    27. 当德国和英国战舰1902年向长期负债累累的委内瑞拉行进，准备强制收回一笔早就逾期的贷款时，罗斯福要求两国保证不得以追债方式寻求领土和政治扩张。但德国代表只承诺放弃永久性占有领土（留下了建立期限99年的租界的可能，如英国在埃及以及英国、德国在中国所做的那样），罗斯福于是威胁发动战争。他随即派一支美国舰队挥师南下，并把委内瑞拉海港的地图发放给媒体。这一策略奏效了。罗斯福保持沉默，好让威廉皇帝保全面子，退出这场危机。这个时候，德意志帝国在委内瑞拉的野心遭到了决定性重创。See Edmund Morris, Theodore Rex (New York: Random House, 2001), 176ndash;82.
