The attention of US President Barack Obama is centered on matters of great importance, such as the Middle East, his evolving strategy in Afghanistan, and the struggling American economy. The same is true of the EU, where attention – and action – has been centered in recent months on defending the euro and resolving the economic difficulties on the Union’s periphery.
问题是，尽管多边主义已经是大势所趋，但由于因为一个全球领导角色的缺失，单边主义依然可能复辟。美国总统奥巴马的注意力都放在了许多重要的事务上，比如中东问题，阿富汗干涉战略以及拯救美国经济。类似的情况也发生在欧盟身上，比如最近欧元保卫战以及应对外围国家的经济问题。
