事实上，美国永远准备谈判条约，但很少愿意签署 — — 批准的情况就更少了 — — 这使得美国仍游离于京都议定书、禁止地雷公约和联合国海洋法宣言等全球协定之外。
Indeed, always ready to negotiate treaties but rarely prepared to sign – and even less likely to ratify – them, the US remains absent from such key global agreements as the Kyoto Protocol, the Mine Ban Treaty, and the UN Convention on the Law of the Sea.
