Making use of newly-researched archival materials, this collection of original essays on wartime and post-war US foreign policy re-evaluates well-known crises and documents many less familiar aspects of the nation's mid-twentieth century conflicts. Leading diplomatic historians address familiar subjects from new angles. They offer new evidence about the risks run and the costs incurred in the prosecution of the Cold War, from Korea to the Caribbean. And they provide an up-to-date accounting of mid-twentieth century American diplomacy's global purposes and consequences.
