Syria Grapples with Chemical Weapons Legacy and Escalating Clashes as UN and US Push for Stability
New York/Beirut – Amid ongoing instability in Syria, the United Nations has called for international unity to eliminate the country's lingering chemical weapons program, describing the moment as a "critical opportunity." Simultaneously, the White House has reaffirmed U.S. President Donald Trump's commitment to a "stable, unified" Syria, as Syrian Democratic Forces (SDF) intensify attacks in Aleppo province, highlighting persistent geopolitical tensions more than a decade into the Syrian civil war.
The UN's appeal came on Thursday from Izumi Nakamitsu, Under-Secretary-General and High Representative for Disarmament Affairs, who addressed the Security Council on the Syrian Arab Republic's obligations under the Chemical Weapons Convention (CWC). "There is currently critical opportunity to obtain long-overdue clarifications on full extent and scope of Syrian chemical weapons program and to rid country of all chemical weapons," Nakamitsu stated, according to Anadolu Agency. This push follows years of allegations against the regime of President Bashar al-Assad for using chemical agents, including sarin and chlorine, in attacks that killed hundreds of civilians during the conflict.
Syria joined the CWC in 2013 following the Ghouta chemical attack near Damascus, which claimed over 1,400 lives and prompted international outrage. Under a U.S.-Russia-brokered deal, Damascus declared 1,300 metric tons of chemical agents, most of which were reportedly destroyed at sea or abroad. However, the Organisation for the Prohibition of Chemical Weapons (OPCW) has repeatedly accused Syria of non-compliance, citing undeclared stockpiles, production facilities, and use in violations post-2013, such as the 2017 Khan Shaykhun attack. The UN official's remarks underscore a rare window for progress, possibly linked to shifting regional dynamics, though details on catalysts remain unclear.
In parallel developments, violence has surged in northern Syria, particularly Aleppo, where SDF fighters— a U.S.-backed, Kurdish-led coalition controlling much of the northeast—have escalated operations. The White House responded to these clashes on Thursday, with a senior official telling Anadolu Agency: "President Trump is committed to supporting a Syria that is stable, unified, and at peace with itself and its neighbors."
Aleppo, Syria's pre-war economic hub, has been a flashpoint since rebels seized eastern districts in 2012, only for regime forces, backed by Russia and Iran, to retake them in 2016-2017. Today, the province sees overlapping conflicts: Turkish-backed Syrian National Army (SNA) factions clash with SDF units amid Ankara's concerns over Kurdish separatism, while Hayat Tahrir al-Sham (HTS), an Islamist group dominant in Idlib, exerts influence nearby. Recent SDF advances reportedly target SNA positions, displacing civilians and raising fears of broader escalation. These attacks coincide with fragile ceasefires and U.S. troop presence in SDF areas to counter Islamic State remnants.
Background: Syria's Fractured Geopolitics
Syria's 13-year civil war, sparked by pro-democracy protests in 2011, has killed over 500,000 people, displaced millions, and drawn in global powers. Assad retains control of roughly two-thirds of the country with Russian airpower and Iranian militias, while SDF holds oil-rich eastern territories, HTS governs Idlib, and Turkish proxies control border enclaves. Chemical weapons remain a sore point; the OPCW's Investigation and Identification Team has attributed attacks to Assad's forces as recently as 2018.
U.S. policy under Trump has oscillated: his first term saw troop drawdowns but strikes on regime targets after chemical incidents. The current administration's emphasis on unity aligns with broader Middle East realignments, including the Abraham Accords and efforts to isolate Iran. However, SDF escalations risk complicating U.S.-Turkey relations, NATO allies with competing Syrian agendas.
The UN's timing may reflect diplomatic momentum, potentially tied to stalled political talks under UN Resolution 2254, which calls for a constitutional process and elections. Russia's 2022 Ukraine invasion has strained its Syrian commitments, while Iran's proxies face Israeli strikes, creating vacuums.
Outlook: Pathways to De-escalation?
As SDF clashes threaten to unravel ceasefires brokered by the U.S., Turkey, and Russia in 2019, stakeholders face pressure to prioritize diplomacy. The White House statement signals Washington's intent to mediate, but without specifics on support mechanisms—military aid, sanctions relief, or reconstruction—it remains aspirational.
Nakamitsu urged "unity" among Security Council members, fractured by vetoes from Russia and past U.S.-led actions. Progress on chemical disarmament could build trust for wider talks, but Assad's reluctance and rebel fragmentation pose hurdles. With over 90% of Syrians in poverty per UN estimates, humanitarian crises compound security woes.
International observers warn that missed opportunities could perpetuate cycles of violence. For now, Syria's geopolitics hinge on whether global calls for stability translate into coordinated action amid Aleppo's battlegrounds and the shadow of chemical stockpiles.
