In , editors Andrew L. Johns and Mitchell B. Lerner bring together eleven essays that reflect the growing methodological diversity that has transformed the field of diplomatic history over the past twenty years. The contributors examine a spectrum of diverse domestic factors ranging from traditional issues like elections and Congressional influence to less frequently studied factors like the role of religion and regionalism, and trace their influence on the history of US foreign relations since 1945. In doing so, they highlight influences and ideas that expand our understanding of the history of American foreign relations, and provide guidance and direction for both contemporary observers and those who shape the United States' role in the world. This expansive volume contains many lessons for politicians, policy makers, and engaged citizens as they struggle to implement a cohesive international strategy in the face of hyper-partisanship at home and uncertainty abroad.
