This essay is a brief history of the U.S. army during the years immediately following the Korean War. For many in our own time that period—corresponding to the two terms of the Eisenhower presidency—has acquired an aura of congenial simplicity. Americans who survived Vietnam, Watergate, and painful economical difficulties wistfully recall the 1950s as a time when the nation possessed a clearly-charted course and had the will and the power to follow it.
