Quick Geography lesson, we are in North America, our transportation network, road, rail, and river links us to just one other country, our largest trading parner, the largest economy in all of the Americas (North, Central and South). Europe has united into the EU to recognize and exploit the high level of their own economic integration, to allow them to out compete us. We formed NAFTA because it was the best way to make North America competative against the EU, and the rise of the Asia. Our choices are roughly these; recognize that Canada, the US and Mexico form a single economic entity that will succeed or fail together, or, pretend that our economies have nothing to do with each other, and just wonder why ours sneezes everytime theirs (US) gets a cold. In the first option, we are helping to direct and enhance our joint economic growth, in the other we are simply silent (and less effective) partners in the same struggle, with no knowledge or control over our economic destiny.
Canada and the US jointly defend our shores, our economies jointly exploit our resources and skills, we are two seperate nations, but we have grown so interconnected for so long, that for either of us to pretend otherwise impossible. Free Trade makes North America more competative in the world. Protectionism allows Canadian and US special interest groups to score points off each other, while losing to the rest of the world. We will succeed or fail together, and our leaders have to recognize this. If our leaders would recgonize the corallary to this, and rebuild Canada's defence and foreign service to the point where we were internationally relavent again, we would resume our place as a partner, rather than de facto protecterate of the US.
