Like I said, Canada, though being a G8 nation, doesn't have to deal with the rest of the world even half as much as the U.S. does. More Americans who do pay attention to the rest of the world are more likely to pay attention to countries in Europe, Middle East, Africa, and Asia.
But MOST OF ALL..... the U.S. has another neighbour.....MEXICO!!!! Have you heard that the U.S.-Mexico border is the most crossed border in the world, with over 30 million crossings per year? That's similar to Canada's total population! I work in the public schools, where I often deal with classrooms that are predominantly Mexican/Hispanic - sometimes entire classrooms are 100% Hispanic. Letters home get translated in Spanish, bilingual education classrooms are left and right, heck California is now 40% Hispanic!
Sure, I've also met Canadians in the public schools here. They blend in better than not only immigrants from all the other countries, but even better than AMERICANS from southern and midwestern states!!! For one thing, they don't have accents that people from Arkansas do. How can we notice them if they don't stick out that much? At least we're not making their homework bilingual or serving poutine and maple syrup as part of their lunches!
Oh yeah, between Canada and the U.S., 1,000 officers patrol that border. 10 times as many people on the U.S. SIDE ALONE patrol the Mexican border. 500,000 people cross that border illegally every year! Can the Canadian border compare in how many cross that border?
Some estimates say that there are 8-12 million illegal immigrants in the U.S. One estimate says 20-38 million. The vast majority are Mexicans, many others are non-Mexicans who have used the Mexican border. Numbers that come from Canada are likely puny in comparison!!!
In fact, Canada should be concerned about Mexico too. I have read news stories about Mexicans who come illegally to the U.S. and live here for a while until fears of an illegal immigration crackdown come into play. Then they flee to Canada and seek asylum. And in fact, more and more Mexicans are doing that then ever.
Again, I agree that Americans should pay attention to the rest of the world. But should that time come, don't expect Canada to get much of it, unless Canadians start coming to the U.S. legally and illegally by the millions every year (which I don't see happening as long as Canada remains even more stable than the U.S. is, as it stands right now).
