In other words, in a G-Zero world, an increasingly aggressive global environment makes the US all the more appealing to countries seeking to hedge their bets.&nbsp;As a result, the US has an opportunity to act more precisely in its own interests. Supplying less leadership allows the US to weigh opportunity costs before taking action, and to select the issues and circumstances that suit it the best.&nbsp;In this environment, military intervention in Libya does not necessitate the same in Syria.
换句话说，在G0世界中，越来越波起云涌的国际环境使得美国对不想孤注一掷的国家的吸引力更大了。结果，美国赢得了更精确地按自己利益行事的机会。减弱领导者角色让美国得以在行动前掂量机会成本，选择最合适自身的问题和环境展开行动。在这样一种环境下，军事干预利比亚和叙利亚不可同日而语。
