Earlier this week, American jets began bombing targets inside Syria, signaling a new phase in the battle against the Islamic State (also known as ISIS). Kenneth M. Pollack, senior fellow at the Center for Middle East Policy, argues that although the Obama administration’s strategy against ISIS still lacks a number of critical components, a comprehensive overall strategy is in fact emerging. According to Pollack, President Obama and top U.S. military brass have recognized that ISIS is merely a symptom of a much larger problem that has engulfed Iraq and Syria.
