However, if you do have enemies, I have some advice for you. "Keep your friends close and your enemies closer." Many believe the Chinese military genius, Sun Tzu, wrote something like this in his book The Art of War. Others say Machiavelli wrote this sentence in The Prince._________________________"My father taught me many things here. He taught me in this room. He taught me, 'Keep your friends close but your enemies closer.'" Scene from "The Godfather II"不过,如果你有敌人,那么我有几点建议给你. "密切关注你的朋友,更要密切关注你的敌人."很多人都相信中国伟大的军事家孙膑.在<孙子兵法>中也写有类似的说法.还有人说马基雅维利在<君主论>中也写过类似的话._________________________"我爸爸在这间房子里教会了我很多事.他教会了我,'密切关注你的朋友,更要密切关注你的敌人.'" 场景来源于<教父2>
