In 1957, Lester Pearson won the Nobel Peace Prize for creating the United Nations Emergency Force during the Suez crisis. The award launched Canada's enthusiasm and reputation for peacekeeping. Pearson's Peacekeepers explores the reality behind the rhetoric by offering a detailed account of the UNEF's decade-long effort to keep peace along the Egyptian-Israeli border. While the operation was a tremendous achievement, the UNEF also encountered formidable challenges and problems. This nuanced account of Canada's participation in the UNEF challenges perceived notions of Canadian identity and history and will help Canadians to accurately evaluate international peacekeeping efforts today.
