奥巴马宣布，叙利亚使用化学武器将跨越“红线 ” — —并暗示如果越线将动用武力 — — 这反映了美国过去四十年来所形成的在世界范围内推行人权的承诺。
Obama’s proclamation that the use of chemical weapons in Syria would cross a “red line” – and his implicit threat to use force if that line were crossed – reflects the commitment that the US has made during the past four decades to promote human rights worldwide.
