As Chair of the Commons Defence Committee, he was a strong advocate for increased military spending both before and after the September 11 attacks in the United States in 2001. Under his leadership, the defence committee released a report entitled: "Facing Our Responsibilities: The state of readiness of the Canadian Forces" which called for substantial new investments in Canada’s military capabilities. As committee chair, Pratt also argued strongly for a more bi-partisan approach to defence issues and for regular reviews of Canadian foreign and defence policy. He successfully sponsored a resolution in Parliament to declare the first Sunday in June "Canadian Forces Day" and contributed to policy debates on defence and security matters with two papers: "Fostering Human Security: A Joint Canada-US Brigade," (October 2000) and "Does Canada Need A Foreign Intelligence Agency?" (March 2003).
