A new article by Michael Stevenson appears in the latest issue of the the journal Diplomacy and Statecraft. “A Very Careful Balance:” The 1961 Triangular Agreement and the Conduct of Canadian–American Relations" examines the negotiation of a critical 1961 defence production agreement between Canada and the United States. Through this triangular transaction, the United States transferred American F-101 interceptors to Canadian ownership and paid $150 million to procure F-104 fighters in Canada. In return, Canada contributed $50 million to the F-104 project and assumed the significant costs of operating stations in the Pinetree radar line.
