Foreign policy is a tricky business. Typically, challenges and proposed solutions are perceived as disparate unless a leader can amass enough support for an idea that creates alignment. And because the prime minister is typically the one proposing that idea - deciding what will be on the agenda and whether timing permits a workable, winnable solution - Canadian foreign policy can be summarized through the actions of these leaders. Statesmen, Strategists, and Diplomats explores how prime ministers from Sir John A. Macdonald to Justin Trudeau have shaped foreign policy by manipulating government structures, adopting and rejecting options, and imprinting their personalities on the process. Contributors provide fresh, sometimes surprising perspectives on a wide range of policy decisions - increasing or decreasing department budgets, forming or ending alliances, pursuing trade relationships, and the management of the prime minister's personal diplomacy - particularly as these choices affected the bureaucracies that deliver foreign policy diplomatically and militarily. No other book has been devoted to a systematic analysis of the central role of Canadian prime ministers in fashioning foreign policy. This innovative focus is destined to trigger a new appreciation for the formidable personal attention and acuity involved in a successful approach to external affairs.
