The only way to bring Syrian President Bashar al-Assad to the negotiating table is to weaken him and the Islamic State simultaneously. And the only legal or moral justification for striking his air force, ammunition dumps, or heavy weaponry is the international responsibility to protect his people from him – just as the US helped to protect the Yezidis from the Islamic State.
迫使叙利亚总统巴沙尔·阿萨德重回谈判桌的唯一方法是同时削弱他和“伊斯兰国”的力量。打击其空军、弹药库或重型武器装备的唯一合法或道义理由是保护民众免受其伤害的国际义务——就像美国协助保护雅兹迪人免受“伊斯兰国”的迫害一样。
