The Road to ar-Raqqah: Background on the Syrian Democratic Forces

The composition and behavior of the force that recaptures ar-Raqqah City will in part determine the long-term success of the U.S.-led anti-ISIS campaign in Syria. The Syrian Democratic Forces (SDF) is the U.S.’s most effective partner fighting ISIS in Syria, but it has limitations that risk undermining the gains it makes on the ground. The SDF, although dominated by the Syrian Kurdish People’s Protection Units (YPG), is not monolithic.

Turkish Incursion into Northern Syria Signals Turning Point in Anti-ISIS Fight

Turkey is unraveling America’s anti-ISIS partner in northern Syria in order to position itself as a major power broker in planned operations to retake Raqqa City. Turkish Armed Forces (TSK) crossed into Syria to seize the ISIS held border town of Jarablus alongside numerous Turkish- and U.S.-backed Syrian armed opposition groups on August 24.

ISW Resources on Jabhat Al- Nusra: Al-Qaeda's Syrian Affiliate

Since 2014, ISW has been tracking Jabhat al- Nusra, the official al- Qaeda affiliate in Syria. ISW believes that Jabhat al- Nusra poses one of the most significant long-term threats of any Salafi- jihadi group. ISW recognizes ISIS and al Qaeda are Salafi- jihadi military organizations with distinct sources of strength and maintains that U.S. strategy must operate against both ISIS and Jabhat al- Nusra simultaneously. Focusing on an "ISIS first" strategy will result in Nusra continuing to grow stronger.

The Competing Campaigns Against ISIS in Northern Syria

ISIS currently faces an unprecedented threat to its core terrain in Northern Syria from an array of competing actors. Nonetheless, the degrading position of ISIS in Northern Syria is poised to ignite further conflict. The terrain vacated by ISIS will likely host renewed competition between Syrian Kurds, opposition groups, and pro-regime forces as well as a geopolitical struggle involving Turkey, Syria, Russia, and the U.S. These conflicts could stall further progress against ISIS in Syria.

ISIS Collapses Opposition Frontline in Northern Aleppo Province

The Islamic State of Iraq and al-Sham (ISIS) has mounted a major offensive against opposition groups in Northern Aleppo Province, threatening the total collapse of the last pocket of opposition-held terrain along the Syrian-Turkish Border. The looming defeat of the opposition on the Mare'a Line poses a significant risk to the long-term success of the anti-ISIS campaign by foreclosing future partnership with Sunni Arabs in Northern Syria and deepening U.S. overreliance on the Syrian Kurdish YPG

Russia and Turkey Escalate: Russia’s Threat to NATO Goes Beyond Eastern Europe

Russia is waging a multi-front campaign against Turkey in order to weaken NATO in line with its strategic objectives. The use of a high-end Soviet-era MANPADS against a Turkish helicopter in southeastern Turkey on May 13 could indicate that Russia is providing meaningful military support to the Kurdistan Workers' Party (PKK) insurgency. The incident, if indeed an escalation by Russia, is yet another infringement of a sovereign NATO partner.
