 在这条道路上迈出的一大步是美国与俄罗斯的《新裁武条约》，该《条约》到 2018 年 2 月得到全面实施时，将把美国和俄罗斯部署的战略核弹头的最高数目限制在 1 550 枚这一自1950年代后期以来的最低水平。
• A major step along this path is the U.S.-Russia New START Treaty, which when fully implemented by February 2018 will cap U.S. and Russian deployed strategic warheads at 1,550, the lowest levels of these weapons since the late 1950s.
