One year has passed since the start of coalition air strikes against ISIL in Syria. Over that year ISIL has endured setbacks and defeats in a number of areas, perhaps the most important of which are Ain al-Arab (Kobani) and Hasaka. However, it succeeded in expanding its influence and incorporated new towns and villages such as Tadmur, the eastern Rif Homs, northern Rif Aleppo, Qalamon, and the Yarmouk refugee camp in the capital into its “state”. In this way it cut up the majority of Syrian territory and threatened strategic centers and urban areas such as Homs and the capital Damascus. The paper concludes that ISIL is imposing the rhythm and variables of battle in various parts of Syria. The international coalition remains unable to eliminate it or degrade it in the short or medium term. Eliminating ISIL may take years if the piecemeal US approach to confronting it continues as now.
