当然在全球政局比较动荡的年代，我们也听到过过诸如，是可忍孰不可忍、悬崖勒马以及勿谓言之不预等较强烈的外交辞令。其中“勿谓言之不预”意为，不要说没有事先跟你说过。指把话说在前面，也就是警告对方事后别后悔。

Of course in an era with a relatively tumultuous political climate, I've also heard stronger diplomatic rhetoric like, "是可忍孰不可忍", meaning "If this is permissible, what isn't permissible?", "悬崖勒马", an idiom mean "to avert disaster in the nick of time" and "无谓言之不预“ meaning, "we have already given fair warning". Suggesting that something has already been said, as a warning to someone else not to regret their actions afterward.
