“America goes not abroad, in search of monsters to destroy”—John Quincy Adams’s famous words are often quoted to justify noninterference in other nations’ affairs. Yet when he spoke them, Adams was not advocating neutrality or passivity but rather outlining a national policy that balanced democratic idealism with a pragmatic understanding of the young republic’s capabilities and limitations. America’s rise from a confederation of revolutionary colonies to a world power is often treated as inevitable, but Charles N. Edel’s provocative biography of Adams argues that he served as the central architect of a grand strategy that shaped America’s rise. Adams’s particular combination of ideas and policies made him a critical link between the founding generation and the Civil War–era nation of Lincoln.

Examining Adams’s service as senator, diplomat, secretary of state, president, and congressman, Edel’s study of this extraordinary figure reveals a brilliant but stubborn man who was both visionary prophet and hard-nosed politician. Adams’s ambitions on behalf of America’s interests, combined with a shrewd understanding of how to counter the threats arrayed against them, allowed him to craft a multitiered policy to insulate the nation from European quarrels, expand U.S. territory, harness natural resources, develop domestic infrastructure, education, and commerce, and transform the United States into a model of progress and liberty respected throughout the world.

While Adams did not live to see all of his strategy fulfilled, his vision shaped the nation’s agenda for decades afterward and continues to resonate as America pursues its place in the twenty-first-century world.

On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by Nuclear Forces, a riveting biography of Bethe’s early life and development as both a scientist and a man of principle.

As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems he knew he could solve.

Bethe’s emotional maturation was shaped by his father and by two women of Jewish background: his overly possessive mother and his wife, who would later serve as an ethical touchstone during the turbulent years he spent designing nuclear bombs. Situating Bethe in the context of the various communities where he worked, Schweber provides a full picture of prewar developments in physics that changed the modern world, and of a scientist shaped by the unprecedented moral dilemmas those developments in turn created.
