I have an op-ed this week at Embassy magazine, written for the Canadian foreign policy community. It may or may not be gated. The basic gist is that the military of any country, including Canada, may want particular capabilities now but that will not necessarily affect where and how the politicians deploy them. If the F-35 purchase, for instance, crowds out spending on the army, the politicians may still decide to participate in a multilateral effort involving infantry.
Anyhow, check it out if you can.
