Ce qu’a été cette campagne
A decade-long Turkish effort to shape the Syrian side of its border, pursued through three ground operations between 2016 and 2019 and since then through the factions and administration they left behind. Its objective is a condition rather than a territory — no autonomous Kurdish armed force in Syria.
Türkiye is the only outside power in Syria that holds ground with governance attached, and this campaign is how it got there. That accumulated position is the source of its leverage over the transition and over the terms of the northeast settlement, and it is the reason the northern file cannot be closed by any agreement to which Ankara is not effectively a party. The campaign also explains a demographic fact the module records repeatedly: the population movement along the northern belt since 2016 is a consequence of these operations, not a background condition.

Synthèse
Türkiye entered the Syrian ground war to shape its border rather than to decide the capital. Euphrates Shield in 2016–17 cut ISIS from the frontier and blocked the Kurdish-led cantons from linking; Olive Branch took Afrin in 2018, displacing much of its Kurdish population; Peace Spring in October 2019, launched into the space left by a US pullback announcement, took the strip between Tal Abyad and Ras al-Ayn and pushed the SDF into its first security arrangement with Damascus and Moscow. Alongside the operations, Ankara organised the factions it backed into the Syrian National Army and built administration, currency and trade links into its zones — an influence infrastructure that outlived the war. Since 2020 the campaign has been static militarily and active politically: Ankara welcomed the SDF's retreat in 2026 but treats its core demand as a matter of implementation rather than signature.
Objectifs déclarés
Ce que disent les participants. Chaque entrée cite où la position a été exprimée ; Vigil consigne qu’elle a été exprimée, non qu’elle est vraie.
Türkiye states its objective as the prevention of a contiguous Kurdish-led armed entity on its southern border, which it considers an extension of the PKK, and the creation of conditions for the return of Syrian refugees from Türkiye.
Recorded as Ankara's stated position. The module does not adopt any party's characterisation of another as a terrorist organisation.
Objectifs évalués
La lecture de Vigil, assortie d’un degré de confiance. Tenue structurellement à l’écart des positions déclarées, afin qu’une évaluation ne puisse jamais être publiée comme l’objectif déclaré de quelqu’un.
Establish a permanent veto over the political status of northern Syria, exercised through territorial presence and local administration rather than through diplomacy alone.
Build a Syrian client structure — armed, administrative and economic — durable enough to represent Turkish interests in whatever settlement eventually emerges.
Convert refugee return into a strategic objective as well as a domestic political one, by creating administered areas inside Syria capable of receiving returnees.
The stated intent is documented; the extent to which the zones were organised around it, rather than it being invoked for them, is not.

The dissolution of the YPG as an autonomous armed force is the campaign's specific objective, which is why it is named as a participant separately from the umbrella it sits under.

Organised under Turkish patronage during the operations and the administrative instrument of the zones since. Announced as absorbed into the new Ministry of Defence structures in January 2025; the degree of actual integration varies by faction.
Parties touchées
- Forces de l’État syrien (ministère de la Défense) Partie touchée · Confiance : modérée · au 2026-07
The transitional government inherits a northern border it does not fully administer, and a set of arrangements it did not make.
Euphrates Shield
The first ground operation cut ISIS from the border and, in the same movement, blocked the Kurdish-led cantons from linking across the western Euphrates. The dual purpose is the campaign's signature: counter-ISIS in form, counter-YPG in effect.
Olive Branch — Afrin
Afrin was taken from the YPG, and much of its Kurdish population displaced. The isolation of Afrin from the rest of the Kurdish-populated north — a terrain fact — is why it could be taken separately and why the displacement was not reversed.
Peace Spring and the realignment
Launched into the space left by a US pullback announcement, the operation took the Tal Abyad–Ras al-Ayn strip and pushed the SDF into its first security arrangement with Damascus and Moscow. It established that the northeast's autonomy depended on an external guarantee that could be withdrawn.
The zones, and the frozen line
Militarily static and politically active: administration, currency, trade and services were built into the Turkish-influenced areas, converting military positions into an influence infrastructure that survived the war and outlived the government it was built against.
The demand, pursued through other people's agreements
Ankara welcomed the SDF's retreat and the January 2026 agreement, while treating its core demand as measured by implementation rather than by signature. The campaign's current instrument is leverage over a settlement it is not a party to.
Rebuilding the Syrian army, and where another power stops it
The 13 August 2025 joint training and advisory memorandum turned Turkish influence from a border position into a stake in the Syrian state's military reconstruction — training, planning, weapon systems and logistical materiel, with Syrian units at Turkish facilities and in EFES-2026 by May 2026. That project has a boundary set by a third party. Israel struck the T4, Palmyra and Hama airfields in March and April 2025 while Turkish teams were surveying them for the prospective pact, and struck Abu al-Duhur in eastern Idlib on 18 August 2026 citing an imminent Turkish deployment that Ankara and Damascus both deny. The second strike arrived with no warning through the Azerbaijan-brokered military channel the two states have used since April 2025, after which Washington began proposing a standing trilateral deconfliction arrangement. On 14 August 2026 Türkiye removed a former YPG commander now serving as Syria's assistant defence minister from its most-wanted list — the same project seen from the other side, and the first case of Ankara applying its integration test to a named person.
Issue et situation actuelle
Ongoing, with the military phase over and the political objective unmet on paper. Türkiye holds a belt of northern Syria with administration attached and a client force structure inside the new state's nominal order, and it obtained in 2026 the outcome its operations had been unable to force: a Kurdish-led military authority dissolving into a Syrian state structure. Whether that satisfies the demand depends on implementation of an agreement Ankara did not sign, which is why the campaign has no end date and its own commander's measure of success is somebody else's compliance.
Adaptations observées
A shift from ground operations to administration as the instrument of influence after 2019 — currency, services, schooling and trade integrated into the zones, producing durable position without further operations.
Substitution of leverage over a third-party settlement for direct action after 2025, once a transitional government in Damascus offered a route to the same objective at lower cost.
Implications politiques
Any northern settlement that Ankara does not accept is provisional, which gives an external power an effective veto inside Syria's internal constitutional question.
Implications militaires
The dissolution of an autonomous Kurdish armed force is a demand about structure rather than territory, so it can be satisfied or frustrated by administrative arrangements rather than by fighting.
Implications économiques
The administered zones run on Turkish currency, trade and services, so the reintegration of the north is an economic convergence problem as much as a political one.
Implications humanitaires
The population movement produced by these operations — most sharply at Afrin in 2018 — is one of the module's largest unreversed displacement events, and property and return questions there remain open.

Couches de référence
Ce qui reste inconnu
- The scale, depth and disposition of the Turkish military presence in northern Syria is not published in this module and nothing here should be read as describing it.
- Displacement figures arising from the 2018 and 2019 operations vary between sources and remain contested; the record states direction and magnitude rather than a number.
- The command relationship between Turkish authorities and individual factions varies and is reported rather than established, which is why the supporting edge carries a note rather than a stronger grade on its specifics.
- Whether Ankara regards the January 2026 agreement's implementation as satisfying its demand is not established, and official statements on it have been deliberately conditional.
Lectures que les éléments permettent aussi
- The campaign can be read as a security policy driven by the PKK question, as a domestic political programme driven by the refugee file, or as an opportunistic accumulation of position in a collapsing neighbour. The operations' timing is consistent with all three, and the module records the stated objective and the assessed ones separately for that reason.
- The 2026 outcome can be read as vindication of a decade of pressure or as an incidental benefit of a US-brokered settlement Ankara neither designed nor controlled.
Figure ici parce que l’évaluation propre à la fiche n’est pas la seule que ses sources permettent — et non comme une réserve sur l’évaluation ci-dessus.
Dispositif des forces turques dans le nord
Posture is the measurable expression of whether Ankara treats the 2026 agreement's implementation as satisfactory. It moves before the rhetoric does.
Si l’administration des zones converge avec celle de l’État
Currency, schooling, policing and customs in the Turkish-influenced areas are the practical test of whether the north is rejoining a single country.
Le processus de dissolution du PKK
The Syrian file and the wider process are treated as connected by every party to them, and movement in one has repeatedly preceded movement in the other.
