Reаd the pаssаge and chооse the main pattern оf organization. History never repeats itself exactly, but there are close parallels, such as that between the American Revolution and the Vietnam War. In both cases, an extremely powerful country was fighting thousands of miles from home against a relatively small native army, which was supported and supplied by a third country. In the case of the Revolution, France was the third country; in the case of Vietnam, it was the Soviet Union. Just as the British, with their command of the sea, could land troops wherever they wished on the Atlantic coast, so could the United States, with its air superiority, airlift troops wherever it wished in Vietnam. Both wars were extremely unpopular at home. But the most striking of the resemblances between the two is that while both great powers often defeated their enemies in large battles, neither was eventually able to win the war.
