把这一句，留给此刻的你

In a situation where many national leaders do the same thing and look out for national interests, and with an issue like global warming, you're likely to get no solution, so I think you have to have some kind of ethical trump on some of those issues.

在很多国家领导人都在做同样的事情，为国家利益着想的情况下，在全球变暖这样的问题上，你很可能得不到解决方案，所以我认为你必须在这些问题上有某种道德上的特朗普。
