冷战结束后 ,美国国内兴起了一股新的孤立主义思潮 ,要求减少美国在海外的义务 ,集中精力解决国内问题。但新孤立主义遭到了国内新干涉主义者、理想主义者甚至现实主义者的批评。批评者们认为 ,冷战后的世界依然面临着种种威胁 ,美国为了自己的安全与利益 ,应该继续担当领导世界的责任 After the Cold War ended, a new trend of isolationism emerged in the United States, calling for the reduction of U.S. obligations abroad and concentrating on solving domestic problems. But neo-isolationism has been criticized by new neo-interventionists, idealists and even realists. Critics believe that the post-Cold-War world still faces threats.
