In short, US foreign policy may be as active as ever, but it is downsizing and becoming more exacting about its priorities. As a result, many global challenges – climate change, trade, resource scarcity, international security, cyber-warfare, and nuclear proliferation, to name a few – are bound to loom larger.
简而言之，美国的外交政策或许亦然像从前那样积极，但免不了正在走下坡路，越来越难以维持其超然的地位。结果，诸多全球性挑战——气候变化、贸易、资源稀缺性、国际安全、网络战、核扩散等等——将注定愈演愈烈。
