In 1999, Canada participated in NATO’s Operation Allied Force, a seventy- eight-day bombing campaign against Yugoslavia meant to end the ethnic cleansing of Kosovar Albanians. Officially, Canada’s interests in developing its foreign policy toward Kosovo were humanitarian and regional stability considerations. These were shared with the rest of its NATO allies. Thus, on the surface, it would seem that Canada and its NATO allies had similar concerns during the decision-making process around Kosovo. Digging deeper, an analysis of the primary sources available suggests that Canada did, in fact, have additional and unique considerations during the Kosovo crisis, namely national unity. This analysis amply illustrates the close interconnection between domestic issues and Canadian foreign policy. During the Kosovo War, Canada had to balance sovereignty sensitivities with humanitarian concerns. From the first time Kosovo was mentioned in Parliament on 18 November 1991 to the end of the Kosovo War on 11 June 1999, Canadian parliamentarians attempted to distinguish what Canada’s views on Kosovo were. Historians have likewise been occupied with the same task: distinguishing the Canadian contribution and position. Like the parliamentarians, not one of the Canadian historians who has written on the topic has questioned the official government version of what motivated Canada’s policy in Kosovo. They all credit a combination of humanitarian and regional concerns. Therefore, there was consensus at the time, and has been since, about what motivated Canada’s policy toward Kosovo. However, an analysis of the primary sources reveals that Canada did in fact have an additional and unique consideration during the Kosovo crisis: national unity. Canada’s domestic national unity issue influenced Canadian foreign policy toward Kosovo at every stage.
