"You don't even seem to really disagree that it wasn't a sensible purchase for canada, if only because you don't seem to believe that Canada has a plan for its military that is sufficiently fleshed out to justify it."

That is a pretty fair assessment of my position, though I do think there are reasons why the F-35 makes sense, depending on what the Canadian air forces are supposed to do. The F-35 is a very capable aircraft, it's just not clear if the capabilities are suited to Canada's missions.
