Indeed, assuming that Assad does not start bulldozing entire cities, I cannot imagine any circumstances under which the US would support even limited military intervention in Syria without public approval by the Arab League and Turkey. That is why we have seen a game of “after you” with respect to Syria, with the Turks saying that they need Western support, the US saying that it needs regional support, and both saying that they need UN support.
事实上，假设巴沙尔不会将各城市整个夷为平地，我无法想象美国会在阿盟和土耳其不点头的情况下支持哪怕是有限的军事干预叙利亚。这就是我们在叙利亚问题上看到一个“你先动”博弈的原因，土耳其说它需要西方支持，美国说它需要该地区支持，而土美均说它们需要联合国支持。
