap only partially.
This is where federalism or decentralisation may become useful. A centralised Syrian state has historically struggled to accommodate ethnic and sectarian diversity. Giving regions meaningful local authority could reduce the stakes of controlling Damascus.
But decentralisation creates another fear: temporary autonomy can become permanent partition.
Turkey fears a Kurdish political entity on its border.
Arab nationalists may fear disintegration.
The new government therefore needs to make local autonomy compatible with national sovereignty.
This is constitutional engineering, not battlefield strategy.
Syria’s religious minorities face an even more immediate test. Assad presented his regime internationally as a protector of minorities, particularly Alawites and Christians, against Sunni Islamist extremism. That narrative was partly self-serving because fear of sectarian retaliation helped bind minorities to the regime.
HTS now needs to prove that Assad was wrong.
Statements promising protection are useful.
Behaviour matters more.
If Alawite civilians are collectively punished because Assad’s family belonged to their community, Syria risks reproducing the sectarian logic that sustained the civil war.
Collective responsibility would be disastrous.
An Alawite shopkeeper is not responsible for Assad’s prisons.
A Christian family is not responsible for Russian air strikes.
A Sunni citizen is not responsible for jihadist atrocities.
Individual criminal responsibility is the only sustainable foundation for transitional justice.
This will be difficult because Syria contains enormous accumulated grievances. The Assad government imprisoned, tortured and killed opponents on a massive scale. Families have spent years searching for relatives who disappeared into detention centres. As prisons have opened this week, Syrians have begun discovering more evidence of the regime’s detention system.
Demands for justice therefore are not abstract.
But justice needs institutions.
If revenge occurs through militias or crowds, punishment becomes determined by identity and accusation.
If prosecutions occur through courts using evidence, responsibility can become individual.
That distinction may determine whether Syria escapes the logic of civil war.
The economic situation makes everything harder. Years of fighting destroyed infrastructure and displaced millions of people. More than six million Syrians became refugees abroad and millions more were internally displaced during the conflict. Large parts of the economy became dependent on aid, informal trade and wartime networks.
Removing Assad therefore does not restore the pre-war economy.
Capital has been destroyed.
Human capital has emigrated.
Sanctions remain.
Property ownership is contested.
Infrastructure requires enormous reconstruction.
The new government will need external financing quickly.
This gives Western and Gulf governments substantial leverage.
Sanctions originally designed to pressure Assad can now become obstacles to reconstruction if they remain unchanged after the political conditions that justified them disappear.
But lifting sanctions immediately without conditions would surrender leverage before the new political system reveals its direction.
This creates a conditionality problem.
Western governments can offer phased sanctions relief in exchange for minority protection, political inclusion, counterterrorism commitments and progress towards credible elections.
Too little relief and the economy remains trapped, weakening moderate governance.
Too much relief immediately and external leverage disappears.
The optimal strategy is gradual and measurable.
The same principle should guide the question of HTS’s terrorist designation.
The organisation’s history cannot simply be forgotten because its leader now uses more moderate language.
But political actors can change.
Institutions should therefore evaluate current behaviour rather than permanently freezing identity according to origin.
Does HTS permit other political groups to organise?
Does it protect minorities?
Does it prevent revenge killings?
Does it allow women meaningful participation?
Does it dismantle transnational jihadist networks?
Does it move towards elections?
Those outcomes should determine international engagement.
This is more useful than either immediate normalisation or permanent exclusion.
Assad’s fall also represents a profound strategic defeat for Iran.
Syria was the geographical bridge connecting Iran to Hezbollah in Lebanon. Iranian weapons and personnel moved through Syrian territory, giving Tehran a corridor of influence extending from Iran through Iraq and Syria towards the Mediterranean.
That network has now been severely disrupted.
Hezbollah is weakened.
Assad is gone.
Iran’s regional deterrence strategy therefore has suffered another major loss.
This may alter the broader Middle Eastern balance more significantly than Assad’s removal itself.
Iran increasingly needs to rely on its own missile capabilities and remaining partners rather than the network of territorial influence it spent decades constructing.
Again, successful Israeli operations against Hezbollah and Iranian infrastructure have produced second-order effects by changing what other actors can sustain.
Russia also loses strategically.
Its intervention in 2015 was one of the clearest demonstrations that Moscow could project military power beyond the former Soviet space and preserve an allied government despite Western opposition.
Nine years later, that achievement has largely disappeared.
Russia retains interests in the Tartus naval facility and Hmeimim airbase, but their future now depends on negotiations with Syria’s new authorities.
The Ukraine war therefore creates another opportunity cost.
Military resources committed in one theatre reduce flexibility elsewhere.
Great powers are powerful.
They are not infinitely powerful.
This is the resource constraint behind multipolarity.
Russia can sustain enormous effort in Ukraine.
Doing so makes simultaneous commitments more difficult.
Iran can support Hezbollah, Assad, Iraqi militias and the Houthis.
Weakening several components simultaneously stretches the network.
Strategic systems that appear formidable individually can become fragile when challenged across several fronts at once.
Turkey emerges as one of the largest potential winners. Ankara supported Syrian opposition groups, hosts millions of Syrian refugees and possesses substantial influence over northern Syria.
Assad’s collapse gives President Recep Tayyip Erdoğan greater leverage over the country’s political future.
But victory creates responsibility.
Turkey now needs a stable Syria enough for refugees to return voluntarily, Kurdish security concerns to be managed and cross-border trade to recover.
An unstable post-Assad Syria would impose enormous costs on Turkey despite weakening a former adversary.
This is the recurring lesson of regime collapse:
your enemy disappearing does not guarantee your preferred order appears.
The United States discovered it in Iraq.
NATO confronted it in Libya.
Regional powers may now confront it in Syria.
This is why celebrations of Assad’s fall should remain separate from predictions about Syria’s future.
The first can be morally understandable without making the second optimistic automatically.
A brutal government has collapsed.
Political prisoners have been released.
Millions of displaced Syrians can imagine returning to a country without Assad.
Those are extraordinary developments.
But revolutions create possibility, not predetermined progress.
Syria could become more pluralistic.
It could fragment further.
HTS could moderate through governing responsibility.
It could consolidate another authoritarian system.
Regional powers could cooperate around stability.
They could turn Syria into another arena for proxy competition.
All remain plausible.
The next several months will therefore matter more than the dramatic images from Damascus.
The indicators worth watching are relatively simple.
Do revenge killings decline?
Do ministries continue functioning?
Are minorities protected?
Do armed groups begin integrating into national structures?
Does the interim government broaden beyond HTS?
Do refugees begin returning voluntarily?
Are sanctions relaxed in response to measurable reforms?
Does Syria move towards elections rather than indefinitely extending revolutionary government?
These questions measure institution-building rather than regime destruction.
Assad’s government failed spectacularly at the end because much of its apparent strength depended on fear, external military support and institutions hollowed out around one ruling network.
The lesson for whoever replaces it should be obvious.
A state is strongest when citizens have reasons to preserve it even when they dislike the government.
Assad constructed the opposite.
When his allies weakened and his army stopped fighting, remarkably little remained between the regime and collapse.
Syria now has an opportunity to build something more durable.
That requires accepting a principle Assad never did:
the state cannot belong permanently to the people who happen to control it today.
His regime lasted more than two decades.
His family’s rule lasted more than half a century.
Its collapse took days.
The next Syrian political order should judge its success not by whether it can survive that long through coercion, but by whether it can create institutions strong enough that governments can change without the state collapsing with them.
