It's less naïveté than the incentives of democratic politics, which drive the government to find quick wins—for example, to achieve relief for particular sectors such as canola—and ultimately to deliver quick economic benefits and let someone else in the future worry about the long-term strategic implications.
It requires changing incentives. I don't think it's a lack of understanding but rather the pressure to focus on short-term objectives and not worry about long-term outcomes. That is a great risk for Canada.
