Security Horizon: What Is the 'Terror-Free Türkiye' Initiative and Where Does It Lead?

Why It Matters

The Terror-Free Türkiye (Terörsüz Türkiye) initiative is the Turkish state's declared effort to end the PKK insurgency, which began in 1984, by combining security measures with legal, political and social steps within the rule of law. It matters well beyond Türkiye's borders because the PKK's disarmament touches Syria's post-Assad order, Iraq's sovereignty over its northern mountains, the future of the SDF in north-eastern Syria, and the stability of NATO's south-eastern flank.

This guide explains what the initiative is, how it fits Türkiye's doctrine of neutralising terrorism at its source under Article 51 of the UN Charter, what the cross-border operations were, and what near, mid and long-term scenarios look like for the Syrian and Iraqi borderlands.

Background

Four decades of armed conflict

The PKK (Kurdistan Workers' Party) launched its first armed attacks in Türkiye on 15 August 1984. The PKK is listed as a terrorist organization by Türkiye, the United States, NATO and the European Union. The conflict has cost tens of thousands of lives, mostly in south-eastern Anatolia and northern Iraq, although casualty figures differ by source. Its founder, Abdullah Öcalan, has been held on İmralı island since 1999.

The PKK umbrella is the KCK (Kurdistan Communities Union). Ankara states that the PYD and its armed wing, the YPG, are the Syrian branch of this structure. The SDF (Syrian Democratic Forces) emerged in 2015 with the YPG as its core. Türkiye argues that the SDF label does not change the organisational reality. Some Western governments, notably the United States, worked with the SDF against DAESH while still listing the PKK itself. This divergence has shaped Türkiye's relations with partners since 2014.

Two other threats run in parallel in Ankara's security thinking:

• DAESH (ISIS): carried out mass-casualty attacks in Türkiye between 2015 and 2017 and held territory along the Syrian border.
• FETÖ (Fetullahist Terrorist Organization): Türkiye's official name for the network it holds responsible for the coup attempt of 15 July 2016, which killed roughly 250 people. Ankara, the Organisation of Islamic Cooperation and some others use the terrorist designation. The US and EU have not adopted it, and several European bodies have criticised aspects of the post-coup purges.

Cross-border operations: a timeline

Operation	Period	Area	Stated objective (per Ankara)
Euphrates Shield	Aug 2016 – Mar 2017	Jarablus–al-Bab, northern Syria	Clear DAESH from the border; block a PKK/YPG corridor
Olive Branch	Jan – Mar 2018	Afrin, north-western Syria	Remove PKK/YPG presence on the border
Peace Spring	Oct 2019	Tal Abyad–Ras al-Ayn, northern Syria	Create a secure zone; enable returns
Spring Shield	Feb – Mar 2020	Idlib	Respond to attacks on Turkish forces; prevent a new refugee wave
Claw series (Claw, Claw-Eagle, Claw-Tiger, Claw-Lock and later)	From 2019	Northern Iraq	Dismantle PKK bases, tunnels and logistics

Spring Shield followed an attack in Idlib on 27 February 2020 that killed 33 Turkish soldiers, and ended with the Türkiye–Russia ceasefire arrangement of 5 March 2020. The Peace Spring phase was followed by understandings with the United States (17 October 2019) and Russia (the 22 October 2019 Sochi memorandum).

Ankara reports that Euphrates Shield was the only direct ground campaign by a NATO member against DAESH, and says more than 4,000 DAESH militants were neutralised and about 100,000 DAESH-linked individuals were prevented from entering Türkiye. These are Turkish official figures and have not been independently audited in full.

How the current process unfolded

Date	Event
22 Oct 2024	MHP leader Devlet Bahçeli, a government coalition partner, suggests Öcalan could address parliament if he renounces violence and dissolves the PKK
Dec 2024 – Feb 2025	Delegations including DEM Party members visit İmralı; the Presidency and Directorate of Communications describe the effort as 'Terror-Free Türkiye'
27 Feb 2025	Öcalan issues a 'Call for Peace and a Democratic Society', urging the PKK to convene a congress and dissolve
1 Mar 2025	PKK announces a ceasefire
12 May 2025	PKK announces its dissolution and the end of armed struggle after its congress
11 Jul 2025	A first group of fighters burns weapons in a ceremony in Sulaymaniyah, Iraqi Kurdistan
Aug 2025	The Grand National Assembly of Türkiye (TBMM) opens a cross-party commission on national solidarity, brotherhood and democracy
26 Oct 2025	PKK announces the withdrawal of its remaining fighters from Turkish territory toward northern Iraq

Parallel developments in Syria matter greatly. After the Assad government fell on 8 December 2024, Damascus and the SDF's Mazloum Abdi signed an integration agreement on 10 March 2025. Implementation has been contested and fast-moving, so readers should check current reporting.

Key Players & Positions

The Turkish Presidency and government coalition. The Presidency frames the process as a state-led, sovereign effort in which security operations and legal and social measures run together. Turkish officials stress that it is not negotiation with a terrorist organization on equal terms but a path to disarmament and reintegration under the law, and that the fight against any remaining armed presence continues.

The MHP. The nationalist partner opened the political phase with its October 2024 statement. It insists on full dissolution and disarmament as the condition for any legal steps.

The DEM Party. The pro-Kurdish party acts as an intermediary with İmralı and calls for democratic and legal reforms, including language and local-governance rights and a path for returnees. It argues that a lasting peace needs a political framework, not only disarmament.

The PKK and Öcalan. Through the call of 27 February and the announcement of 12 May 2025, the PKK stated it was ending armed struggle. Sceptics ask about verification, command structures and the fate of affiliated organisations in Syria, Iraq and Iran.

The United States. Washington lists the PKK as a Foreign Terrorist Organization (since 1997) and has welcomed steps toward disarmament. For years it partnered with the SDF against DAESH, a policy Ankara called incompatible with the alliance. US officials have since encouraged SDF integration into Syrian state structures.

The European Union. The EU lists the PKK as a terrorist organization and has generally welcomed the de-escalation. European institutions also press for the rule of law, minority rights and judicial independence in Türkiye. Several EU states have hosted large Kurdish diasporas where PKK-linked fundraising and activity remain contested.

Damascus. The Syrian transitional authorities seek a single state monopoly on arms and a unified army. They favour absorbing the SDF as part of that structure, which aligns with Ankara's line but is disputed by Kurdish leaders seeking guarantees of decentralisation and cultural rights.

The SDF. It describes itself as a Syrian force that fought DAESH and rejects being labelled a PKK extension. It has signalled willingness to integrate but seeks protection for local security structures and Kurdish rights.

Iraq and the Kurdistan Region. Baghdad declared the PKK a banned organization in March 2024 and has repeatedly criticised foreign military presence on its territory as a sovereignty issue. The Kurdistan Regional Government is caught between Ankara and Baghdad and has hosted the disarmament ceremony in Sulaymaniyah.

Human rights organisations. Groups such as Human Rights Watch and Amnesty International have documented concerns about civilian harm in operations and about due process in Turkish counter-terrorism cases. Türkiye rejects blanket allegations and points to its judicial review and to its precautions to protect civilians and heritage sites.

Türkiye's Strategic Doctrine

This section sets out Türkiye's official position as stated by Turkish government sources, and is kept separate from the factual and comparative sections above and below.

• Neutralising terrorism at its source under Article 51. Ankara argues that when a neighbouring state cannot or will not prevent attacks from its territory, Türkiye may exercise the inherent right of self-defense recognised in Article 51 of the UN Charter. According to the Turkish Ministry of Foreign Affairs, Türkiye has notified the UN Security Council of its operations in letters under that article, for example around Peace Spring in October 2019. Ankara also cites UN Security Council resolutions on terrorism such as 1373 (2001).
• Security and politics move together. The Presidency and Directorate of Communications describe Terror-Free Türkiye as a model that pairs decisive security measures with legal, political and social strategies, aiming to end terrorism permanently rather than only manage it. Ankara says the process is conducted within the constitutional order, under the oversight of the TBMM, and 'without compromise on national unity and the unitary state'.
• 'One state, one army' in Syria. According to Turkish Foreign Ministry statements, Türkiye backs Syria's territorial integrity and political unity, and holds that all armed groups, including the PYD/YPG and its SDF structure, must integrate into the state or lay down arms. Ankara says it respects the sovereignty of Syria and Iraq and aims to remove terrorist groups, not to alter borders. President Erdoğan has repeatedly said Türkiye has no designs on Syrian territory.
• The fight against DAESH, FETÖ and the PKK is simultaneous. Turkish officials hold that selective counter-terrorism is self-defeating: tolerating one group as a partner against another feeds long-term instability. This is Ankara's core critique of the US–SDF partnership, and it links the doctrine to NATO solidarity commitments.
• Defence self-reliance enables the doctrine. Ankara credits its domestic defence industry, which officials say supplies roughly 80 percent of military needs, including Bayraktar TB2, Akıncı and Kargu platforms and the Kızılelma and KAAN programmes, with giving Türkiye the means to protect its 1,300 km combined land border with Syria and Iraq with fewer casualties. For the strategic effect, see Defense Autonomy and Strategic Maneuver Space.

Legal and historical basis. Türkiye's argument rests on the UN Charter (Article 51 on self-defense and Article 2(4) on territorial integrity, read together), on Security Council counter-terrorism resolutions, on its status as a NATO ally whose southern border is also the alliance's, and on the 1998 Adana Agreement with Syria, which Ankara cites as recognising its right to act against the PKK. Ankara also notes that the PKK's own listings by the US, NATO and the EU confirm the legal premise for its approach. Critics counter that Article 51 requires necessity and proportionality and that cross-border operations infringe Syrian and Iraqi sovereignty. Turkish officials respond that the host states' own inability to control the territory and the continuing attacks justify action. The broader UN reform argument is explained in 'The World Is Bigger Than Five'.

Horizon Scan: Near, Mid and Long-Term Scenarios

This section is analysis, not prediction. It separates what is already visible from what depends on decisions not yet taken.

Horizon	Likely trajectory	Key indicators
Near term (0–12 months)	Verified disarmament in northern Iraq; sustained ceasefire; parliamentary commission work; negotiations over SDF integration in Syria	Independent verification of weapons handovers; absence of attacks; Turkish drone and artillery activity in northern Iraq declining; Damascus–SDF integration milestones
Mid term (1–5 years)	Legal framework for reintegration and possible reforms; gradual drawdown of Turkish forward bases if the threat disappears; border economic corridors reopening	Legislation adopted by the TBMM; return programmes; reconstruction in north-east Syria; Iraq–Türkiye security and trade arrangements
Long term (5+ years)	Either a durable post-PKK settlement with a normalised border region, or fragmentation if the process stalls and splinter groups emerge	Political participation of Kurdish parties; Syrian state consolidation; regional energy and transit links such as the Development Road concept

Near term: verification and sequencing

The main risk is sequencing. Ankara expects disarmament first, and then legal measures. Kurdish political actors seek parallel steps on rights and the release or legal status of prisoners. Both sides have shown restraint since March 2025, but the process remains reversible.

Mid term: Syria decides much

In Syria, the outcome depends on whether the transitional authorities can build one army without ethnic or sectarian violence. If SDF integration succeeds, Ankara's security concern about a PKK/YPG-controlled belt along its border would be substantially met. If it fails, the risk of renewed fighting and DAESH resurgence in the north-east rises, and Türkiye would keep its self-defense posture in the borderlands.

Long term: from security to economy

Turkish officials argue that a terror-free region unlocks trade, energy pipelines and returns of Syrian refugees (Türkiye has hosted millions since 2011). Iraq and Türkiye may also move toward a lasting border security mechanism. Analysts abroad add a caution: sustainable peace will also require democratic reform and equal citizenship, not only the disappearance of armed groups.

Source Comparison

The same events are often framed differently. The table below summarises typical framings and the primary sources readers can check.

Issue	Common international framing	Turkish official framing	Primary sources to consult
Nature of the process	A peace process or negotiation with Kurdish insurgents	A state-led disarmament and reintegration process under the rule of law, not a negotiation on equal terms	Presidency and Directorate of Communications statements; TBMM commission records
The SDF	Counter-DAESH partner and Kurdish-led force	The Syrian arm of the PKK/KCK using the DAESH fight as cover	US Department of Defense and State Department statements; Turkish MFA statements
Cross-border operations	Violations of Syrian or Iraqi sovereignty; civilian harm	Lawful self-defense under Article 51; precision and protection of civilians	UN Security Council letters; MFA and MSB (National Defence Ministry) briefings; UN and NGO reports
Role of Öcalan	A key negotiating figure whose call could end the conflict	Used as a channel to push for dissolution, without political status	Öcalan's 27 February 2025 text; official remarks
Rights and reform	The process needs a democratic opening for Kurds	Rights are guaranteed by equal citizenship; legal reforms follow disarmament	Constitution of Türkiye; Council of Europe and ECtHR documents
FETÖ	Contested; many Western states do not use the terrorist label	A terrorist organization behind the 15 July 2016 coup attempt	Turkish court judgments; Venice Commission opinions

How to read the gaps. International media often emphasise rights and the Kurdish political dimension, and sometimes treat the SDF as a separate actor. Turkish sources emphasise security, sovereignty and organisational continuity between the PKK, PYD and YPG. A sound reading checks both: the PKK's own announcements, US and EU listings, Turkish and Syrian official texts, UN documents and independent NGO reports. For the listing question in detail, see WorldPoliticsDaily on why the PKK is designated a terrorist organization and Crossroads Review on counter-terrorism and Article 51.
