Syrian Democratic Forces announce end of operations after years battling ISIS

The Syrian Democratic Forces (SDF), a coalition of Kurdish, Arab and Assyrian militias that became the primary ground force against the Islamic State, announced this week that it will formally disband. Formed in 2015 under the umbrella of the US‑led anti‑ISIS campaign, the SDF captured key territories in northern and eastern Syria, including the oil‑rich city of Raqqa, and played a decisive role in the caliphate’s collapse.

The decision follows a series of strategic setbacks. The United States announced a complete troop withdrawal from northeastern Syria in early 2024, ending the logistical and air‑support lifeline that had underpinned SDF operations. Simultaneously, Turkey intensified cross‑border incursions, targeting Kurdish elements the SDF considered allies. These pressures, combined with internal political negotiations in Damascus, have left the coalition without a clear security partner.

SDF leadership cited the need to prevent further civilian casualties and to avoid a power vacuum that could be exploited by extremist groups or foreign forces. In a brief statement, commanders said members would either integrate into local police structures, join civilian life, or relocate to areas where they could continue community defense under new arrangements.

The dissolution raises concerns about the future of stability in Syria’s northeast. International observers warn that the absence of a unified militia could embolden remnants of ISIS and complicate reconstruction efforts. Meanwhile, the Kurdish political wing, the Syrian Democratic Council, has pledged to pursue a political solution through dialogue with Damascus, seeking autonomy guarantees within a federal framework.

For now, the SDF’s exit marks the end of a chapter that reshaped the Syrian battlefield. The coalition’s legacy includes the liberation of millions from extremist rule, the establishment of semi‑autonomous administrations, and a complex relationship with global powers that will influence the region’s trajectory for years to come.
