One was While Canada Slept: How Canada lost its place in the World by Aandrew Cohen. I believe he is a writer for the Toronto Globe & Mail. It is a good book. Apprently even through the 1980's under Mulroney the budget was slashed for defence. It was accelerated when Chretien took office and completely gutted the military. The book doe snot only focus on defence it also focuses of Canadian foreign policy and trade.
