Building a Special Relationship examines an under-appreciated time in foreign relations between the United States and Canada during the 1950s, when North American officials formed a culture of bilateral cooperation under the shadow of a growing Cold War. This work asserts that the Eisenhower era was critical to the evolution of diplomatic dealings between Canada and America. Under President Eisenhower and Prime Ministers St. Laurent and Diefenbaker, policy makers collaborating in Ottawa and Washington achieved what authors Asa McKercher and Michael D. Stevenson deem to be "tolerant accommodation" on significant issues of the day. Despite often disagreeing on their path forward but by embracing shared political ideologies and goals, both nations found common ground on matters such as defence, foreign policy, economic growth, and natural resource management. Building a Special Relationship is a significant contribution to the scholarly understanding of Canadian diplomacy during a formative era for Ottawa. Drawing on a wide array of archival sources, this book presents a vital new interpretation of how North American diplomacy in the Eisenhower years continues to influence what is often characterized as the "special relationship" between Canada and the United States.
