Who Killed the Canadian Military? is a 2004 non-fiction book by J. L. Granatstein, a Canadian historian and military veteran. It examines and critiques the dilapidated state of the Canadian military. It also argues that a well-funded and well-trained military is necessary, given the then current international climate, and that increased military spending is necessary for Canada to survive as a nation. The book received mainly positive reviews from both the Canadian Military Journal and H-Net.
