In the 1960’s, the British pound was the world’s second reserve currency. American policymakers expended considerable effort devising ways to support the pound, because they knew that the same factors that made the pound vulnerable also threatened the dollar.
当前这种局势在历史上有先例。20世纪60年代，英镑还是世界第二大储备货币。美国的政策制定者费尽心机来支持英镑，因为他们知道削弱英镑的因素同样也威胁着美元。他们把英镑看作美元的外围防线。当时的批评者讥讽这种局面，说是跛脚鸭子搀着跛脚鸭子。
