If the US is to make its financial weaponry an effective foreign-policy tool, big banks cannot blithely proceed to do what US authorities have prohibited. It would take only a few noncompliant banks to render financial sanctions ineffective.
如果美国想把其金融武器变成一项有效的外交政策工具，大型银行就无法毫无顾忌地从事当局禁止的行为。证明金融制裁的无效性只需要一些不服从的银行就够了。但同时也无法去探测哪些银行没有服从以及违规到何种程度。
