In fact, certain advocates of US intervention – both neo-cons and “liberal hawks” – seem to desire the opposite outcome; they want a war against Iran. And there is probably a clear link in Obama’s mind between the red line in Syria and the one he has drawn for Iran, perhaps equally unwisely, to prevent it from developing nuclear weapons.
我们根本无法确定美国干预会降低战火蔓延的风险。事实上，美国干预的某些倡导者（包括新保守主义者和“自由主义鹰派”）似乎都更期待出现相反的结果；他们希望对伊朗开战。奥巴马心中或许为伊朗划定了与叙利亚相似的红线（这两条红线同样不明智），那就是阻止伊朗的核武器研发。
