Consider the US, which has refused to join key international treaties – for example, the 1982 United Nations Convention on the Law of the Sea (UNCLOS), the 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses (which has not yet entered into force), and the 1998 International Criminal Court Statute. Indeed, unilateralism remains the leitmotif of US foreign policy, and this is also reflected in its international interventions, whether cyber warfare and surveillance, drone attacks, or efforts to bring about regime change.
以美国为例，美国一直拒绝签署重要的国际公约——其中包括1982年的联合国海洋法公约（UNCLOS）、1997年的联合国国际水道非航行使用法公约（该公约目前尚未生效），以及1998年的国际刑事法院规约。事实上，单边主义依然是美国外交政策的主旋律，这也体现在包括网络战、监控、无人机袭击或者以政权更迭为目的的国际干预行动之中。
