In Syria, whose side is the United States on? (Fareed Zakaria) from the Washington Post
"Whom is the United States for in this struggle? ... The West is against almost every major group fighting in Syria, which makes for moral clarity but strategic incoherence. ... The U.S. Army could easily defeat the Islamic State, which has a lightly armed force of fewer than 30,000 men. But then it would own real estate in Syria. Who wants to govern that territory, protect the population and be seen by locals as legitimate?"
