ISW has produced nearly 60 maps on Russian airstrikes in Syria since they first began on September 30, 2015. The first map appeared less than 24 hours after the Russians began strikes and they continue today as do the strikes despite a declared "cessation of hostilities" and an alleged Russian withdrawal.
Russia continues to pressure the U.S. and regional actors into closer cooperation through its military intervention in Syria. Russia ultimately seeks to supplant the U.S. as a security guarantor in the Middle East and has used its air campaign in Syria to galvanize its demands for greater coordination in the theater.
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.
The tempo of Russian air operations has dramatically escalated in Syria. The rate and breadth of Russian airstrikes nearly tripled from May 29 – June 2 in comparison to the previous five day period. ISW was able to assess a total of 29 Russian airstrikes with low and high confidence beginning on May 29 and only 10 locations from May 24 -28.
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 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.
Syrian President Bashar al-Assad and his allies have set the stage for an imminent offensive to complete the encirclement of Aleppo City. If successful, this could deliver a decisive blow to the powerful armed groups in Aleppo City that drives the opposition towards radicalization and a merger with Syrian Al-Qaeda affiliate Jabhat al-Nusra.
