In the case of Syria, Putin’s objectives are two-fold. First, he wants to ensure that Assad, a longtime Russian ally (and buyer of Russian weapons), is not toppled. Last fall, rebel forces were advancing and threatening Assad’s grip on power. No longer. The Russian intervention was ostensibly supposed to attack Islamic State. In fact, some 90% of Russian sorties have been directed not at its strongholds but at more moderate rebel groups backed by the United States. This has enabled Assad to regain part of Aleppo province and to consolidate his hold on an eastern corridor running from Damascus to the Mediterranean Sea. MORE
