Traces the competing strategies and goals, and struggles for manpower and material that have shaped American military institutions.

    In this important book, Hal Brands explains why grand strategy is a concept that is so alluring--and so elusive--to those who make American statecraft. He explores what grand strategy is, why it is so essential, and why it is so hard to get right amid the turbulence of global affairs and the chaos of domestic politics. At a time when grand strategy is very much in vogue, Brands critically appraises just how feasible that endeavor really is.Brands takes a historical approach to this subject, examining how four presidential administrations, from that of Harry S. Truman to that of George W. Bush, sought to do grand strategy at key inflection points in the history of modern U.S. foreign policy. As examples ranging from the early Cold War to the Reagan years to the War on Terror demonstrate, grand strategy can be an immensely rewarding undertaking--but also one that is full of potential pitfalls on the long road between conception and implementation. Brands concludes by offering valuable suggestions for how American leaders might approach the challenges of grand strategy in the years to come.

    Polk was elected president in 1844, the United States was locked in a bitter diplomatic struggle with Britain over the rich lands of the Oregon Territory, which included what is now Washington, Oregon, and Idaho. Texas, not yet part of the Union, was threatened by a more powerful Mexico. And the territories north and west of Texas -- what would become California, Nevada, Utah, Arizona, New Mexico, and part of Colorado -- belonged to Mexico. When Polk relinquished office four years later, the country had grown by more than a third as all these lands were added. The continental United States, as we know it today, was established -- facing two oceans and positioned to dominate both. In a one-term presidency, Polk completed the story of America's Manifest Destiny -- extending its territory across the continent, from sea to sea, by threatening England and manufacturing a controversial and unpopular two-year war with Mexico that Abraham Lincoln, in Congress at the time, opposed as preemptive. Robert Merry tells this story through powerful debates and towering figures -- the outgoing President John Tyler and Polk's great mentor, Andrew Jackson; his defeated Whig opponent, Henry Clay; two famous generals, Zachary Taylor and Winfield Scott; Secretary of State James Buchanan (who would precede Lincoln as president); Senate giants Thomas Hart Benton and Lewis Cass; Daniel Webster and John C. Calhoun; and ex-president Martin Van Buren, like Polk a Jackson protégé but now a Polk rival. This was a time of tremendous clashing forces. A surging antislavery sentiment was at the center of the territorial fight. The struggle between a slave-owning South and an opposing North was leading inexorably to Civil War. In a gripping narrative, Robert Merry illuminates a crucial epoch in U.S. history.
