During the Cold War, defense planners continuously assumed the need to prepare for a possible major war against the Warsaw Pact plus at least one other conflict. After the Cold War, the big scenario went away, and U.S. ground forces were sized and shaped primarily to maintain what was called a two-regional-war capability. The wars were assumed to begin in fairly rapid succession (though not exactly simultaneously), and then overlap, lasting several months to perhaps a year or two. Three administrations and five defense secretaries, starting with President George H.W. Bush and defense chief Dick Cheney, endorsed some variant of it. And to some extent, they were all vindicated in recent years as the nation fought two overlapping regional conflicts, even if one of them was in Richard Haass's memorable phrase a "war of choice," and even if the wars went on far longer than standard planning scenarios assumed.
