After a brief war with Spain in 1898, the U.S. controlled several Spanish colonies, Cuba, Puerto Rico, Guam and the Philippines. Officially, the United States encouraged them to become selfgoverning. In reality, the United States kept control. Idealism in foreign policy co-existed with the desire to prevent European powers from acquiring territories that might enable them to project military power toward the United States. Americans also sought new markets in which they could sell their goods. By the end of the 19th century, the U.S. was beginning to emerge as a growing world power.
與西班牙在1898年的短暫戰(zhàn)爭后，美國控制了幾個(gè)西班牙殖民地古巴，波多黎各，關(guān)島和菲律賓。據(jù)官方統(tǒng)計(jì)，美國鼓勵他們自我管理。實(shí)際上，美國保持控制。外國政策里的理想主義與防止可能會導(dǎo)致歐洲力量得到領(lǐng)土而向美國動用武裝力量的意愿共存。美國人也尋求新的市場，他們可以出售自己的商品。到19世紀(jì)末，美國開始出現(xiàn)越來越多的世界強(qiáng)國。
