如果不是当年林肯及其联邦军民与南部邦联的分裂势力作殊死斗争,断然没有美国今天的成就。刻骨铭心的历史记忆和美国社会生存与发展的现实需要,是美国政府将反对分裂国家作为公民效忠的核心理念的深刻原因。 If it was not for the very same kind of struggle that separatist forces Lincoln and his federal soldiers and confederates had with the Confederacy of the South that year, it would be absolutely without the achievements of the United States today. The unforgettable historical memory and the realistic needs of the survival and development of the American society are the profound reasons why the U.S. government will oppose secessionist countries as the core concept of loyalty to citizens.
