[单项选择]Shortly after September 11th, President Bush’s father observed that just as Pearl Harbor awakened this country from the notion that we could somehow avoid the call of duty to defend freedom in Europe and Asia in World War Two, so, too, should this most recent surprise attack erase the concept in some quarters that America can somehow go it alone in the fight against terrorism or in anything else for that matter.
