But, while none of these powers represents a serious alternative to America’s global role, the US will no longer be able to act unilaterally, as it did after the Cold War’s end, and it will be weakened substantially. This change has become particularly obvious in the Middle East and the Asia-Pacific region.
但尽管这些国家还没有谁能真正取代美国的全球作用，美国也不能再像冷战后那样单方面行动，其实力也将受到大幅度削弱。上述变化在中东和亚太地区体现得尤其显著。
