It has been suggested that "The Defence strategic priorities for several decades have been Canada, North America and then either NATO or the UN depending on the flavor of the government, or both".
These are priorities but they do not constitute strategy. They are merely a set of "spending" priorities.
Rethinking Canadian Defence Strategy is inordinately complicated by the fact that US Defense Strategy is in disarray and its doctrine in serious need of a top to bottom rethink. To this we have had repeated suggestions from the US President that he wants Canada to be the 51st state, to take over Greenland and the Panama Canal and has begun to act in ways not dissimilar to Russia's incremental occupation of Belarus.
Canada like the U.S. is having a very difficult time in reorienting its thinking to include rapid change in drone technology, the cybersphere and AI. All aspects of military strategy and operations are in flex.
Defence doctrine is re-written everywhere. Organization needs to be rethought. The world has changed.
